Python Coding challenge - Day 850| What is the output of the following Python Code?

 


Code Explanation:

1. Class Definition Begins
class Demo:

A new class named Demo is created.
This class will contain attributes and methods.

2. Class-Level Attribute
    nums = []

nums is a class variable (shared by all objects of the class).

It is an empty list [] initially.

Any object of Demo will use this same list unless overridden.

3. Method Definition
    def add(self, val):
        self.nums.append(val)

The method add() takes self (object) and a value val.

It appends val to self.nums.

Since nums is a class list, appending through any object affects the same list.

4. Creating First Object
d1 = Demo()

Creates object d1 of class Demo.

d1 does not have its own nums; it uses the shared class list.

5. Creating Second Object
d2 = Demo()

Creates another object d2.

d2 also uses the same class-level list nums as d1.

6. Adding a Number Using d1
d1.add(4)

Calls the add() method on d1.

This executes self.nums.append(4).

Since nums is shared, the list becomes:
[4]

7. Printing Length of nums from d2
print(len(d2.nums))

d2 looks at the same shared list.

That list contains one element: 4

So length is:

1

Final Output:
1

Python Coding challenge - Day 849| What is the output of the following Python Code?

 


Code Explanation:

1. Class Definition Begins
class A:

You define a class A.
This is a blueprint for creating objects.

2. Method Inside Class A
    def show(self):
        return "A"

A method named show() is created.

When this method is called, it returns the string "A".

3. Class B Inherits Class A
class B(A):

Class B is created.

It inherits from class A, meaning B gets all attributes/methods of A unless overridden.

4. Overriding the show() Method in Class B
    def show(self):
        return super().show() + "B"

Class B overrides the show() method of class A.

super().show() calls the show() method from the parent class A, which returns "A".

Then "B" is added.

So the full returned string becomes: "A" + "B" = "AB".

5. Creating an Object of Class B
obj = B()

An object named obj is created using class B.

This object can use all methods of B, and inherited methods from A.

6. Calling the show() Method
print(obj.show())

Calls B’s version of show().

That method calls super().show() → returns "A"

Adds "B" → becomes "AB"

Finally prints:

AB

Final Output: AB

Maximizing Business Potential With AI: Protection And Growth Strategies To Multiply Your Business Faster While Avoiding AI Pitfalls

 


Maximizing Business Potential With AI: A Strategic Guide to Growth and Protection

Artificial Intelligence (AI) isn’t just a futuristic concept reserved for tech giants — it is a practical, powerful tool that can propel businesses forward while simultaneously protecting them from emerging risks. When used intelligently, AI offers a dual promise: accelerating growth and strengthening defenses. But without properly designed strategies, it can backfire or become a liability.

1. The Growth Engine: How AI Multiplies Business Potential

AI’s ability to analyze massive volumes of data allows businesses to make smarter, faster, and more informed decisions. Predictive analytics enables firms to forecast trends, customer demand, and market shifts, letting them stay one step ahead. Companies can use generative AI to scale marketing, automatically creating personalized content, targeted campaigns, and even product ideas — freeing human teams to focus on higher-level strategy and innovation.

Moreover, AI streamlines operations. From automating routine tasks like customer support (via chatbots) to optimizing inventory and supply chain logistics, AI helps reduce costs and improve efficiency. In human resources, AI-powered tools can help in recruitment, talent matching, and even predicting employee attrition, thereby making workforce planning more strategic.

Finally, AI fosters innovation. Businesses can experiment with new business models — for example, “AI as a service” or usage-based models that dynamically adjust pricing based on behavior. AI-driven insights can reveal unmet customer needs, and companies can prototype products faster using simulation and data-driven feedback.

2. The Protective Shield: Guarding Your Business With AI

Growth is exciting, but unguarded AI adoption carries risks — and smart companies need safeguards. AI-powered security systems can monitor networks for anomalies, detect cyberthreats in real time, and initiate preventive actions. This proactive defense reduces vulnerability and ensures business continuity.

