This document provides a gentle introduction to machine learning and AI. It discusses how machine learning works by training algorithms on large datasets to recognize patterns without being explicitly programmed. Examples are given of how machine learning is used in applications like image recognition, speech recognition, and machine translation. The recent rise of machine learning is driven by the abundance of big data from many online sources and the availability of affordable computing power like GPUs. The future of machine learning is unpredictable but areas like quantum computing may further advance the field.
