An overview of machine learning

ML is a variegated field with many different types of algorithms that try to learn in slightly different ways. We can divide them into the following different categories according to the way the algorithm performs the learning:

• Supervised learning
• Unsupervised learning
• Semi-supervised learning
• Reinforcement learning

In this book, we are going to touch on each single category, but the main focus will be supervised learning. We are going to briefly introduce these categories and the type of problems that they help solve.
