Benchmarking a Benchmark: How Reliable is MS-COCO?

no code implementations5 Nov 2023 Eric Zimmermann, Justin Szeto, Jerome Pasquero, Frederic Ratle

Benchmark datasets are used to profile and compare algorithms across a variety of tasks, ranging from image classification to segmentation, and also play a large role in image pretraining algorithms.

Mitigating Calibration Bias Without Fixed Attribute Grouping for Improved Fairness in Medical Imaging Analysis

no code implementations4 Jul 2023 Changjian Shui, Justin Szeto, Raghav Mehta, Douglas L. Arnold, Tal Arbel

However, models that are well calibrated overall can still be poorly calibrated for a sub-population, potentially resulting in a clinician unwittingly making poor decisions for this group based on the recommendations of the model.

Rethinking Generalization: The Impact of Annotation Style on Medical Image Segmentation

no code implementations31 Oct 2022 Brennan Nichyporuk, Jillian Cardinell, Justin Szeto, Raghav Mehta, Jean-Pierre R. Falet, Douglas L. Arnold, Sotirios A. Tsaftaris, Tal Arbel

This is particularly important in the context of medical image segmentation of pathological structures (e. g. lesions), where the annotation process is much more subjective, and affected by a number underlying factors, including the annotation protocol, rater education/experience, and clinical aims, among others.

Cohort Bias Adaptation in Aggregated Datasets for Lesion Segmentation

no code implementations2 Aug 2021 Brennan Nichyporuk, Jillian Cardinell, Justin Szeto, Raghav Mehta, Sotirios Tsaftaris, Douglas L. Arnold, Tal Arbel

Many automatic machine learning models developed for focal pathology (e. g. lesions, tumours) detection and segmentation perform well, but do not generalize as well to new patient cohorts, impeding their widespread adoption into real clinical contexts.

Lesion Segmentation

Optimizing Operating Points for High Performance Lesion Detection and Segmentation Using Lesion Size Reweighting

no code implementations27 Jul 2021 Brennan Nichyporuk, Justin Szeto, Douglas L. Arnold, Tal Arbel

There are many clinical contexts which require accurate detection and segmentation of all focal pathologies (e. g. lesions, tumours) in patient images.

Accounting for Variance in Machine Learning Benchmarks

no code implementations1 Mar 2021 Xavier Bouthillier, Pierre Delaunay, Mirko Bronzi, Assya Trofimov, Brennan Nichyporuk, Justin Szeto, Naz Sepah, Edward Raff, Kanika Madan, Vikram Voleti, Samira Ebrahimi Kahou, Vincent Michalski, Dmitriy Serdyuk, Tal Arbel, Chris Pal, Gaël Varoquaux, Pascal Vincent

Strong empirical evidence that one machine-learning algorithm A outperforms another one B ideally calls for multiple trials optimizing the learning pipeline over sources of variation such as data sampling, data augmentation, parameter initialization, and hyperparameters choices.
