Labeled Images for Ulcerative Colitis (LIMUC) Dataset
<h1><strong>Dataset Details</strong></h1> <p>The LIMUC dataset compromises 11276 images from 564 patients and 1043 colonoscopy procedures, who underwent colonoscopy for ulcerative colitis between December 2011 and July 2019 at the Department of Gastroenterology in Marmara University School of Medicine. Two experienced gastroenterologists blindly reviewed and classified all images according to the Mayo endoscopic score (MES). Images that were differently labeled by two reviewers were also labeled by a third experienced reviewer independently without seeing their previous labels. The final MES for differently labeled images was determined using majority voting.</p> <p><br><strong>Mayo 0:</strong> 6105 (54.14%)<br><strong>Mayo 1:</strong> 3052 (27.70%)<br><strong>Mayo 2:</strong> 1254 (11.12%)<br><strong>Mayo 3:</strong> 865 (7.67%)</p> <p><strong>patient_based_classified_images:</strong> Images of each patient are separated according to Mayo classes. If a train-val-test splitting is to be made according to the ratios desired by the user, this folder should be used.</p> <p><strong>train_and_validation_sets:</strong> Train and validation sets used in the <a href="https://academic.oup.com/ibdjournal/advance-article-abstract/doi/10.1093/ibd/izac226/6830946">research paper</a>. Using the scripts in dataset's GitHub repository, same 10-fold can be generated for replicating the results.</p> <p><strong>test_set:</strong> Test set used for performance measurement in the research paper. For a fair performance comparisons, this should be used to report performances.</p> <h1><strong>Suggested Metrics</strong></h1> <p>Since there are imbalances and ordinality among classes (Mayo-0, Mayo-1, Mayo-2, Mayo-3), quadratic weighted kappa (QWK) can be used as the main performance metric. The QWK is one of the commonly used statistics for the assessment of agreement on an ordinal scale and it is one of the best singular performance metrics for this problem regarding class imbalances. Mean absolute error (MAE), macro F1 score, or macro accuracy can be used as alternative performance metrics.</p> <h1><strong>LIMUC Code Repository</strong></h1> <p>Many scripts for preprocessing, splitting, training, and validating the dataset are provided in <a href="https://github.com/GorkemP/labeled-images-for-ulcerative-colitis">this</a> GitHub repository.</p> <h1><strong>Terms and Conditions</strong></h1> <p>The LIMUC dataset is licensed under the <strong>Creative Commons Attribution 4.0 International (CC BY 4.0)</strong> license.
