Module evaluate 

Progressive (prequential) evaluation.

The evaluation order is fixed:

predict → metric.update → learn

This ensures each prediction is made before the model sees the current sample, giving an honest estimate of generalization on streaming data.

Structs

BinaryClassificationSample

A single binary classification sample.

ProgressiveStep

A single step of progressive evaluation, recording the prediction made before learning from this sample.

RegressionSample

A single regression sample.

Functions

evaluate_binary_classification

Run progressive evaluation on a binary classification stream.

evaluate_regression

Run progressive evaluation on a regression stream.

evaluate_regression_with_steps

Like evaluate_regression but also collects per-step records.
