Foundations of Data Science for Machine Learning
From the most basic classical machine learning models, to exploratory data analysis and customizing architectures, you’ll be guided by easy to digest conceptual content and interactive Jupyter notebooks, all without leaving your browser.
Foundations of Data Science for Machine Learning is the complete learning path and the recommended option for most people. It has all the same modules as the learning paths Understand Data Science for Machine Learning and Create Machine Learning Models with a custom flow that maximizes reinforcement of concepts.
If you want to learn about both the underlying concepts as well as how to get into building models with the most common machine learning tools this is the path for you. It's also the best path if you plan to move beyond classic machine learning, and get an education in deep learning and neural networks, which we only introduce here.

2) Build Classical Machine Learning Models with Supervised Learning
Supervised learning is a form of machine learning where an algorithm learns from examples of data. We progressively paint a picture of how supervised learning automatically generates a model that can make predictions about the real world. We also touch on how these models are tested, and difficulties that can arise in training them.
In this module, you will:
In this module, you will:
- Define supervised and unsupervised learning.
- Explore how cost functions affect the learning process.
- Discover how models are optimized by gradient descent.
- Experiment with learning rates, and see how they can affect training.
3) Introduction to Data for Machine Learning
The power of machine learning models comes from the data that is used to train them. Through content and exercises, we explore how to understand your data, how to encode it so that the computer can interpret it properly, how to clean it of errors, and tips that will help you create models that perform well.
