    Nov 29, 2021 A common job of machine learning algorithms is to recognize objects and being able to separate them into categories. This process is called classification, and it helps us segregate vast quantities of data into discrete values, i.e. :distinct, like 0/1, True/False, or a pre-defined output label class
