QuesRecAgent: A Dual-Loop Multi-Agent Question Recommender for Enhancing Knowledge Mastery

IJCAI 2026

Adaptive Learning Systems (ALS) play a key role in promoting the equity of education, which can provide personalized teaching on a large scale. However, the existing question recommendation methods face the problem of data sparsity at the scenario of cold-start, and lack the ability of long-term tea

R4Det: 4D Radar-Camera Fusion for High-Performance 3D Object Detection

CVPR 2026

4D radar-camera sensing configuration has gained increasing importance in autonomous driving. However, existing 3D object detection methods that fuse 4D Radar and camera data confront several challenges. First, their absolute depth estimation module is not robust and accurate enough, leading to inac

SEMAMIL: SEMANTIC-AWARE MULTIPLE INSTANCE LEARNING WITH RETRIEVAL-GUIDED STATE SPACE MODELING FOR WHOLE SLIDE IMAGES

ICASSP 2026poster

Multiple instance learning (MIL) has become the leading approach for extracting discriminative features from whole slide images (WSIs) in computational pathology. Attention-based MIL methods can identify key patches but tend to overlook contextual relationships. Transformer models are able to model…

Shift-Dependent Asymmetry: Orthogonal Inverse Low-Rank Adaptation for Federated Medical Segmentation

ICML 2026poster

Low-Rank Adaptation (LoRA) enables efficient federated fine-tuning of segmentation foundation models for medical imaging. However, most federated LoRA methods adopt a uniform aggregation rule, which breaks under the encoder–decoder asymmetry in medical segmentation: the encoder is dominated by appea…

DS-BTIAN: A Novel Deep-Shallow Bidirectional Transformer Interactive Attention Network for Multimodal Emotion Recognition

ICASSP 2025accepted

In this work, we propose a novel Deep-Shallow Bidirectional Transformer Interactive Attention Network (DS-BTIAN) designed for robust multimodal emotion recognition. DS-BTIAN leverages pre-trained Wav2Vec2.0 and BERT models for efficient feature extraction without the need for finetuning, enhancing r…

Domain-Specific Pruning of Large Mixture-of-Experts Models with Few-shot Demonstrations

NeurIPS 2025poster

Mixture-of-Experts (MoE) models achieve a favorable trade-off between performance and inference efficiency by activating only a subset of experts. However, the memory overhead of storing all experts remains a major limitation, especially in large-scale MoE models such as DeepSeek-R1 (671B). In this…

VasTSD: Learning 3D Vascular Tree-state Space Diffusion Model for Angiography Synthesis

CVPR 2025poster

Angiography imaging is a medical imaging technique that enhances the visibility of blood vessels within the body by using contrast agents. Angiographic images can effectively assist in the diagnosis of vascular diseases. However, contrast agents may bring extra radiation exposure which is harmful to…

Visual Prompting in LLMs for Enhancing Emotion Recognition

EMNLP 2024main

Vision Large Language Models (VLLMs) are transforming the intersection of computer vision and natural language processing; however, the potential of using visual prompts for emotion recognition in these models remains largely unexplored and untapped. Traditional methods in VLLMs struggle with spatia…
