Reduced-Order Autodifferentiable Ensemble Kalman Filters

1 code implementation27 Jan 2023 Yuming Chen, Daniel Sanz-Alonso, Rebecca Willett

This paper introduces a computational framework to reconstruct and forecast a partially observed state that evolves according to an unknown or expensive-to-simulate dynamical system.

Towards Spatial Equilibrium Object Detection

1 code implementation14 Jan 2023 Zhaohui Zheng, Yuming Chen, Qibin Hou, Xiang Li, Ming-Ming Cheng

In this paper, we study the spatial disequilibrium problem of modern object detectors and propose to quantify this ``spatial bias'' by measuring the detection performance over zones.

Extracting and Measuring Uncertain Biomedical Knowledge from Scientific Statements

no code implementations5 Dec 2021 Xin Guo, Yuming Chen, Jian Du, Erdan Dong

Design/methodology/approach: Taking cardiovascular research publications in China as a sample, we extracted the SPO triples as knowledge unit and the hedging/conflicting uncertainties as the knowledge context.

Auto-differentiable Ensemble Kalman Filters

1 code implementation16 Jul 2021 Yuming Chen, Daniel Sanz-Alonso, Rebecca Willett

Data assimilation is concerned with sequentially estimating a temporally-evolving state.
