Classifiers

BetweenClassifier	A boolean classifier that checks if a value is within a specified range.
BoolClassifier	Abstract base class for classifiers with a boolean verdict.
Categorizer	Abstract base class for classifiers that assign each value to a bin.
Classifier	Abstract base class for all data quality classifiers.
DoesNotMatch	A boolean classifier that checks whether a value does not match a regular expression.
ExponentialScale	A scale whose bin edges are spaced exponentially over [min_val, max_val] (used with ScaleCategorizer).
HasLength	A boolean classifier that checks whether a value's length is within a range.
IdentityScale	A scale where every integer in [min_val, max_val) maps to its own bin (used with ScaleCategorizer).
InClassifier	A boolean classifier that checks if a value is in a specified set of values.
IsBetween	A boolean classifier that checks whether a value is inside a range.
IsFalse	A boolean classifier that checks whether a value is False.
IsIn	A boolean classifier that checks whether a value is in a set of values.
IsNan	A boolean classifier that checks whether a value is NaN (not a number).
IsNegative	A boolean classifier that checks whether a numeric value is negative.
IsNegativeOrZero	A boolean classifier that checks whether a numeric value is negative or zero.
IsNotBetween	A boolean classifier that checks whether a value is outside a range.
IsNotIn	A boolean classifier that checks whether a value is not in a set of values.
IsNotNan	A boolean classifier that checks whether a value is not NaN.
IsNotNull	A boolean classifier that checks whether a value is not null.
IsNotNullNorNan	A boolean classifier that checks whether a value is neither null nor NaN.
IsNotZero	A boolean classifier that checks whether a numeric value is not zero.
IsNull	A boolean classifier that checks whether a value is null.
IsNullOrNan	A boolean classifier that checks whether a value is null or NaN.
IsPositive	A boolean classifier that checks whether a numeric value is positive.
IsPositiveOrZero	A boolean classifier that checks whether a numeric value is positive or zero.
IsTrue	A boolean classifier that checks whether a value is True.
IsZero	A boolean classifier that checks whether a numeric value is zero.
LinearScale	A scale that splits [min_val, max_val] into equal-width bins (used with ScaleCategorizer).
LogarithmicScale	A scale whose bin edges are spaced logarithmically over [min_val, max_val] (used with ScaleCategorizer).
MatchClassifier	A boolean classifier that checks if a value matches a regex pattern.
Matches	A boolean classifier that checks whether a value matches a regular expression.
MonomialScale	A power-law scale over [min_val, max_val] whose bin widths grow as a power of the value (used with ScaleCategorizer).
Scale	Abstract base class for the scales used by ScaleCategorizer.
ScaleCategorizer	A classifier that assigns each value to a bin defined by a Scale.
