Entity Enhanced BERT Pre-training for Chinese NER

no code implementations EMNLP 2020 Chen Jia, Yuefeng Shi, Qinrong Yang, Yue Zhang

We then integrate the entity information into BERT using Char-Entity-Transformer, which augments the self-attention using a combination of character and entity representations.

Gender Bias in Large Language Models across Multiple Languages

no code implementations1 Mar 2024 Jinman Zhao, Yitian Ding, Chen Jia, Yining Wang, Zifan Qian

We investigate the outputs of the GPT series of LLMs in various languages using our three measurement methods.

Generalizing Reward Modeling for Out-of-Distribution Preference Learning

no code implementations22 Feb 2024 Chen Jia

During meta-training, a bilevel optimization algorithm is utilized to learn a reward model capable of guiding policy learning to align with human preferences across various distributions.

Bilevel Optimization Meta-Learning +1

Discrepancy-Optimal Meta-Learning for Domain Generalization

no code implementations29 Sep 2021 Chen Jia

This work attempts to tackle the problem of domain generalization (DG) via learning to reduce domain shift with an episodic training procedure.

Steady-state joint distribution for first-order stochastic reaction kinetics

no code implementations9 Feb 2021 Youming Li, Da-Quan Jiang, Chen Jia

Here we develop a novel method of computing the exact joint distributions of a wide class of first-order stochastic reaction systems in steady-state conditions.

Small protein number effects in stochastic models of autoregulated bursty gene expression

no code implementations8 Jan 2020 Chen Jia, Ramon Grima

Furthermore we show that our model predictions for the protein number distribution are significantly different from those of Kumar et al. when the protein mean is small, gene switching is fast, and protein binding is faster than unbinding.

Exact power spectrum in a minimal hybrid model of stochastic gene expression oscillations

no code implementations21 Sep 2019 Chen Jia, Hong Qian, Michael Q. Zhang

In our model, oscillations tend to occur when the protein is relatively stable and when gene switching is relatively slow.
