calibrator 0.0.13

A package for calibration on deep learning models for classification tasks.

Calibration

a python package for calibrating the deep learning models

Install

pip install calibrator

Use case

from calibrator import LocalCalibrator
import torch

val_logits = torch.randn(1000, 10)
val_labels = torch.randint(0, 10, (1000,))
test_logits = torch.randn(1000, 10)

calibrator = LocalCalibrator()
eps_opt = calibrator.fit(val_logits, val_labels)
calibrated_probability = calibrator.calibrate(test_logits)
