Embracing Uncertainty: Decoupling and De-bias for Robust Temporal Grounding

no code implementations CVPR 2021 Hao Zhou, Chongyang Zhang, Yan Luo, Yanjun Chen, Chuanping Hu

Meanwhile, modified feature assigned with style-like words (including adjectives, adverbs, etc) represents the subjective information, and thus brings personalized predictions; De-bias - We propose a de-bias mechanism to generate diverse predictions, aim to alleviate the bias caused by single-style annotations in the presence of label uncertainty.

Dynamical instabilities for model with point-coupling interactions: Vlasov formalism method

no code implementations14 Dec 2020 Yanjun Chen, Juan Zou, Zipeng Cheng, Binguang He

We explore the effects of the density dependence of symmetry energy on the dynamical instabilities and crust-core phase transition in the cold and warm neutron stars in the RMF theory with point-coupling interactions using the Vlasov approach.
