特别是,我们展示了 MSA 和 Vision Transformers (ViT) 的以下属性:1 MSA 不仅提高了准确性,还通过使损失情况变平来提高了泛化能力。这种改进主要归因于它们的数据特异性,而不是远程依赖性。另一方面,ViTs 遭受非凸损失。大型数据集和损失平面平滑方法缓解了这个问题; 2 MSA 和 Convs 表现出相反的行为。例如,MSA...

This is why CNNs and Transformers are tailored for different types of data and tasks. CNNs dominate in the field of computer vision due to their efficiency in processing spatial information, while Transformers are the go-to choice for complex sequential tasks, especially in NLP, due to their ...
本文深入探讨了在训练视觉转换器（Vision Transformers, ViTs）过程中，数据集大小、数据增强、正则化等关键因素的作用与影响。研究结果表明，在小数据集上长时间训练模型，结合适当的正则化手段，可以达到或超越在大数据集上训练的效果。具体案例包括ViT模型在相对较小的ImageNet21k数据集上的表现，甚至能够与...
Vision Transformers(ViT)在图像分类、目标检测和语义图像分割等领域具有很强的竞争力。与卷积神经网络相比,在较小的训练数据集上进行训练时,Vision Transformers较弱的感应偏差通常会导致对模型正则化或数据增强(简称“AugReg”)的依赖性增加。为了更好地理解训练数据量、AugReg、模型大小和计算预算之间的相互作用,我们...
🔬 How Vision Transformers Work Let's go step by step: 1️⃣ Splitting Image into Patches We take an image and break it into small non-overlapping patches. import torch import torchvision.transforms as transforms from PIL import Image # Load and preprocess an image image = Image.open("...
How Do Vision Transformers Work? ICLR 2022·Namuk Park,Songkuk Kim· The success of multi-head self-attentions (MSAs) for computer vision is now indisputable. However, little is known about how MSAs work. We present fundamental explanations to help better understand the nature of MSAs. In ...
