:class:`.Discretizer` can be used to discretize continuous data. `self.bins` is a list of values starting with the smallest possible value and ending with the largest possible value. All intervals in between are bins, e.g. when `discretize(self,value)` is called the index of the bin that `value` falls in is returned.
