class Pearson

Bases: PlibEvaluatorMixin

Pearson correlation coefficient.

Measures the linear relationship predictions and ground truth. Strictly speaking, Pearson’s correlation assumes that outputs be normally distributed.

evaluate(predictions, true_values)

Base evaluation function.

Parameters:

• predictions (ndarray[Any, dtype[TypeVar(_ScalarType_co, bound= generic, covariant=True)]]) – predictions of the model to be evaluated

• true_values (PlibData) – true values to evaluate predictions on

Return type:

float

Returns:

evaluation score
