## Is Andrew Ng’s Machine Learning Course Worth Your Time And Money?

If you are a beginner in machine learning, and you are interested in starting a career in this exciting field, you definitely want to sign up for Machine Learning course by Andrew Ng on Coursera. This Stanford University sponsored online ML course has been created with easy to understand videos and tutorials. However, if you already know the basics of ML algorithms like SVM, logistic regression, and basic neural network, you may skip this course and move on to the deep learning specialization. Also, learners who are conversant with the basics of neural networks can skip the first three courses and move on to the 4^{th} and 5^{th} courses where they will learn about CNN and RNN.

## Who is Andrew Ng?

Andrew Ng is the co-founder of Coursera and a former chief scientist at Baidu where he was responsible for driving the search engine’s global AI infrastructure and strategy. He is also a professor of computer science at Stanford University. Andrew was also the founding lead of the Google Brain deep learning project. He has authored hundreds of papers in ML, robotics, and related fields.

## Is Andrew Ng’s machine learning course right for you?

If you are keen to learn about Machine Learning and are looking to gain a deeper understanding of the inner working of the algorithms, then this ML course by Andrew Ng is a great fit for you. While this is one of the oldest online ML courses, it does an excellent job explaining the basic concepts in order to help you better understand the Machine Learning algorithms that are currently in use.

If you are hoping to gain a general overview of how Machine Learning works and learn some tool or library to perform basic ML tasks then you are better off signing up for other online courses like Udacity Machine Learning Nanodegree.

This course is prepared with technically-focused learners in mind. It heavily applies Mathematics to explain algorithms. As such, it is important that you have a basic understanding of Linear Algebra and Calculus in order to have a grasp of how the algorithms work. And unlike most ML courses that use Python, all the assignments in this course are in MATLAB.
