"Whole slide images are graphs": Our paper on effectiveness of graph modelling of WSIs in & Graph Neural Networks ( ) for receptor status prediction of from routine WSIs is accepted in Medical Image Analysis.
See: https://arxiv.org/abs/2110.06042
TL;DR
Motivation: Whole slide images are big and holistic modelling of interactions between different tissue components using only slide level labels is difficult with conventional "patch-then-aggregate" approaches used for weakly supervised learning in CPath.
2. We introduce a flexible based framework ( +) that can holistically model WSIs for different large scale prediction problems
3. For HER2 status prediction, the method gives AUC 0.75-0.8 and can be used for case triaging & advanced ordering of tests
4. To demonstrate the flexibility of SlideGraph, our implementation uses different local features For ER status predictionwith an AUC of 0.88
5. Once you extract local features, the method is lightning fast allowing large scale experiments (

Unless appropriately trained, or models in Computational Pathology can be fragile to natural or adversarial subvisual perturbations. Our paper presents Robustness Evaluation and Enhancement Toolbox (R**T) for to help address this challenge.
TL;DR
1/R**T provides a suite of algorithmic strategies for enabling robustness assessment of a trained predictive model with respect to specialized image transformations such as staining, compression, focusing/blurring, changes in spatial resolution, etc.
2/R**T enables efficient and robust training of pipelines by providing a custom implementation of Adversarial Training for Free.
