QueryCraft: Transformer-Guided Query Initialization for Enhanced Human-Object Interaction Detection

AAAI 2026technical

Human-Object Interaction (HOI) detection aims to localize human-object pairs and recognize their interactions in images. Although DETR-based methods have recently emerged as the mainstream framework for HOI detection, they still suffer from a key limitation: Randomly initialized queries lack explici

What-Meets-Where: Unified Learning of Action and Contact Localization in Images

AAAI 2026technical

People control their bodies to establish contact with the environment. To comprehensively understand actions across diverse visual contexts, it is essential to simultaneously consider what action is occurring and where it is happening. Current methodologies, however, often inadequately capture this

LLM Agents Can Be Choice-Supportive Biased Evaluators: An Empirical Study

AAAI 2025technical

With Large Language Model (LLM) agents taking on more evaluation responsibilities in decision-making, it is essential to recognize their possible biases to guarantee fair and trustworthy AI-supported decisions. This study is the first to thoroughly examine the choice-supportive bias in LLM agents, a…

Precision-Enhanced Human-Object Contact Detection via Depth-Aware Perspective Interaction and Object Texture Restoration

AAAI 2025technical

Human-object contact (HOT) is designed to accurately identify the areas where humans and objects come into contact. Current methods frequently fail to account for scenarios where objects are frequently blocking the view, resulting in inaccurate identification of contact areas. To tackle this problem…

Prompt Guidance and Human Proximal Perception for HOT Prediction with Regional Joint Loss

ICCV 2025poster

The task of Human-Object conTact (HOT) detection involves identifying the specific areas of the human body that are touching objects. Nevertheless, current models are restricted to just one type of image, often leading to too much segmentation in areas with little interaction, and struggling to main…

Pyramidal Flow Matching for Efficient Video Generative Modeling

ICLR 2025poster

Video generation requires modeling a vast spatiotemporal space, which demands significant computational resources and data usage. To reduce the complexity, the prevailing approaches employ a cascaded architecture to avoid direct training with full resolution latent. Despite reducing computational de…

Harder Task Needs More Experts: Dynamic Routing in MoE Models

ACL 2024long

In this paper, we introduce a novel dynamic expert selection framework for Mixture of Experts (MoE) models, aiming to enhance computational efficiency and model performance by adjusting the number of activated experts based on input difficulty. Unlike existing MoE approaches that rely on fixed TopK…

Fast Intent Classification for Spoken Language Understanding Systems

ICASSP 2020accepted

Spoken Language Understanding (SLU) systems consist of several machine learning components operating together (e.g. intent classification, named entity recognition and resolution). Deep learning models have obtained state of the art results on several of these tasks, largely attributed to their bett…
