CMQA: A Dataset of Conditional Question Answering with Multiple-Span Answers

1 code implementation COLING 2022 Yiming Ju, Weikang Wang, Yuanzhe Zhang, Suncong Zheng, Kang Liu, Jun Zhao

To bridge the gap, we propose a new task: conditional question answering with hierarchical multi-span answers, where both the hierarchical relations and the conditions need to be extracted.

Discontinuous phase transition of feature detection in lateral predictive coding

no code implementations21 Jan 2025 Zhen-Ye Huang, Weikang Wang, Hai-Jun Zhou

The brain adopts the strategy of lateral predictive coding (LPC) to construct optimal internal representations for salient features in input sensory signals to reduce the energetic cost of information transmission.

Beyond Complete Shapes: A quantitative Evaluation of 3D Shape Matching Algorithms

no code implementations5 Nov 2024 Viktoria Ehm, Nafie El Amrani, Yizheng Xie, Lennart Bastian, Maolin Gao, Weikang Wang, Lu Sang, Dongliang Cao, Zorah Lähner, Daniel Cremers, Florian Bernard

While approaches based on machine learning dominate modern 3D shape matching, almost all existing (learning-based) methods require that at least one of the involved shapes is complete.

Cell phenotypic transition proceeds through concerted reorganization of gene regulatory network

no code implementations8 Jul 2021 Weikang Wang, Dante Poe, Ke Ni, Jianhua Xing

Phenotype transition takes place in many biological processes such as differentiation, and understanding how a cell reprograms its global gene expression profile is a problem of rate theories.

DS-Net: Dynamic Spatiotemporal Network for Video Salient Object Detection

1 code implementation9 Dec 2020 Jing Liu, Jiaxiang Wang, Weikang Wang, Yuting Su

In this paper, we investigate the complimentary roles of spatial and temporal information and propose a novel dynamic spatiotemporal network (DS-Net) for more effective fusion of spatiotemporal information.
