Implementation 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 out for everyone so we ...

Let L denote the cross entropy loss of an image-label pair (x, y). We are interested in the gradient of L w.r.t. x, and move x in the direction of (the sign of) the gradient to increase L. If L becomes large, the new image x_adv will likely be misclassified. We use chain...
Creating the nine labels reduced the head-pose problem into a simple image classification task (that is, using an image as input, estimating one head pose out of nine). The model is fine-tuned from a ResNet-50 that we obtained from the MXNet model zoo. There are five main par...

In this article, we will do a text classification using Keras which is a Deep Learning Python Library. Why Keras? There are many deep learning frameworks available in the market like TensorFlow, Theano. So why do I prefer Keras? Well, the most important reason is its Simplicity. Keras is ...
ColorNet: Investigating the importance of color spaces for image classification 总结 这是一篇讨论不同颜色空间(color space) 对于分类任务(classification)精度影响的文章。 文中介绍了RGB、LAB、YCrCb、HSV、CIE等等不同的颜色空间,在单一颜色空间上进行分类任务使用LAB颜色空间精度最高 文中做了实验,证明同一个任...