On the compliance and risk front, AI helps too. By scanning regulatory changes, modeling risk scenarios, and assessing credit or fraud risk, AI tools enable businesses to stay ahead of compliance challenges. This not only protects from financial loss but also strengthens trust among stakeholders.

Moreover, building a governance framework around AI is critical. This includes setting ethical guidelines, establishing accountability, and ensuring transparency in AI decision-making. Businesses should audit AI systems regularly for bias, correctness, and fairness. Human oversight remains essential to verify AI outputs before critical decisions are made.

3. Avoiding the Pitfalls: Common Risks and Mitigation

Many AI projects fail because they are misaligned with business goals. Without clearly defined objectives and KPIs, AI initiatives can become expensive experiments with little return. It’s crucial to align AI deployment with the core strategic priorities of the business — whether that’s reducing costs, increasing revenue, or improving customer experience.

Poor data quality is another major risk. AI models trained on biased, incomplete, or noisy data can lead to flawed decisions — which can damage customers’ trust or even lead to regulatory penalties. Businesses must invest in robust data infrastructure, data cleaning, and data governance.

There’s also the risk of over‑reliance on AI. Blindly trusting AI-generated recommendations without human checks can lead to serious mistakes. Therefore, AI systems should be used as decision-support tools, not as fully autonomous decision-makers — especially in high-stakes areas.

Lastly, “AI washing” or exaggerating the role of AI in your products or services can damage credibility. Transparent communication about what AI actually does in your business builds trust and sets more realistic expectations.

4. Building an AI-Driven Business Culture

Adopting AI isn’t just a technology shift — it's a cultural transformation. To maximize value, businesses must build AI literacy across teams. Training employees, not just in how to use AI tools but in understanding their limits, helps build a mindset of experimentation tempered with responsibility.

Start with pilot projects in low-risk areas. Use these as learning grounds, measure success rigorously, and scale what works. Creating cross-functional teams — combining business experts, data scientists, and domain specialists — ensures that AI initiatives are grounded in real business value.

Feedback loops are vital. Use customer feedback, data insights, and model performance metrics to iterate on your AI models. This iterative approach helps refine AI applications and ensures they remain aligned with evolving business needs.

5. Future-Proofing With Responsible AI Strategy

The AI landscape is changing fast. To stay ahead, businesses need not only a strategy for adoption but a framework for governance and continuous evaluation. That means:

  • Defining ethical principles for AI aligned with your company values.

  • Setting up monitoring and auditing processes to check for bias, fairness, and accuracy.

  • Ensuring transparency so that AI-driven decisions can be explained and justified.

  • Being ready to adapt as regulations, technology, and business contexts evolve.

By embedding these practices, companies can enjoy the full potential of AI — growth, innovation, efficiency — without falling prey to the risks.

Practical Deep Learning: Master PyTorch in 15 Days

 

Introduction

Deep learning is one of the most in-demand skills in tech right now — powering everything from image classification and natural language processing to recommendation systems and autonomous driving. The challenge for many learners is: how do you actually build, train and deploy deep learning models — especially if you're short on time or want a structured roadmap.

This course addresses that need by offering a 15-day roadmap to mastering PyTorch, one of the leading deep-learning frameworks. It targets learners who want a hands-on, project-based path rather than purely theoretical content.


Why This Course Matters

  • It gives you a clear timeline: 15 consecutive days of focused deep-learning work — which helps maintain momentum and avoids getting lost in sprawling content.

  • It emphasises practical, deployable projects: you don’t just learn what CNNs or transfer learning are — you use them to build real models (spam filter, image classifier, price predictor) that you can show.

  • It uses PyTorch — which is highly relevant, both in research and industry. Mastering PyTorch gives you a strong edge.

  • It includes not just model building, but also deployment (e.g., using Gradio for interactive applications). That means you move from prototype to something usable.

