 # Machine Learning
 
+## Definition
+
 Machine Learning (ML) is a subset of artificial intelligence (AI) that focuses on the development of systems and algorithms that can learn from and make decisions or predictions based on data. The core idea is to enable a machine to make intelligent decisions or predictions without being explicitly programmed to perform the task.
