Recovering Latent Causal Factor for Generalization to Distributional Shifts

1 code implementation NeurIPS 2021 Xinwei Sun, Botong Wu, Xiangyu Zheng, Chang Liu, Wei Chen, Tao Qin, Tie-Yan Liu

To avoid such a spurious correlation, we propose \textbf{La}tent \textbf{C}ausal \textbf{I}nvariance \textbf{M}odels (LaCIM) that specifies the underlying causal structure of the data and the source of distributional shifts, guiding us to pursue only causal factor for prediction.

Causal Hidden Markov Model for Time Series Disease Forecasting

no code implementations CVPR 2021 Jing Li, Botong Wu, Xinwei Sun, Yizhou Wang

We propose a causal hidden Markov model to achieve robust prediction of irreversible disease at an early stage, which is safety-critical and vital for medical treatment in early stages.

Forecasting Irreversible Disease via Progression Learning

no code implementations CVPR 2021 Botong Wu, Sijie Ren, Jing Li, Xinwei Sun, Shiming Li, Yizhou Wang

In order to account for the degree of progression of the disease, we propose a temporal generative model to accurately generate the future image and compare it with the current one to get a residual image.

Identifying Invariant Texture Violation for Robust Deepfake Detection

no code implementations19 Dec 2020 Xinwei Sun, Botong Wu, Wei Chen

To learn such an invariance for deepfake detection, our InTeLe introduces an auto-encoder framework with different decoders for pristine and fake images, which are further appended with a shallow classifier in order to separate out the obvious artifact-effect.

Latent Causal Invariant Model

no code implementations4 Nov 2020 Xinwei Sun, Botong Wu, Xiangyu Zheng, Chang Liu, Wei Chen, Tao Qin, Tie-Yan Liu

To avoid spurious correlation, we propose a Latent Causal Invariance Model (LaCIM) which pursues causal prediction.

Learning With Unsure Data for Medical Image Diagnosis

no code implementations ICCV 2019 Botong Wu, Xinwei Sun, Lingjing Hu, Yizhou Wang

The benefits of learning with unsure data and validity of our models are demonstrated on the prediction of Alzheimer's Disease and lung nodules.

Joint Learning for Pulmonary Nodule Segmentation, Attributes and Malignancy Prediction

no code implementations10 Feb 2018 Botong Wu, Zhen Zhou, Jianwei Wang, Yizhou Wang

Refer to the literature of lung nodule classification, many studies adopt Convolutional Neural Networks (CNN) to directly predict the malignancy of lung nodules with original thoracic Computed Tomography (CT) and nodule location.

Zero-Shot Learning posed as a Missing Data Problem

no code implementations2 Dec 2016 Bo Zhao, Botong Wu, Tianfu Wu, Yizhou Wang

This paper presents a method of zero-shot learning (ZSL) which poses ZSL as the missing data problem, rather than the missing label problem.
