Overview
The Swin Transformer was proposed in Swin Transformer: Hierarchical Vision Transformer using Shifted Windows
by Ze Liu, Yutong Lin, Yue Cao, Han Hu, Yixuan Wei, Zheng Zhang, Stephen Lin, Baining Guo. 
The abstract from the paper is the following:
This paper presents a new vision Transformer, called Swin Transformer, that capably serves as a general-purpose backbone 
for computer vision. Challenges in adapting Transformer from language to vision arise from differences between the two domains, 
such as large variations in the scale of visual entities and the high resolution of pixels in images compared to words in text. 
To address these differences, we propose a hierarchical Transformer whose representation is computed with \bold{S}hifted 
\bold{win}dows. The shifted windowing scheme brings greater efficiency by limiting self-attention computation to non-overlapping
