By the end of the course, you can make robust, advanced, and beneficial programs and learn to apply Python in applications like Games, Artificial Intelligence, Machine Learning, Data Science, Administrative Management, and much more.

**b. ****Python for Everybody Specialization – Offered by the University of Michigan – [Coursera]**– It is another excellent pick to help you meet Andrew NG’s machine learning prerequisites. In this detailed specialization, there are five courses. The specialization takes approximately eight months, and you can complete it at a suggested pace of 3 hours per week.

**2. High-school level Mathematics** – Machine learning enthusiasts are often confused about the need and importance of mathematics in machine learning. Let us tell you that Mathematics knowledge is one of the prerequisites that you can’t ignore.

Computers can solve any mathematical calculation faster than humans. But, in machine learning course, knowledge of mathematics is not for solving math problems. Instead, this familiarity with help you understand the math application in the machine learning algorithms and their working.

In addition, fulfilling this prerequiste can equip you with the knowledge to pick the correct algorithm by accounting for its training time, accuracy, number of features, and complexity.

Moreover, both humans and computers perceive things differently. While we process an image in a two-dimensional or three-dimensional form, mathematics is needed for the computer to process images. Mathematics also aids in assessing the uncertainty and interval and choosing suitable validation methods and parameter values.

Lastly, another reason Mathematics is one of the top crucial machine learning Stanford Coursera prerequisites is that your math knowledge will bestow you with the bias-variance trade-off understanding. It helps you find the underfitting and overfitting issues, the primary concerns in any ML model.