  • Because many deep-learning courses are either too theoretical (heavy maths) or too superficial (just “click and run”) this course strikes a balance: teaching you what you need, coding what you need, deploying what you need.


What You’ll Learn

Here’s a breakdown of how the 15-day path is typically structured (based on the syllabus) and what knowledge/skills you’ll acquire.

Days 1-2: Foundations of Neural Networks & PyTorch

  • Basics of tensors, neural network structure (neurons → layers → networks), forward propagation, loss functions.

  • Get familiar with PyTorch: tensors, autograd (automatic differentiation), building simple networks.

  • From those days, you’ll build the confidence to start modelling.

Days 3-6: Regression & Binary Classification Projects

  • Example projects: predicting used car prices (regression), spam detection in SMS (binary classification).

  • You’ll learn data preprocessing, train/test split, loss choice (MSE for regression, cross‐entropy for classification), basic network architecture design.

  • You’ll gain exposure to how to handle real data: preparation, feature handling, evaluation.

Days 7-10: Multi-Class Classification & Convolutional Neural Networks

  • Projects: classification of handwritten digits, fashion items (multi-class).

  • You’ll dive into convolutional neural networks (CNNs): understanding convolution, pooling, channels, image data pipelines.

  • Learn transfer learning: using pre-trained models (like ResNet) for new tasks to boost performance.

  • At this stage you’ll build more complex architectures and understand how deeper networks differ.

Days 11-14: Transfer Learning, Model Optimisation & Deployment

  • Deepen your knowledge of transfer learning: fine-tuning, freezing layers, data augmentation.

  • Model optimisation: choosing architectures, regularisation techniques, monitoring overfitting, evaluating performance.

  • Projects culminate in building a strong image classification model for a domain (e.g., a real-world dataset) using transfer learning.

Day 15: Deploying Your Model

  • Learn how to deploy models into an interactive application: e.g., using Gradio (or similar) for an end-user interface.

  • Packaging your model, creating web interface for predictions.

  • Final exam or project presentation to consolidate what you’ve built.


Who Should Take This Course?

This course is ideal for:

  • Learners with basic Python knowledge (loops, functions, lists/dictionaries) who want to move into deep learning.

  • Data analysts or developers who know some machine-learning fundamentals and now want to specialise in neural networks, image/text modelling and deployment.

  • Hobbyists or career-changers eager to build real projects in deep learning and add them to their portfolio.

  • If you are completely new to programming or highly inexperienced, you may need to spend extra time on Python basics—but the course starts from the ground up so it’s still accessible.


How to Get the Most Out of It

  • Code along every day: Because it’s a daily roadmap, try to follow the schedule strictly—complete each day’s content, build the project, run the code, tweak it.

  • Modify the projects: Don’t just run the example as is—change datasets, change architecture, add or remove layers, change hyperparameters. Experimenting helps you learn deeper.

  • Deploy early and often: Building a deployable model makes learning concrete. Even a simple interface is a strong addition to your portfolio.

  • Document your work: For each project, write what you did, what you changed, what results you got. This becomes your portfolio and helps you reflect.

  • Review difficult concepts: Some days might involve more complexity (CNNs, transfer learning). Pause if needed and review until you feel confident.

  • Use a decent hardware setup: While many tasks can be done on CPU, using GPU (local or cloud) will accelerate training and make experimentation more feasible.

  • Extend beyond the syllabus: After finishing the 15-day roadmap, pick one project of your own choosing (e.g., classify your own image dataset, predict stock prices with CNNs/RNNs) to reinforce and deepen learning.


What You’ll Walk Away With

By the end of the course you should be able to:

  • Build, train and evaluate neural networks in PyTorch—regression, binary classification, multi-class classification, image classification.

  • Understand and apply advanced techniques like CNNs, transfer learning, data augmentation, and deploy models for real-world usage.

  • Take the code you build, adapt it, build new projects and demonstrate competence in deep learning workflows.

  • Have at least several mini-projects in your portfolio (spam filter, image classifier, price predictor, deployed app) that you can show to employers or for personal use.

