Find Dataset-level Issues for Dataset Curation#

This tutorial shows how cleanlab.dataset.health_summary() helps you automatically:

  • Score and rank the overall label quality of each class, useful for deciding whether to remove or keep certain classes.

  • Identify overlapping classes that you can merge to make the learning task less ambiguous.

  • Generate an overall dataset and label quality health score to track improvements in your labels over time as you clean your datasets.

Install dependencies and import them#

You can use pip to install all packages required for this tutorial as follows:

!pip install requests
!pip install cleanlab
# Make sure to install the version corresponding to this tutorial
# E.g. if viewing master branch documentation:
#     !pip install git+https://github.com/cleanlab/cleanlab.git

[2]:

import requests
import io
import cleanlab
import numpy as np
