incerto.active.VarianceRatioAcquisition

class incerto.active.VarianceRatioAcquisition(num_samples=20)

Bases: BaseAcquisition

Variance ratio acquisition.

Measures disagreement as: 1 - (mode_count / num_samples)

num_samples (int)

__init__(num_samples=20)

Initialize variance ratio acquisition.

Parameters:

num_samples (int) – Number of samples for estimation

Methods

__init__([num_samples])	Initialize variance ratio acquisition.
score(model, x, **kwargs)	Compute variance ratio scores.
