Statistical learning, also known as machine learning, is a branch of artificial intelligence that deals with the development of algorithms that can learn from and make predictions or decisions based on data. These algorithms use statistical methods to identify patterns in data and make informed decisions or predictions without being explicitly programmed. Statistical learning is widely used in a variety of fields, including finance, healthcare, and marketing, to analyze data and make predictions or classifications. Some common techniques used in statistical learning include linear regression, logistic regression, decision trees, support vector machines, and neural networks.
