HSViT: Horizontally Scalable Vision Transformer

2 code implementations8 Apr 2024 Chenhao Xu, Chang-Tsun Li, Chee Peng Lim, Douglas Creighton

While the Vision Transformer (ViT) architecture gains prominence in computer vision and attracts significant attention from multimedia communities, its deficiency in prior knowledge (inductive bias) regarding shift, scale, and rotational invariance necessitates pre-training on large-scale datasets.

An Efficient and Reliable Asynchronous Federated Learning Scheme for Smart Public Transportation

1 code implementation15 Aug 2022 Chenhao Xu, Youyang Qu, Tom H. Luan, Peter W. Eklund, Yong Xiang, Longxiang Gao

Asynchronous Federated Learning (AFL) is a scheme that reduces the latency of aggregation to improve efficiency, but the learning performance is unstable due to unreasonably weighted local models.
