Discretize

Discretize the input data (continuous) through a multi-level threshold function.

Input values that are below a threshold are mapped to a specifiable constant value (usually 0.0), and values that are above the threshold are mapped to another constant value (usually 1.0). This can be extended to an unlimited number of threshold levels. The new mapped values just need to contain 1 more value than the given number of threshold levels. If you do not specify new values, then 0-based integer values will be used. Version 1.1.0

list (can be None)

newvals

Optional list of of mapped-to values. Values that are smaller than a given threshold will be mapped to the first constant, and values that are larger than or equal to the next threshold will be mapped to the next constant. If given, this list needs to be exactly 1 value longer than the list of threshold cutoff values. If not given, then 0-based integer values will be used. Example: threshold cutoff values = [5, 10]; new values = [0, 1, 2]. All data below 5 will now be 0, data between 5 and 10 will now be 1, data greater than 10 will now be 2.

preserve_dtype

If True, the output data will have the same value type as the input data, i.e ., floats. Note that this may not what you want if you try to map to integer values.
