(CNNs) to focus more on an image's global context instead of local information, which greatly improves the performance of CNNs. However, we found it to have limited benefits for transformer-based architectures that naturally have a global receptive field. In this paper, we propose a novel ...
该项目名为「vit-pytorch」,它是一个 Vision Transformer 实现,展示了一种在 PyTorch 中仅使用单个 transformer 编码器来实现视觉分类 SOTA 结果的简单方法。 项目当前的 star 量已经达到了 7.5k,创建者为 Phil Wang,ta 在 GitHub 上有 147 个资源库。
代码和模型 https://github.com/google-research/vision_transformer VisionTransformer 将输入图像视为一系列图块,类似于自然语言处理 (NLP) Transformer 生成的一系列词嵌入 Vision Transformer Transformer 将文本中一系列单词作为输入,然后将其用于分类、翻译或其他 NLP 任务。对于 ViT,我们尽量避免修改 Transformer...
Transformer block for images:Multi-head Self Attention layers 之后往往会跟上一个 Feed-Forward Network (FFN) ,它一般是由2个linear layer构成,第1个linear layer把维度从维变换到维,第2个linear layer把维度从维再变换到维。 此时的Transformer block是不考虑位置信息的,即一幅图片只要内容不变,patches的顺序...
Using a standard encoder-decoder transformer, we find that captioning alone is surprisingly effective: on classification tasks, captioning produces vision encoders competitive with contrastively pretrained encoders, while surpassing them on vision & language tasks. We further analyze the effect of the ...
