New MedTokenBudget framework prioritizes lesion regions in dermoscopic image classification

Researchers have developed MedTokenBudget, a novel framework for dermoscopic image classification that prioritizes lesion regions. This supervised post-backbone token routing system learns to create compact representations by focusing on lesion-enriched patches, especially when auxiliary lesion masks are available. The Lesion-Aware Token Scoring (LATS) module within MedTokenBudget fuses attention entropy, feature norm, and local feature contrast to identify and route the most diagnostically relevant patches under a specified budget. Evaluations on the ISIC 2019 dataset demonstrate that mask-supervised LATS outperforms existing methods like Random and ToMe in retaining lesion evidence while adhering to token budgets. AI

IMPACT This approach could improve the efficiency and accuracy of AI models used in medical image analysis by focusing computational resources on diagnostically critical areas.
