Course 1: Machine Learning by Stanford University (Coursera)
- Instructor: Andrew Ng
- Level: Beginner to Intermediate
- Platform: Coursera
This course is one of the most well-known and widely recommended introductions to machine learning. Andrew Ng, a co-founder of Google Brain and former head of Baidu AI Group, walks you through the core concepts of machine learning, data mining, and statistical pattern recognition.
The course is structured to gradually introduce you to machine learning techniques like linear regression, logistic regression, neural networks, and more. What sets this course apart is its hands-on approach, with real-world applications such as speech recognition, web search, and self-driving cars. You’ll also gain experience with the Octave programming environment, which allows for easy implementation of algorithms.
This course provides a holistic view of machine learning, making it a perfect starting point for anyone serious about diving deep into algorithms. You can access it for free, although there’s an option to pay for a certificate.
Course 2: Introduction to Machine Learning for Coders (fast.ai)
- Instructors: Jeremy Howard, Sylvain Gugger
- Level: Intermediate
- Platform: fast.ai
This course is designed for people who already have some coding experience, particularly in Python. If you’re a programmer looking to transition into machine learning, this is an ideal starting point.
Created by fast.ai, this course focuses on practical coding experience and rapidly moves into implementing machine learning algorithms without getting bogged down by unnecessary theory.
What’s great about fast.ai’s approach is its emphasis on building models from day one. The course begins by showing you how to construct a state-of-the-art image classifier using deep learning and then goes on to explain the algorithms behind it.
As you progress, you’ll dive into essential machine learning concepts like gradient descent, decision trees, and convolutional neural networks (CNNs).
This hands-on approach ensures you learn how to work with machine learning algorithms in real-life applications, such as image recognition, language processing, and more.
Course 3: Machine Learning Crash Course by Google
