Rethinking Multiple Instance Learning for Whole Slide Image Classification: A Good Instance Classifier is All You Need

no code implementations5 Jul 2023 Linhao Qu, Yingfan Ma, Xiaoyuan Luo, Manning Wang, Zhijian Song

In this paper, we propose an instance-level MIL framework based on contrastive learning and prototype learning to effectively accomplish both instance classification and bag classification tasks.

The Rise of AI Language Pathologists: Exploring Two-level Prompt Learning for Few-shot Weakly-supervised Whole Slide Image Classification

1 code implementation NeurIPS 2023 Linhao Qu, Xiaoyuan Luo, Kexue Fu, Manning Wang, Zhijian Song

Our approach incorporates the utilization of GPT-4 in a question-and-answer mode to obtain language prior knowledge at both the instance and bag levels, which are then integrated into the instance and bag level language prompts.

Bi-directional Weakly Supervised Knowledge Distillation for Whole Slide Image Classification

1 code implementation7 Oct 2022 Linhao Qu, Xiaoyuan Luo, Manning Wang, Zhijian Song

Specifically, an attention-based bag classifier is used as the teacher network, which is trained with weak bag labels, and an instance classifier is used as the student network, which is trained using the normalized attention scores obtained from the teacher network as soft pseudo labels for the instances in positive bags.

A Learnable Self-supervised Task for Unsupervised Domain Adaptation on Point Clouds

no code implementations12 Apr 2021 Xiaoyuan Luo, Shaolei Liu, Kexue Fu, Manning Wang, Zhijian Song

In the UDA architecture, an encoder is shared between the networks for the self-supervised task and the main task of point cloud classification or segmentation, so that the encoder can be trained to extract features suitable for both the source and the target domain data.
