MACHINE LEARNING OVERVIEW
Machine learning (ML) is a subfield of artificial intelligence (AI) that focuses on developing
algorithms and models that enable computers to learn from data and make predictions or decisions
without explicit programming. It involves the use of statistical techniques and mathematical models to
enable systems to improve their performance on a specific task over time. Below is a detailed
overview of various aspects of machine learning:
, 1. Types of Machine Learning:
- Supervised Learning:
- Involves training a model on a labeled dataset.
- The algorithm learns a mapping from input features to the corresponding target labels.
- Examples include linear regression, support vector machines, and neural networks.
- Unsupervised Learning:
- Deals with unlabeled data where the algorithm identifies patterns, relationships, or structures.
- Clustering and dimensionality reduction are common tasks in unsupervised learning.
- Examples include k-means clustering and principal component analysis (PCA).
- Semi-Supervised Learning:
- Utilizes a combination of labeled and unlabeled data for training.
- It aims to improve model performance by leveraging both types of data.
- Reinforcement Learning:
- Involves an agent learning to make decisions by interacting with an environment.
- The agent receives feedback in the form of rewards or penalties.
- Examples include Q-learning and deep reinforcement learning with neural networks.
