Self-Supervised Learning Achieves 99.64% Accuracy in Brain Tumor MRI Classification

ai-technology · 2026-05-06

A recent research paper on arXiv (2605.01999) presents TumorXAI, an innovative self-supervised learning (SSL) framework aimed at explainable classification of brain tumors from MRI images. Researchers employed a ResNet-50 backbone to assess SimCLR, BYOL, DINO, and MoCo v3 using a public dataset consisting of 4,448 MRIs representing 17 different tumor types. Notably, SimCLR reached an impressive accuracy, precision, recall, and F1-score of 99.64%. The methodology encompasses preprocessing, fine-tuning, linear evaluation, and SSL pretraining with various augmentations. When labels were scarce, SSL-pretrained models surpassed traditional supervised baselines. Additionally, the framework offers visual insights into the decisions made by the model.
