8.4 Introduction to Algorithms

An algorithm is a step-by-step set of instructions. In ML, it's the method a model uses to learn from data.

Chapter 8: Data and AI Algorithms

An algorithm is just a precise list of steps to solve a problem. A recipe is an algorithm. So is the method you use to find a word in a dictionary.

In machine learning, different algorithms suit different problems. Linear regression fits a line to predict numbers. Decision trees ask a series of yes/no questions. K-means groups similar points. Neural networks handle complex patterns.

Choosing an algorithm depends on your data, your goal, how much accuracy you need and whether you need to explain the result.

Key takeaways
