Machine learning is a type of software that enables computers to learn and improve from experience without being explicitly programmed. It uses algorithms and statistical models to analyze and identify patterns in data, and then uses those patterns to make predictions or decisions. Machine learning is used in a variety of applications, including image and speech recognition, natural language processing, fraud detection, and recommendation systems. It is a rapidly growing field with many potential applications in industries such as healthcare, finance, and transportation. Machine learning is constantly evolving and improving, with new techniques and algorithms being developed all the time.
