Join Free: Power Bi Report Development Crash Course

About this Guided Project

Hello,

In this project, we will see in detail the steps required to create a PowerBI report using PowerBI Desktop and also we will publish this report on PowerBI service in the respective workspace. 

This project is designed for beginners who have no idea about PowerBI so they can quickly get a glimpse of how to create a report in PowerBI.

Pre-requisites:
- PowerBI Account

Here is a brief description of the tasks we are going to perform in this project:

Task1: Get Data
In this task we will first see an overview of PowerBI Desktop and then using PowerBI Desktop we will connect to the source data using the Get Data option. At the end of this task we would have imported all the source data in PowerBI Desktop

Task2: Create Relationship & Calculated Columns
In this task, we will create relationships between different source tables imported in PowerBI. In this process of creating relationship, we will also see how to created a calculated column using DAX query language.

Task3: Customize field level properties
In this task, we will explore and customize different field level properties like datatype, summarization, hidden etc.

Task4: Create visualizations in report
In this task, we will see how to create different visualizations in the report. We will also see how to add filters or slicers. We will explore visualizations like line chart, pie chart, table etc.

Task5: Publish report to PowerBI service
In all previous tasks, we have developed the report in PowerBI Desktop which is the local application installed on our desktop. In this task, we will see how to publish the task in power bi service. 

All The Best !!

Python Coding challenge - Day 116 | What is the output of the following Python Code?

 


Code:

my_list = [1, 2]

new_list = my_list * 2

print(new_list)

Solution and Explanation: 

The above code creates a new list new_list by repeating the elements of my_list twice using the * operator. Here's the output of the code:

my_list = [1, 2]

new_list = my_list * 2

print(new_list)

Output:

[1, 2, 1, 2]

As you can see, the elements [1, 2] from my_list are repeated, resulting in a new list [1, 2, 1, 2]. The * operator in this context duplicates the elements of the list the specified number of times.

There are 6 modules in this course

In this first course of the AI Product Management Specialization offered by Duke University's Pratt School of Engineering, you will build a foundational understanding of what machine learning is, how it works and when and why it is applied.  To successfully manage an AI team or product and work collaboratively with data scientists, software engineers, and customers you need to understand the basics of machine learning technology.  This course provides a non-coding introduction to machine learning, with focus on the process of developing models, ML model evaluation and interpretation, and the intuition behind common ML and deep learning algorithms.  The course will conclude with a hands-on project in which you will have a chance to train and optimize a machine learning model on a simple real-world problem.

At the conclusion of this course, you should be able to:
1) Explain how machine learning works and the types of machine learning
2) Describe the challenges of modeling and strategies to overcome them
3) Identify the primary algorithms used for common ML tasks and their use cases
4) Explain deep learning and its strengths and challenges relative to other forms of machine learning
5) Implement best practices in evaluating and interpreting ML models

DevOps on AWS: Code, Build, and Test

 


What you'll learn

Understand the DevOps philosophies and its lifecycle

Implement and manage continuous delivery systems and methodologies on AWS

How to use the right tools to measure code quality by identifying workflow steps

DevOps is the combination of cultural philosophies, practices, and tools that increases an organization’s ability to deliver applications and services at high velocity: evolving and improving products at a faster pace than organizations using traditional software development and infrastructure management processes. This speed enables organizations to better serve their customers and compete more effectively in the market.

DevOps process can be visualized as an infinite loop, comprising these steps: plan, code, build, test, release, deploy, operate, monitor. Throughout each phase, teams collaborate and communicate to maintain alignment, velocity, and quality. This course in the DevOps on AWS specialization focuses on code, build and test parts of the workflow. We will discuss topics such as source control, best practices for Continuous Integration, and how to use the right tools to measure code quality, by identifying workflow steps that could be automated.

Hands-on Machine Learning with AWS and NVIDIA

 


There are 4 modules in this course

Machine learning (ML) projects can be complex, tedious, and time consuming. AWS and NVIDIA solve this challenge with fast, effective, and easy-to-use capabilities for your ML project.

Join Free: Hands-on Machine Learning with AWS and NVIDIA

This course is designed for ML practitioners, including data scientists and developers, who have a working knowledge of machine learning workflows. In this course, you will gain hands-on experience on building, training, and deploying scalable machine learning models with Amazon SageMaker and Amazon EC2 instances powered by NVIDIA GPUs. Amazon SageMaker helps data scientists and developers prepare, build, train, and deploy high-quality ML models quickly by bringing together a broad set of capabilities purpose-built for ML. Amazon EC2 instances powered by NVIDIA GPUs along with NVIDIA software offer high performance GPU-optimized instances in the cloud for efficient model training and cost effective model inference hosting.

In this course, you will first get an overview of Amazon SageMaker and NVIDIA GPUs. Then, you will get hands-on, by running a GPU powered Amazon SageMaker notebook instance. You will then learn how to prepare a dataset for model training, build a model, execute model training, and deploy and optimize the ML model. You will also learn, hands-on, how to apply this workflow for computer vision (CV) and natural language processing (NLP) use cases. After completing this course, you will be able to build, train, deploy, and optimize ML workflows with GPU acceleration in Amazon SageMaker and understand the key Amazon SageMaker services applicable to computer vision and NLP ML tasks.

Introduction to Designing Data Lakes on AWS

In this class, Introduction to Designing Data Lakes on AWS, we will help you understand how to create and operate a data lake in a secure and scalable way, without previous knowledge of data science! Starting with the "WHY" you may want a data lake, we will look at the Data-Lake value proposition, characteristics and components.

Designing a data lake is challenging because of the scale and growth of data. Developers need to understand best practices to avoid common mistakes that could be hard to rectify. In this course we will cover the foundations of what a Data Lake is, how to ingest and organize data into the Data Lake, and dive into the data processing that can be done to optimize performance and costs when consuming the data at scale. This course is for professionals (Architects, System Administrators and DevOps) who need to design and build an architecture for secure and scalable Data Lake components. Students will learn about the use cases for a Data Lake and, contrast that with a traditional infrastructure of servers and storage.

Learn how to go from raw data to meaningful insights using AWS with this one-week course. Throughout the course, you’ll learn about the fundamentals of Data Analytics from AWS experts.

Start off with an overview of different types of data analytics techniques - descriptive, diagnostic, predictive, and prescriptive before diving deeper into the descriptive data analytics. Then, apply your knowledge with a guided project that makes use of a simple, but powerful dataset available by default in every AWS account: the logs from AWS CloudTrail. The CloudTrail service enables governance, compliance, operational auditing, and risk auditing of your AWS account. Through the project you’ll also get an introduction to Amazon Athena and Amazon QuickSight. And, you’ll learn how to build a basic security dashboard as a simple but practical method of applying your newfound data analytics knowledge.