  • Be equipped to explore more advanced deep learning topics (e.g., sequence models, generative networks) with confidence.

  • Install and experiment early: Set up your PyTorch environment at the outset—use Jupyter or Colab, test simple tensor operations, and build familiarity with the API.

  • Code along and modify: As you progress through training loops and architectures, don’t just reproduce what the instructor does—change hyperparameters, modify architectures, play with different datasets.

  • Build mini‑projects continuously: After each major topic (CNNs, RNNs, transfer learning), pick a small project of your own to reinforce learning. This helps transition from guided learning to independent problem‑solving.

  • Document your work: Keep notebooks, clear comments, results and reflections. This builds your portfolio and shows employers you can explain your decisions.

  • Focus on system design and deployment: While network architecture is important, many deep‑learning roles require integration, tuning, deployment and maintenance. So pay attention to those parts of the curriculum.

  • Review and iterate: Some advanced topics (e.g., generative models, deployment at scale) can be challenging—return to them, experiment, and refine until you feel comfortable.

  • Leverage your certificate: Once completed, showcase your certificate on LinkedIn, in your resume, and reference your capstone project(s). Talk about what you built, what you learned, and how you solved obstacles.


What You’ll Gain

By completing this Professional Certificate, you will:

  • Master PyTorch constructs and be able to build, train and evaluate neural networks for a variety of tasks.

Getting started with TensorFlow 2

 


Introduction

Deep learning frameworks have become central tools in modern artificial intelligence. Among them, TensorFlow (especially version 2) is one of the most widely used. The course “Getting started with TensorFlow 2” helps you build a complete end‑to‑end workflow in TensorFlow: from building, training, evaluating and deploying deep‑learning models. It’s designed for people who have some ML knowledge but want to gain hands‑on competency in TensorFlow 2.


Why This Course Matters

  • TensorFlow 2 introduces many improvements (ease of use, Keras integration, clean API) over earlier versions — mastering it gives you a useful, modern skill.

  • The course isn’t just theoretical: it covers actual workflows and gives you programming assignments, so you move from code examples to real model building.

  • It aligns with roles such as Deep Learning Engineer or AI Practitioner: knowing how to build and deploy models in TensorFlow is a strong industry‑skill.

  • It’s part of a larger Specialization (“TensorFlow 2 for Deep Learning”), so it fits into a broader path and gives you credential‑value.


What You’ll Learn

Here’s a breakdown of the course content and how it builds your ability:

Module 1: Introduction to TensorFlow

You’ll begin with setup: installing TensorFlow, using Colab or local environments, understanding what’s new in TensorFlow 2, and familiarising yourself with the course and tooling.
This module gets you comfortable with the environment and prepares you for building models.

Module 2: The Sequential API

Here you’ll dive into model building using the Keras Sequential API (which is part of TensorFlow 2). Topics include: building feed‑forward networks, convolution + pooling layers (for image data), compiling models (choosing optimisers, losses), fitting/training, evaluating and predicting.
You’ll likely build a model (e.g., for the MNIST dataset) to see how the pieces fit together.

Module 3: Validation, Regularisation & Callbacks

Models often over‑fit or under‑perform if you don’t handle validation, regularisation or training control properly. This module covers using validation sets, regularisation techniques (dropout, batch normalisation), and callbacks (early stopping, checkpoints).
You’ll learn to monitor and improve model generalisation — a critical skill for real projects.

Module 4: Saving & Loading Models

Once you have a trained model, you’ll want to save it, reload it, reuse it, maybe fine‑tune it later. There’s a module on how to save model weights, save the full model architecture, load and use pre‑trained models, and leverage TensorFlow Hub modules.
This ensures your models aren’t just experiments — they become reusable assets.

Module 5: Capstone Project

Finally, you bring together all your skills in a Capstone Project: likely a classification model (for example on the Street View House Numbers dataset) where you build from data → model → evaluation → prediction.
This is where you apply what you’ve learned end‑to‑end and demonstrate readiness.


