Introduction to Machine Learning
Learn the key ideas behind machine learning—training data, features, models, and evaluation—so you can understand how predictions are made, what the model is actually learning, and where those predictions fail.
See How Machine Learning Turns Data Into Predictions
Machine learning is not a computer somehow finding the right answer on its own. It is a structured process of choosing data, defining useful features, training a model for a particular task, and checking how well it handles examples it has not seen.
You will build that mental model before worrying about advanced math. Along the way, you will compare learning types, see why generalization matters, use evaluation metrics in context, and recognize the data and bias problems that can make a model look better than it is.
What You'll Learn
"Frame a Machine-Learning Problem" is the starting point; "Evaluate Results and Failure Modes" is where the pieces come together.
Frame a Machine-Learning Problem
Define the prediction, the available examples, and the real decision the model is meant to support.
Choose Features, Labels, and a Learning Type
Separate inputs from targets and distinguish supervised, unsupervised, regression, and classification work.
Understand Training and Generalization
See how a model fits patterns in training data and why performance on unseen examples matters more than memorization.
Evaluate Results and Failure Modes
Use data splits and metrics in context while checking bias, weak data, and behavior outside the training conditions.
