Introduction to Machine Learning

Comments 205 Comments

Machine Learning (ML) is a subfield of artificial intelligence (AI) that focuses on the development of algorithms and models that allow computers to learn from data and make predictions or decisions without being explicitly programmed for every task. The primary goal of machine learning is to develop algorithms that can learn patterns and relationships from data and use this knowledge to make predictions or decisions on new, unseen data. Imagine a dataset containing information about students’ attendance records, study hours…
