Class DemographicParityBiasDetector<T>

Namespace

AiDotNet.Interpretability

Assembly

AiDotNet.dll

Detects bias using Demographic Parity (Statistical Parity Difference). Measures the difference in positive prediction rates between groups. A difference greater than 0.1 (10%) indicates potential bias.

Constructors

DemographicParityBiasDetector(double)

Initializes a new instance of the DemographicParityBiasDetector class.

public DemographicParityBiasDetector(double threshold = 0.1)

Parameters

threshold double

The threshold for detecting bias (default is 0.1, representing 10% difference threshold).
