Cleanlab

Cleanlab is a data-centric AI library and toolkit designed to improve machine learning model performance by detecting label errors and increasing overall dataset quality. It implements a confident learning framework that iteratively refines label noise estimates by comparing model predictions with estimated label probabilities to identify mislabeled examples.

The project provides specialized utilities for active learning optimization, allowing for the selection of the most impactful examples for labeling or re-labeling. It also includes an outlier detection tool to identify atypical data points and anomalies that fall outside expected distributions.

Additional capabilities cover dataset quality analysis, including the assessment of annotator reliability through consensus measurement and the calculation of class-level issues. The library also supports noise-robust model training to maintain accuracy when training data contains incorrect labels.

Features

  • Confident Learning Label Cleaning - Locates mislabeled examples using confident learning algorithms to improve overall data quality.
  • Class-Conditional Noise Modeling - Models the probability of labels being flipped between classes to quantify dataset-wide noise levels.
  • Dataset Health Analysis - Calculates class-level issues and generates quality summaries to determine if a dataset is reliable for training.
  • Dataset Label Error Detection - Finds and corrects mislabeled examples in training data using confident learning to improve model accuracy.
