Types of learning algorithms

Let's now discuss more about machine learning and machine learning algorithms. Broadly speaking, there are three types of machine learning algorithms: supervised learning, unsupervised learning, and reinforcement learning. Let's first learn how these three different types of machine learning algorithms differ from each other:

• Supervised learning algorithms: These algorithms are used when the prediction target or outcome is known. For example, if we want to use machine learning to predict who will make purchases in the next few days, then we will use supervised learning algorithms. Here, the prediction target or outcome is whether this person made a purchase within the given time window or not. Based on the historical ...
