Machine learning

Machine learning (ML) is a branch of artificial intelligence (AI) that focuses on building systems that can learn from data, identify patterns, and make decisions with minimal human intervention. Here’s a quick breakdown depending on your interest level: --- 🔹 Basic Definition : Machine Learning is when computers learn from data to make predictions or decisions without being explicitly programmed. --- 🔹 Types of Machine Learning: 1 . Supervised Learning Learns from labeled data (input + correct output) Example: Predicting house prices, email spam detection Algorithms: Linear Regression, Decision Trees, Support Vector Machines, etc. 2. Unsupervised Learning Finds hidden patterns in unlabeled data Example: Customer segmentation, anomaly detection Algorithms: K-Means, Hierarchical Clustering, PCA 3. Reinforcement Learning An agent learns by interacting with an environment, receiving rewards or penalties Example: Game-playing AI (like AlphaGo), robotics Algorithms: Q-learning, Deep Q-N...
