Machine learning is a vital subset of artificial intelligence (AI) that focuses on developing algorithms enabling computers to learn from data, make predictions, and enhance their performance over time. As data continues to grow exponentially, machine learning has become essential for automating processes and deriving insights. The fundamentals of machine learning encompass key concepts such as supervised and unsupervised learning, feature engineering, model selection, and evaluation. Supervised learning involves training algorithms on labeled data, while unsupervised learning identifies patterns in unlabeled data. Understanding these principles is crucial for anyone looking to explore the world of machine learning and AI.
