Unsupervised machine learning algorithm

Unsupervised learning is a machine learning model that finds the hint in the unlabeled data.

So, in the previous example to identify what the circle is, what the triangle is, and what the square is, it looks at the dimensions of the figure or preferably it looks together at the number of corners. Several models have three corners, two corners, one corner or no corners and the model labels a filter to true altogether.
