Vision Transformer - PytorchImplementation of Vision Transformer, a simple way to achieve SOTA in vision classification with only a single transformer encoder, in Pytorch. Significance is further explained in Yannic Kilcher's video. There's really not much to code here, but may as well lay it ...
第1篇是针对Transformer模型处理图片的方式:将输入图片划分成一个个块(patch),然后将这些patch看成一个块的序列 (Sequence)的不完美之处,提出了一种TNT架构,它不仅考虑patch之间的信息,还考虑每个patch的内部信息,使得Transformer模型分别对整体和局部信息进行建模,提升性能。 对本文符号进行统一: Multi-head Self-atte...

ViT,DeiT,IPT,SETR,ViT-FRCNN到这里就把它们输入Transformer了,本文为了更好地学习图片中global和local信息的关系,还要再进行一步: 接下来再把每个patch通过PyTorch的unfold操作划分成更小的patch,之后把这些小patch展平,就得到了 \begin{equation} \mathcal{Y}_0=[Y_0^1,Y_0^2,\cdots,Y_0^n]\in\...
Vision Transformer from Scratch This is a simplified PyTorch implementation of the paperAn Image is Worth 16x16 Words: Transformers for Image Recognition at Scale. The goal of this project is to provide a simple and easy-to-understand implementation. The code is not optimized for speed and is ...
Vision Transformer implementation from scratch using the PyTorch deep learning library and training it on the ImageNet dataset. Learn self-attention mechanism.
Transformer是一个Sequence to Sequence model,特别之处在于它大量用到了self-attention。 要处理一个Sequence,最常想到的就是使用RNN,它的输入是一串vector sequence,输出是另一串vector sequence,如下图1左所示。 如果假设是一个single directional的RNN,那当输出 时,默认 都已经看过了。如果假设是一个bi-directiona...
所以作者这里设计了一种Transformer in Transformer (TNT)的结构,第1步还是将输入图片划分成个块(patch): 式中是每个块的大小。ViT,DeiT,IPT,SETR,ViT-FRCNN到这里就把它们输入Transformer了,本文为了更好地学习图片中global和local信息的关系,还要再进行一步:接下来再把每个patch通过PyTorch的unfold操作划分成更小...
