Machine Learning (ML) is the science of getting computers to act without being explicitly programmed. It is the engine behind everything from Netflix recommendations to self-driving cars.
To master ML, you must move beyond just calling .fit() and .predict(). You must understand the intuition and trade-offs of the core algorithms.
1. Linear & Logistic Regression: The Foundations
Linear Regression
Used for predicting continuous values. The goal is to find the 'Line of Best Fit' by minimizing the Mean Squared Error (MSE).
