Grounding Multi-Hop Reasoning in Structural Causal Models via Group Relative Policy Optimization

ICML 2026poster

Multi-Hop Fact Verification (MHFV) necessitates complex reasoning across disparate evidence, posing significant challenges for Large Language Models (LLMs) which often suffer from hallucinations and fractured logical chains. Existing methods, while improving transparency via Chain-of-Thought (CoT), …

MT-HUBERT: SELF-SUPERVISED MIX-TRAINING FOR FEW-SHOT KEYWORD SPOTTING IN MIXED SPEECH

ICASSP 2026oral

Few-shot keyword spotting aims to detect previously unseen keywords with very limited labeled samples. A pre-training and adaptation paradigm is typically adopted for this task. While effective in clean conditions, most existing approaches struggle with mixed keyword spotting--detecting multiple ove…

Towards Efficient Semi-Supervised Semantic Segmentation for Solid-State LiDAR Point Clouds

ICRA 2026poster

LiDAR-based 3D semantic segmentation is a critical task in autonomous driving, but its scalability is limited by the reliance on large-scale labeled datasets. Semi-supervised learning (SSL) offers a potential solution by leveraging unlabeled data. However, most existing SSL segmentation methods are …

MSACC: A Unified Multimodal Sentiment Analysis Framework for High Interpretability and Zero-shot Performance

ICASSP 2025accepted

Compared to large language models, traditional multimodal sentiment analysis frameworks are constrained by their classification heads, resulting in poor performance on zero-shot tasks. Moreover, due to limitations in visual encoders and multimodal fusion modules, most existing frameworks can only pr…

Cross-Modal Alignment for End-to-End Spoken Language Understanding Based on Momentum Contrastive Learning

ICASSP 2024accepted

The end-to-end spoken language understanding system extracts the semantic intent directly from an input speech. It effectively avoids problems such as semantic drift in traditional cascade models. However, the lack of semantically labeled speech data makes the model training process diffi-cult. Seve…
