What is Machine Learning (ML)?
Machine Learning (ML) is a subset of AI that enables computers to learn from data and improve their performance over time without being explicitly programmed. It focuses on building algorithms that identify patterns and make predictions or decisions based on input data.

Full Definition
Machine Learning (ML) is a branch of artificial intelligence focused on developing algorithms and statistical models that allow computers to perform specific tasks by learning from data, rather than following explicitly programmed instructions. ML systems use training data to identify patterns, make decisions, and improve their performance autonomously over time.
There are several types of machine learning: supervised learning, where models are trained on labeled data; unsupervised learning, which finds hidden patterns in unlabeled data; and reinforcement learning, where models learn through trial and error to maximize a reward signal. ML techniques power applications such as spam detection, image and speech recognition, recommendation systems, and predictive analytics.
Implementing ML effectively requires high-quality data, appropriate model selection, and continuous evaluation to avoid pitfalls such as overfitting, underfitting, and bias. ML is integral to the advancement of AI, enabling systems to adapt dynamically and solve complex problems.
