Study Notes
Definitions and Concepts
- Machine learning is defined as a subset of artificial intelligence where systems learn from data.
- Tom Mitchell describes it in terms of the ability of a computer to learn from experience.
Purpose of Machine Learning
- The main purpose is to enable computers to make predictions or decisions based on data.
- Machine learning techniques are used to automate complex processes and improve accuracy over time.
Well-posed Problem Definition
- A 'well-posed' mathematical definition of machine learning includes clearly defined tasks, performance measures, and learning from data.
- The definition implies that the machine should generalize from training data to unseen instances.
Main Applications of Machine Learning
- Major applications include but are not limited to image recognition, natural language processing, recommendation systems, and autonomous driving.
- These applications leverage trained models to handle varied and high-dimensional data.
Checkers Learning Problem
- The task in the checkers example involves playing the game of checkers at a competitive level.
- Performance measures can include winning games, number of moves saved, or overall win-loss ratio against opponents.
Learning Objective
- The goal of using machine learning in such tasks is to adapt strategies based on past game outcomes, improving future decision-making.
