fatf.fairness.data.measures.systemic_bias_check(systemic_bias_matrix: numpy.ndarray) → bool

Indicates whether a dataset has a systemic bias.

Parameters

systemic_bias_matrixnumpy.ndarray

A square (equal number of rows and columns) boolean numpy array that indicates which pair of data points share the same unprotected features but differ in protected features and ground truth annotation. (The number of rows/columns should be equal to the number of data points in the original data set.)

Returns

systemic_bias_presentboolean

True if systemic bias is present, False otherwise.

Raises

IncorrectShapeError

The systemic bias matrix is not 2-dimensional or square.

TypeError

The systemic bias matrix is not of boolean type.

ValueError

The systemic bias matrix is a structured numpy array or is not diagonally symmetric.