Who Should Take This Course?

  • Learners who know some machine‑learning basics (e.g., supervised learning, basic neural networks) and want to build deeper practical skills with TensorFlow.

  • Python programmers or data scientists who might have used other frameworks (or earlier TensorFlow versions) and want to upgrade to TensorFlow 2.

  • Early‑career AI/deep‑learning engineers who want to build portfolio models and deployable workflows.

  • If you're completely new to programming, or to ML, you might find some modules challenging—especially if you haven’t done neural networks yet—but the course still provides a structured path.


How to Get the Most Out of It

  • Set up your environment: Use Google Colab or install TensorFlow locally with GPU support (if possible) so you can run experiments.

  • Code along every module: When the videos demonstrate building a model, train it yourself, modify parameters, change the dataset or architecture and see what happens.

  • Build your own mini‑projects: After you finish module 2, pick a simple image dataset (maybe CIFAR‑10) and try to build a model. After module 3, experiment with over‑fitting/under‑fitting by adjusting regularisation.

  • Save, load and reuse models: Practise the workflow of saving a model, reloading it, fine‑tuning it or using it for prediction. This makes you production‑aware.

  • Document your work: Keep Jupyter notebooks or scripts for each exercise, record what you changed, what result you got, what you learned. This becomes your portfolio.

  • Reflect on trade‑offs: For example, when you change dropout rate or add batch normalisation, ask: what changed? How did validation accuracy move? Why might that happen in terms of theory?

  • Connect to real use‑cases: Think “How would I use this model in my domain?” or “How would I deploy it?” or “What data would I need?” This helps make the learning concrete.


What You’ll Walk Away With

By the end of the course you will:

  • Understand how to use TensorFlow 2 (Keras API) to build neural network models from scratch: feed‑forward, CNNs for image data.

  • Know how to train, evaluate and predict with models: using fit, evaluate, predict methods; understanding loss functions, optimisers, metrics.

  • Be familiar with regularisation techniques and callbacks so your models generalise better and training is controllable.

  • Be able to save and load models, reuse pre‑trained modules, and build reproducible model workflows.

  • Have one or more mini‑projects or a capstone model you can demonstrate (for example for your portfolio or job interviews).

SQL for Data Science with R

 


Introduction

In the world of data science, a significant portion of the work involves querying and manipulating data stored in relational databases. The course “SQL for Data Science with R” bridges two essential skills for modern data practitioners: SQL, the language of relational databases, and R, a powerful language for statistical analysis and data science workflows.

By combining these, you will be able to work from raw data stored in databases, extract the relevant information, and then further analyse it using R — giving you a strong foundation for data‑driven projects.


Why This Course Matters

  • Much data in enterprises and research remains stored in relational databases. Knowing how to extract and manipulate that data using SQL is foundational.

  • R is a widely used language for data science, statistics and analytics. By learning how SQL and R work together, you gain a practical workflow that spans from data retrieval to analysis.

  • The course addresses hands‑on skills rather than just theory: you’ll practice with real databases, real datasets, and combine database queries with R code.

  • The course is beginner‑friendly: no prior knowledge of SQL, R or databases is required — making it accessible yet highly applicable.


What You’ll Learn

Here’s a breakdown of the key modules and learning outcomes in the course:

Module 1 – Getting Started with SQL

You’ll begin with the basics of SQL: how to connect to a database, use SELECT statements, simple filters, COUNT, DISTINCT, LIMIT, and basic data retrieval operations.
Outcome: You’ll be able to run simple queries and understand the syntax of SQL in a data science context.

Module 2 – Introduction to Relational Databases and Tables

Here you’ll learn about how databases work: tables, columns, relationships, data definition (DDL) vs data manipulation (DML). You’ll create tables, use CREATE, ALTER, DROP, TRUNCATE, and understand how databases are structured.
Outcome: You gain ability to structure databases and understand how to store and adjust datasets within them.

