Constraint

Supported linear constraints in ReHLine are listed in the table below.

Usage

# list of
# name (str): name of the custom linear constraints
# loss_kwargs: more keys and values for constraint parameters
constraint = [{'name': <constraint_name>, <**constraint_kwargs>}, ...]

constraint	args	Example
nonnegative	name: 'nonnegative' or '>=0'	constraint=[{'name': '>=0'}]
fair	name: 'fair' or 'fairness' sen_idx: a list contains column indices for sensitive attributes tol_sen: 1d array [p] of tolerance for fairness	constraint=[{'name': 'fair', 'sen_idx': sen_idx, 'tol_sen': tol_sen}]
monotonic	name: 'monotonic' or 'monotonicity' decreasing (bool): False (default)	constraint=[{'name': 'monotonic', 'decreasing': True}]
custom	name: 'custom' A: 2d array [K x d] for linear constraint coefficients b: 1d array [K] of constraint intercepts	constraint=[{'name': 'custom', 'A': A, 'b': b}]
