Machine Learning

 Machine Learning is a branch of Artificial Intelligence that enables computers to learn from data and improve their performance without being explicitly programmed . Why Do We Need Machine Learning? Traditional programming works well when rules are fixed. But real-world problems are complex and dynamic. Machine learning helps when: Data is huge Patterns are complex Rules change frequently Examples: Email spam detection Face recognition Product recommendations Weather prediction Types of Machine Learning 1️⃣ Supervised Learning The model learns from labeled data (input + correct output). Examples: Predicting marks based on study hours Email spam classification Common algorithms: Linear Regression Decision Tree Support Vector Machine 2️⃣ Unsupervised Learning The model works with unlabeled data and finds hidden patterns. Examples: Customer segmentation Grouping similar documents Common algorithms: K-Means Clustering Hie...