Module 3 – Intermediate SQL

This module covers more sophisticated SQL features: string patterns and ranges, sorting results, grouping, built‐in functions, date/time functions, sub‑queries, nested selects, working with multiple tables (joins).
Outcome: You’ll be able to write SQL queries that pull and combine data across tables, filter and group intelligently, and handle intermediate‑level database operations.

Module 4 – Getting Started with Databases Using R

Now you shift into R: you’ll learn how R and databases interact. You’ll connect to a database from R (via ODBC or RJDBC), explore R data frames vs relational tables, persist R data, and work with metadata.
Outcome: You’ll understand how to integrate SQL queries within your R code and treat relational data as part of a data‑science workflow.

Module 5 – Working with Database Objects Using R

In this module you will build database objects via R, load data, construct logical and physical models, query data from R, and then analyse the retrieved data.
Outcome: You’ll be able to extract data using SQL within R, then perform analysis (statistical, visual) on that data using R’s capabilities.

Course Project

A hands‑on project where you apply what you’ve learned: you’ll work with real datasets (for example, crop data, exchange rates), design queries, extract and analyse data, interpret results and present findings.
Outcome: You will have completed an end‑to‑end workflow: database → query → R analysis → insight.


Who Should Take This Course?

  • Anyone wanting to become a data scientist, data analyst or data engineer and looking to build foundational skills in how data is stored and retrieved.

  • R programmers who have done data manipulation or visualisation but haven’t yet worked with SQL or databases.

  • Professionals from other domains (business, research, analytics) who want to expand their toolkit with database querying + R analysis.

  • If you have no programming or database background, you can still take the course — it’s designed for beginners — but you’ll benefit from working steadily through early modules.


How to Get the Most Out of It

  • Install and experiment: Use RStudio (or Jupyter with R kernel) and connect to a live or local database (e.g., SQLite or a cloud instance). Run queries, change filters, experiment.

  • Code along: Whenever examples show SQL statements or R code, type them out, run them, alter tables or queries, see how results change.

  • Integrate SQL + R: Do not treat SQL and R as separate—they work together. For example, write a SQL query to retrieve data, then use R to visualise or model the data.

  • Build your own project: After the modules, pick a dataset you care about. Load it into a database, write a set of queries to extract insights, then analyse it in R.

  • Keep a portfolio: Document your queries, your R code, data visualisations and insights. Save the notebook or document so you can show someone else what you did.

  • Reflect on best practices: Ask yourself: How efficient is my SQL query? How clean is my data before I analyse it? Are my tables structured well? Could I join or normalise differently?

  • Connect to next steps: After finishing, you'll be ready to handle data pipelines, larger analytics workflows, advanced R models, or move into machine learning—but this course gives you the database and query foundation.


What You’ll Walk Away With

  • A working knowledge of relational databases, how to design tables, how to manipulate them via SQL.

  • Skills to write SQL statements from simple to intermediate level: selecting, inserting, updating, deleting, filtering, grouping, joining.

  • Ability to connect R to a database, extract data and perform analysis and visualisation in R.

  • Practical experience working with real databases and datasets, designing queries and extracting meaningful insights.

  • A stronger readiness for data‑science roles where working with data in databases is integral, and a better understanding of how data flows into your analysis.

Conclusion

“SQL for Data Science with R” offers an excellent foundational course for anyone looking to combine database querying skills with data‑science workflows in R. By mastering SQL and R together, you step into a serious data‑science mindset—able not just to analyse data, but to retrieve and prepare it from databases.

Machine Learning for Data Analysis


Introduction

In many projects, data analysis ends with exploring and summarising data. But real value comes when you start predicting, classifying or segmenting — in other words, when you apply machine learning (ML) to your analytical workflows. The course Machine Learning for Data Analysis focuses on this bridge: taking analysis into predictive modelling using ML algorithms. It shows how you can move beyond descriptive statistics and exploratory work, and start using algorithms like decision trees, clustering and more to draw deeper insights from your data.


