Machine Learning

Introduction to Machine Learning

Machine Learning (ML) is a subset of AI that focuses on developing algorithms and models that enable machines to learn from data and make predictions or decisions without human intervention. It involves training machines on a vast amount of data and allowing them to learn patterns, relationships, and insights within the data.

Supervised Learning

Supervised learning is a technique in machine learning where machines are trained using labeled data, meaning data that is already labeled or classified. The machine learns from the labeled data and can then make predictions or classify new, unseen data based on what it has learned. Some common algorithms used in supervised learning include Linear Regression, Decision Trees, and Support Vector Machines.

Unsupervised Learning

Unsupervised learning, on the other hand, involves training machines using unlabeled data. The goal is to discover hidden patterns or structures within the data without any prior knowledge or labels. Clustering and dimensionality reduction techniques, such as K-means clustering and Principal Component Analysis (PCA), are commonly used in unsupervised learning.

Reinforcement Learning

Reinforcement Learning (RL) is a type of machine learning where an agent learns to interact with an environment to maximize rewards or minimize penalties. The agent explores the environment by taking actions and receives feedback in the form of rewards or punishments. It uses this feedback to learn which actions lead to desirable outcomes. RL is commonly used in applications like gaming, robotics, and autonomous systems.

Deep Learning
