Definition and Key Concepts

Machine Learning is a branch of AI that focuses on building systems that learn from and adapt to data without being explicitly programmed. Unlike traditional software that follows pre-defined rules, ML algorithms improve their performance as they are exposed to more data over time.

Key concepts in ML include:

  1. Training data: The initial dataset used to teach the algorithm
  2. Features: The input variables used by the model
  3. Labels: The output or prediction the model is trying to produce
  4. Model: The mathematical representation of the real-world process

Types of ML Algorithms

There are three main types of ML algorithms:

  1. Supervised Learning: The algorithm learns from labeled data to predict outcomes for new, unseen data. Examples include linear regression and decision trees.
  2. Unsupervised Learning: The algorithm finds patterns in unlabeled data. Clustering algorithms are a common example.
  3. Reinforcement Learning: The algorithm learns by interacting with an environment and receiving feedback on its actions.
