StableVC: Style Controllable Zero-Shot Voice Conversion with Conditional Flow Matching

no code implementations6 Dec 2024 Jixun Yao, Yuguang Yan, Yu Pan, Ziqian Ning, Jiaohao Ye, Hongbin Zhou, Lei Xie

Zero-shot voice conversion (VC) aims to transfer the timbre from the source speaker to an arbitrary unseen speaker while preserving the original linguistic content.

Doubly Robust Causal Effect Estimation under Networked Interference via Targeted Learning

1 code implementation6 May 2024 Weilin Chen, Ruichu Cai, Zeqin Yang, Jie Qiao, Yuguang Yan, Zijian Li, Zhifeng Hao

Based on the condition, we devise an end-to-end causal effect estimator by transforming the identified theoretical condition into a targeted loss.

Debiased Model-based Interactive Recommendation

no code implementations24 Feb 2024 Zijian Li, Ruichu Cai, Haiqin Huang, Sili Zhang, Yuguang Yan, Zhifeng Hao, Zhenghua Dong

Existing model-based interactive recommendation systems are trained by querying a world model to capture the user preference, but learning the world model from historical logged data will easily suffer from bias issues such as popularity bias and sampling bias.

Identifying Semantic Component for Robust Molecular Property Prediction

1 code implementation8 Nov 2023 Zijian Li, Zunhong Xu, Ruichu Cai, Zhenhui Yang, Yuguang Yan, Zhifeng Hao, Guangyi Chen, Kun Zhang

Specifically, we first formulate the data generation process from the atom level to the molecular level, where the latent space is split into SI substructures, SR substructures, and SR atom variables.

Generalization bound for estimating causal effects from observational network data

no code implementations8 Aug 2023 Ruichu Cai, Zeqin Yang, Weilin Chen, Yuguang Yan, Zhifeng Hao

To fill this gap, we derive a generalization bound for causal effect estimation in network scenarios by exploiting 1) the reweighting schema based on joint propensity score and 2) the representation learning schema based on Integral Probability Metric (IPM).

Siamese Encoder-based Spatial-Temporal Mixer for Growth Trend Prediction of Lung Nodules on CT Scans

1 code implementation7 Jun 2022 Jiansheng Fang, Jingwen Wang, Anwei Li, Yuguang Yan, Yonghe Hou, Chao Song, Hongbo Liu, Jiang Liu

In the management of lung nodules, we are desirable to predict nodule evolution in terms of its diameter variation on Computed Tomography (CT) scans and then provide a follow-up recommendation according to the predicted result of the growing trend of the nodule.

Weighing Features of Lung and Heart Regions for Thoracic Disease Classification

no code implementations26 May 2021 Jiansheng Fang, Yanwu Xu, Yitian Zhao, Yuguang Yan, Junling Liu, Jiang Liu

By zeroing features of non-lung and heart regions in attention maps, we can effectively exploit their disease-specific cues in lung and heart regions.

Combating Ambiguity for Hash-code Learning in Medical Instance Retrieval

1 code implementation19 May 2021 Jiansheng Fang, Huazhu Fu, Dan Zeng, Xiao Yan, Yuguang Yan, Jiang Liu

When encountering a dubious diagnostic case, medical instance retrieval can help radiologists make evidence-based diagnoses by finding images containing instances similar to a query case from a large image database.
