An Empirical Analysis on Large Language Models in Debate Evaluation

1 code implementation28 May 2024 Xinyi Liu, Pinxin Liu, Hangfeng He

In this study, we investigate the capabilities and inherent biases of advanced large language models (LLMs) such as GPT-3. 5 and GPT-4 in the context of debate evaluation.

Adaptive Super Resolution For One-Shot Talking-Head Generation

1 code implementation23 Mar 2024 Luchuan Song, Pinxin Liu, Guojun Yin, Chenliang Xu

In this work, we propose an adaptive high-quality talking-head video generation method, which synthesizes high-resolution video without additional pre-trained modules.
