Machine Learning (ML) is a branch of artificial intelligence (AI) that focuses on building systems capable of learning and improving from experience.Algorithms can be categorized into Supervised Learning, Unsupervised Learning, Semi-Supervised Learning, and Reinforcement Learning.Supervised learning algorithms learn from labeled datasets, meaning each data point is paired with the correct output.Key algorithms in classification include Naive Bayes, Logistic Regression, K-Nearest Neighbor (KNN), and more.
