Recently I have been working on a new Multiple Instance Learning (MIL) framework that can couple the patch representation learning with the bag-level classification. The process has been pretty hard, since I also have to deal with other businesses at the same time. However, I am still very exc...

I have to admit that pathology data are really hard to deal with.Whole Slide ImagesA pathology dataset contains many Whole Slide Images (WSI). WSIs are designed to be like microscope images. Therefore, it also includes images of different magnificati...

Currently I am working on research related to pathology datasets, and as you may know, these images are usually extremely large. For example, a .tif whole slide image from a Phillips machine can cost me about 2.3G disk space, and remember, remember that it is just ONE SINGLE image. For my path...

Previously I have spent some time researching pure MLP-based segmentation methods. I did find some amazing work that plays all kinds of tricks on MLP, but still, I gave up on segmentation MLPs in the end. Generally speaking, MLPs are not suitable for dense prediction tasks unless some groundbr...

Convolution has become dominant in visual tasks for a very long time. In recent years, people have argued that convolution lacks the ability to model long-range dependencies and propose to use Non-Lcoal operations to make up for this flaw. For example, in CVPR2018, Xiaolong Wang et al. propose...
