Mitigating Training Imbalance in LLM Fine-Tuning via Selective Parameter Merging

no code implementations1 Oct 2024 Yiming Ju, Ziyi Ni, Xingrun Xing, Zhixiong Zeng, Hanyu Zhao, Siqi Fan, Zheng Zhang

Supervised fine-tuning (SFT) is crucial for adapting Large Language Models (LLMs) to specific tasks.

A Knowledge-enhanced Two-stage Generative Framework for Medical Dialogue Information Extraction

1 code implementation30 Jul 2023 Zefa Hu, Ziyi Ni, Jing Shi, Shuang Xu, Bo Xu

However, these generative methods output a whole sequence consisting of term-status pairs in one stage and ignore integrating prior knowledge, which demands a deeper understanding to model the relationship between terms and infer the status of each term.

VILAS: Exploring the Effects of Vision and Language Context in Automatic Speech Recognition

no code implementations31 May 2023 Ziyi Ni, Minglun Han, Feilong Chen, Linghui Meng, Jing Shi, Pin Lv, Bo Xu

In this paper, we first propose ViLaS (Vision and Language into Automatic Speech Recognition), a novel multimodal ASR model based on the continuous integrate-and-fire (CIF) mechanism, which can integrate visual and textual context simultaneously or separately, to facilitate speech recognition.

Mixture of personality improved Spiking actor network for efficient multi-agent cooperation

no code implementations10 May 2023 Xiyun Li, Ziyi Ni, Jingqing Ruan, Linghui Meng, Jing Shi, Tielin Zhang, Bo Xu

Inspired by this two-step psychology theory, we propose a biologically plausible mixture of personality (MoP) improved spiking actor network (SAN), whereby a determinantal point process is used to simulate the complex formation and integration of different types of personality in MoP, and dynamic and spiking neurons are incorporated into the SAN for the efficient reinforcement learning.
