A Proposal of Dymamic Optimization for Vision Transformer

Abstract (in Japanese) (See Japanese page) 
(in English) In this study, we focus on the Vision Transformer (ViT), which extends the Transformer architecture—originally achieving breakthrough results in natural language processing—to the image domain. While ViT is effective for tasks such as image classification, its performance is highly dependent on large-scale training data and tends to degrade when trained on small datasets. To improve the computational efficiency of Vision Transformers, this study proposes a hybrid architecture that combines Gated Positional Self-Attention (GPSA) with dynamic token pruning based on Proximal Policy Optimization (PPO). Through experiments on CIFAR-10 at 224×224 resolution, we aim to achieve substantial FLOPs reduction while maintaining accuracy by jointly learning the gating mechanism and pruning ratio.
