IdentityScale

class

class IdentityScale(
    min_val: ScaleIdentityLimitSpec,
    max_val: ScaleIdentityLimitSpec,
    use_bin_zero: bool = False,
)

Bases: Scale

Categories: dq-classifier

A scale where every integer in [min_val, max_val) maps to its own bin (used with ScaleCategorizer).

Examples

One bin per whole value in the range -- here a bin for each score from 1 to 5:

ScaleCategorizer(["score"], scale=IdentityScale(1, 5))

Parameters

parameter

min_valScaleIdentityLimitSpec (StrictInt)

Lowest integer of the scale; a whole number.

parameter

max_valScaleIdentityLimitSpec (StrictInt)

Highest integer of the scale; a whole number strictly greater than min_val and no more than 100 above it (the span is the bin count).

parameter

use_bin_zerobool

If False, the minimum value belongs to the first bin; if True, min_val gets its own bin 0.

Properties

property

binsint

The number of bins, derived from the (min, max) range.