Why This Course Matters

  • Brings machine learning to analysis workflows: If you already do data analysis (summarising, plotting, exploring), this course helps you add the ML layer — allowing you to build predictive models rather than simply analyse past data.

  • Covers a variety of algorithms: The course goes beyond the simplest models to cover decision trees, clustering, random forests and more — giving you multiple tools to apply depending on your data and problem. 

  • Hands‑on orientation: It includes modules that involve using real datasets, working with Python or SAS (depending on your background) — which helps you gain applied experience.

  • Part of a broader specialization: It sits within a larger “Data Analysis and Interpretation” specialization, so it fits into a workflow of moving from data understanding → analysis → predictive modelling. 

  • Improves decision‑making ability: With ML models, you can go from “What has happened” to “What might happen” — which is a valuable shift in analytical thinking and business context.


What You’ll Learn

Here’s a breakdown of the course content and how it builds your capability:

Module 1: Decision Trees

The first module introduces decision trees — an intuitive and powerful algorithm for classification and regression. You’ll look at how trees segment data via rules, how to grow a tree, and understand the bias‑variance trade‑off in that context. 
You’ll work with tools (Python or SAS) to build trees and interpret results.

Module 2: Random Forests

Next, you’ll build on decision trees towards ensemble methods — specifically random forests. These combine many trees to improve generalisation and reduce overfitting, giving you stronger predictive performance. According to the syllabus, this module takes around 2 hours.

Additional Modules: Clustering & Unsupervised Techniques

Beyond supervised methods, the course introduces unsupervised learning methods such as clustering (grouping similar items) and how these can support data analysis workflows by discovering hidden structure in your data.

Application & Interpretation

Importantly, you’ll not just train models — you’ll also interpret them: understand variable importance, error rates, validation metrics, how to choose features, handle overfitting/underfitting, and how to translate model output into actionable insights. This ties machine learning back into the data‑analysis context.


Who Should Take This Course?

This course is ideal for:

  • Data analysts, business analysts or researchers who already do data exploration and want to add predictive modelling to their toolkit.

  • Professionals comfortable with data, some coding (Python or SAS) and basic statistics, and who now want to apply machine learning algorithms.

  • Students or early‑career data scientists who have done basic analytics and want to move into ML models rather than staying purely descriptive.

If you are totally new to programming, statistics or machine learning, you may find parts of the course challenging, but it still provides a structured path with approachable modules.


How to Get the Most Out of It

  • Follow and replicate the examples: When you see a decision‑tree or clustering example, type it out yourself, run it, change parameters or datasets to see the effect.

  • Use your own data: After each module, pick a small dataset (maybe from your work or public data) and apply the algorithm: build a tree, build a forest, cluster the data—see what you discover.

  • Understand the metrics: Don’t just train and accept accuracy — dig into what the numbers mean: error rate, generalisation vs over‑fitting, variable importance, interpretability.

  • Connect analysis → prediction: After exploring data, ask: “If I had to predict this target variable, which algorithm would I pick? How would I prepare features? What would I do differently after seeing model output?”

  • Document your learning: Keep notebooks of your experiments, the parameters you changed, the results you got—this becomes both a learning aid and a portfolio item.

  • Consider the business/research context: Think about how you would explain the model’s output to non‑technical stakeholders: what does the model predict? What actions would you take? What are the limitations?


What You’ll Walk Away With

By the end of this course you will:

  • Be able to build decision trees and random‑forest models for classification and regression tasks.

  • Understand unsupervised techniques like clustering and how they support data‑analysis by discovering structure.

  • Gain hands‑on experience applying ML algorithms to real data, interpreting results, and drawing insights.

  • Bridge the gap between exploratory data analysis and predictive modelling; you will be better equipped to move from “what happened” to “what might happen.”

  • Be positioned to either continue deeper into machine learning (more algorithms, deep learning, pipelines) or apply these new skills in your current data‑analysis role.
