In digital pathology, input data is often exceedingly too large for DL models to process directly, with Whole Slide Images (WSI) around 100k x 100k pixels. This post provides a quantitative and qualitative method, with code, to help optimize important digital pathology specific hyperparameters: patch size and magnification. Optimizing these variables can decrease training times, lowers hardware requirements, and reduces the amount of data required to effectively train a model.
