Clustering

Clustering is concerned with grouping a set of objects to distribute them into groups of similar objects. Also known as cluster analysis, this is a set of techniques and algorithms that intends to group similar objects, producing clusters. The simplest illustrative introduction would be grouping a set of colored objects into different groups consisting of objects of the same color, as follows:

Although we are discussing AI tasks in this chapter, we suggest that you first try to solve problems with the knowledge base that you have so far. Let’s think about how we would categorize objects by similarity. First of all, we should have a basic idea of what the object will look like. In the preceding example, we are looking at an object’s shape, color, dimensions (the width and height of a 2D object), and so on. Without going much deeper, a basic representation of an object might look like this:
