iNews: A Multimodal Dataset for Modeling Personalized Affective Responses to News

no code implementations5 Mar 2025 Tiancheng Hu, Nigel Collier

Current approaches to emotion detection often overlook the inherent subjectivity of affective experiences, instead relying on aggregated labels that mask individual variations in emotional responses.

Efficient Long-Decoding Inference with Reasoning-Aware Attention Sparsity

no code implementations16 Feb 2025 Junhao Hu, Wenrui Huang, Weidong Wang, Zhenwen Li, Tiancheng Hu, Zhixia Liu, Xusheng Chen, Tao Xie, Yizhou Shan

For example, the state-of-the-art algorithm, Quest, achieves high accuracy with $O(L)$ time but $O(N)$ memory ($L$ is the cache budget, $L \ll N$).

Can LLM be a Personalized Judge?

1 code implementation17 Jun 2024 Yijiang River Dong, Tiancheng Hu, Nigel Collier

Ensuring that large language models (LLMs) reflect diverse user values and preferences is crucial as their user bases expand globally.

The Potential and Challenges of Evaluating Attitudes, Opinions, and Values in Large Language Models

no code implementations16 Jun 2024 Bolei Ma, Xinpeng Wang, Tiancheng Hu, Anna-Carolina Haensch, Michael A. Hedderich, Barbara Plank, Frauke Kreuter

This paper aims to bridge this gap by providing a comprehensive overview of recent works on the evaluation of AOVs in LLMs.

Can Language Models Recognize Convincing Arguments?

no code implementations31 Mar 2024 Paula Rescala, Manoel Horta Ribeiro, Tiancheng Hu, Robert West

The capabilities of large language models (LLMs) have raised concerns about their potential to create and propagate convincing narratives.

Quantifying the Persona Effect in LLM Simulations

1 code implementation16 Feb 2024 Tiancheng Hu, Nigel Collier

Notably, we find a linear relationship in our setting: the stronger the correlation between persona variables and human annotations, the more accurate the LLM predictions are using persona prompting.

Generative Language Models Exhibit Social Identity Biases

no code implementations24 Oct 2023 Tiancheng Hu, Yara Kyrychenko, Steve Rathje, Nigel Collier, Sander van der Linden, Jon Roozenbeek

The surge in popularity of large language models has given rise to concerns about biases that these models could learn from humans.

Drug Re-positioning via Text Augmented Knowledge Graph Embeddings

no code implementations NeurIPS Workshop AI4Scien 2021 Mian Zhong, Tiancheng Hu, Ying Jiao, Shehzaad Zuzar Dhuliawala, Bipin Singh

Drug re-positioning, modeled as a link prediction problem over medical knowledge graphs (KG), has great potential in finding new usage or targets for approved medicine with relatively low cost.

The Multimodal Driver Monitoring Database: A Naturalistic Corpus to Study Driver Attention

no code implementations23 Dec 2020 Sumit Jha, Mohamed F. Marzban, Tiancheng Hu, Mohamed H. Mahmoud, Naofal Al-Dhahir Carlos Busso

We use the Fi- Cap device that continuously tracks the head movement of the driver using fiducial markers, providing frame-based annotations to train head pose algorithms in naturalistic driving conditions.
