Machine learning is a subset of artificial intelligence (AI) focused on developing algorithms and models that enable computers to learn from and make decisions based on data. Instead of being explicitly programmed for each task, machine learning systems improve their performance over time as they are exposed to more data.
Machine learning is related to AI in that it is one of the primary methods used to achieve intelligent behavior in machines. While AI encompasses a broader range of techniques and approaches aimed at creating systems that can perform tasks requiring human-like intelligence, machine learning specifically deals with the aspect of learning from data to improve and adapt.
