Vision Transformer architecture enhances medical image classification with Evolutionary Algorithm-based components.
Abstract
The content introduces the Improved EATFormer, a Vision Transformer for Medical Image Classification. It discusses the need for accurate medical image analysis and the limitations of traditional approaches. The EATFormer architecture combines Convolutional Neural Networks and Vision Transformers to improve prediction speed and accuracy. Key components include Enhanced EA-based Transformer block, Global and Local Interaction, Multi-Scale Region Aggregation modules, and Modulated Deformable MSA module. Experimental results on Chest X-ray and Kvasir datasets demonstrate significant improvements over baseline models. The paper also explores the ViT model's features like patch-based processing, positional context incorporation, and Multi-Head Attention mechanism.
