This repo contains code examples that demonstrate how to use cleanlab and how confident learning works to find label errors.
To quickly learn the basics of running cleanlab on your own data, we recommend first starting here before diving into the examples below.
Recommended order of examples to try:
| Example | Description | |
|---|---|---|
| 1 | iris_simple_example.ipynb | Use cleanlab to find synthetic label errors in the Iris dataset. |
| 2 | classifier_comparison.ipynb | Demonstrate how cleanlab can be used to train 10 different classifiers on 4 dataset distributions with label errors. |
| 3 | model_selection_demo.ipynb | Perform hyperparameter optimization to find the best settings of cleanlab's optional parameters. |
| 4 | simplifying_confident_learning_tutorial.ipynb | Implement cleanlab as raw numpy code. |
| 5 | visualizing_confident_learning.ipynb | Demonstrate how cleanlab performs noise matrix estimation. |
| 6 | cifar10-cnn-coteaching | Demonstrate the use of two experimental modules from cleanlab: cifar_cnn.py and coteaching.py |
| 7 | mnist-cnn | Demonstrate the use of the following experimental module from cleanlab: mnist_pytorch.py |
| 8 | amazon-reviews-fasttext | Demonstrate the use of the following experimental module from cleanlab: fasttext.py |
To run the latest example notebooks, execute the commands below which will install the required libraries in a virtual environment.
It is recommended to run the examples with the latest stable cleanlab release. See requirements.txt file.
$ python -m pip install virtualenv
$ python -m venv env
$ source env/bin/activate
$ python -m pip install -r requirements.txtFor examples 1-5, you may run the notebooks individually or run the bash script below which will execute and save each notebook.
Bash script:
$ bash ./run_all_notebooks.shFor examples 6-8, please follow the instructions in the README of each folder.
See the contrib folder for examples from v1 of cleanlab which may be helpful for reproducing results from the Confident Learning paper.
