How this course will help you?

A Verifiable Certificate of Completion is presented to all students who undertake this Machine learning advanced course.

If you are a business manager or an executive, or a student who wants to learn and apply machine learning in Real world problems of business, this course will give you a solid base for that by teaching you some of the advanced technique of machine learning, which are Decision tree, Random Forest, Bagging, AdaBoost and XGBoost.

Why should you choose this course?

This course covers all the steps that one should take while solving a business problem through Decision tree.

Most courses only focus on teaching how to run the analysis but we believe that what happens before and after running analysis is even more important i.e. before running analysis it is very important that you have the right data and do some pre-processing on it. And after running analysis, you should be able to judge how good your model is and interpret the results to actually be able to help your business.

What makes us qualified to teach you?

The course is taught by Abhishek and Pukhraj. As managers in Global Analytics Consulting firm, we have helped businesses solve their business problem using machine learning techniques and we have used our experience to include the practical aspects of data analysis in this course

We are also the creators of some of the most popular online courses - with over 150,000 enrollments and thousands of 5-star reviews like these ones:

This is very good, i love the fact the all explanation given can be understood by a layman - Joshua

Thank you Author for this wonderful course. You are the best and this course is worth any price. - Daisy

What is covered in this course?

This course teaches you all the steps of creating a decision tree based model, which are some of the most popular Machine Learning model, to solve business problems.

Below are the course contents of this course :

  • Section 1 - Introduction to Machine Learning

    In this section we will learn - What does Machine Learning mean. What are the meanings or different terms associated with machine learning? You will see some examples so that you understand what machine learning actually is. It also contains steps involved in building a machine learning model, not just linear models, any machine learning model.

  • Section 2 - R basic

    This section will help you set up the R and R studio on your system and it'll teach you how to perform some basic operations in R.

  • Section 3 - Pre-processing and Simple Decision trees

    In this section you will learn what actions you need to take to prepare it for the analysis, these steps are very important for creating a meaningful.

    In this section, we will start with the basic theory of decision tree then we cover data pre-processing topics like  missing value imputation, variable transformation and Test-Train split. In the end we will create and plot a simple Regression decision tree.

  • Section 4 - Simple Classification Tree

    This section we will expand our knowledge of regression Decision tree to classification trees, we will also learn how to create a classification tree in Python

  • Section 5, 6 and 7 - Ensemble technique
    In this section we will start our discussion about advanced ensemble techniques for Decision trees. Ensembles techniques are used to improve the stability and accuracy of machine learning algorithms. In this course we will discuss Random Forest, Bagging, Gradient Boosting, AdaBoost and XGBoost.

By the end of this course, your confidence in creating a Decision tree model in R will soar. You'll have a thorough understanding of how to use Decision tree  modelling to create predictive models and solve business problems.

Below is a list of popular FAQs of students who want to start their Machine learning journey-

What is Machine Learning?

Machine Learning is a field of computer science which gives the computer the ability to learn without being explicitly programmed. It is a branch of artificial intelligence based on the idea that systems can learn from data, identify patterns and make decisions with minimal human intervention.

What are the steps I should follow to be able to build a Machine Learning model?

You can divide your learning process into 3 parts:

Statistics and Probability - Implementing Machine learning techniques require basic knowledge of Statistics and probability concepts. Second section of the course covers this part.

Understanding of Machine learning - Fourth section helps you understand the terms and concepts associated with Machine learning and gives you the steps to be followed to build a machine learning model

Great course for learning different different libraries in python good explanation

By Ann Britt Skjerve on 8/25/2024

A very insightful and well-structured course. The combination of theoretical examples and practical work in R makes the complex concepts it covers understandable. Thank you!

By Nwachukwu Ikenna Josiah on 3/4/2024

Yes, it was educative. Thanks.

By Colin Ryan on 10/3/2023

A little too much time on how to do basics of R, i.e. install packages, for my liking, but I completely understand why it's in there

By Ebojielu Samuel on 9/20/2022

This course have been amazing and very explanatory so far especially with the examples in the videos. It is one of the best online course I can never forget. Thank you so much for this.

By Alokkumar Mahato on 7/19/2021

Excellent Teaching. This Course is designed very beautifully and covers almost all concepts required for Machine Learning.

By Aditya Chandra on 2/3/2021

This course only provides R code without any concrete concepts. . The concepts are so shallow that hardly one can understand fundamentals about Decision Tree. U can learn the R Code from this course without the understanding of why u are applying them. The worst course i have come up in Udemy

By Sabrina Carlos on 8/31/2020

I have a background in computer science but not R. This was very helpful and easy to follow along.

By Nikhil Dethe on 7/30/2020

I understood all the concepts. Really satisfied with the course. Specially the instructor really stick to the point and covered all the need full things promised.

By Adrian Jiménez Chaves on 6/25/2020

The professor is amazing. He really does a good job explaining and has a nice and slow speech cadence.
