Transformer Branch.Following ViT,该分支包含N个重复的trasnformer block,如图2b所示,每个trasnformer block由一个多头自注意力模块和一个MLP块组成(包含一个向上投影的fc层和一个向下投影的fc层),在自注意力层和MLP块中的每个层和shorcut之前应用LN,对于tokenization,通过一个线性投影层将stem模块生成的特征图压缩为...
The hybrid ViT-SENet framework employs encoders and self-attention networks with squeeze and excitation channel functions to allow precise, robust, fast, and efficient tomato classification. In simulation, the framework achieves a training accuracy of 99.87% and validation accuracy of 93.87%, ...
DPT uses the Vision Transformer (ViT) as backbone and adds a neck + head on top for monocular depth estimation. This repository hosts the “hybrid” version of the model as stated in the paper. DPT-Hybrid diverges from DPT by using ViT-hybrid as a backbone and taking some activations from...

Vision Transformers (ViT) use self-attention, which is a “global” activity since it collects information from the entire image. As a result, the ViT can successfully gather distant semantic relevance from an image. This study examined several optimizers, including Adamax, SGD, RMSprop, Adadelta...
ConViT是基于DeiT的一个开源ViT的超参数优化版本,由于DeiT能够在不适用任何外部数据的情况下获得有竞争力的结果,它既有良好的基线,又相对容易训练,最大的模型DeiT-B只需要在8个GPU上训练几天。为了模拟2x2,3x3,4x4卷积滤波器,考虑三种不同的ConViT模型,他们的注意力头分别4,9,16(见表1.)他们的注意力头数略大...
Vision Transformer(ViT)作为一种有前景的卷积神经网络(CNN)替代方案出现,它利用自注意力层提供扩大的感受野。然而,ViT最初缺乏CNN的一些固有优势,比如归纳偏置和平移不变性,且需要大规模的训练数据集才能达到竞争性的性能。为了解决这些限制,Data-efficient Image Transformer(DeiT)引入了一种基于蒸馏的训练策略,即使在较...
The recent amalgamation of transformer and convolutional designs has led to steady improvements in accuracy and efficiency of the models. In this work, we introduce FastViT, a hybrid vision transformer architecture that obtains the state-of-the-art latency-accuracy trade-off. To this end, we intr...
