An LLM-based Simulation Framework for Embodied Conversational Agents in Psychological Counseling

AAAI 2026technical

Due to privacy concerns, open dialogue datasets for mental health are primarily generated through human or AI synthesis methods. However, the inherent implicit nature of psychological processes, particularly those of clients, poses challenges to the authenticity and diversity of synthetic data. In t

Optimizing Speech Multi-View Feature Fusion through Conditional Computation

ICASSP 2025accepted

Recent advancements have highlighted the efficacy of self-supervised learning (SSL) features in various speech-related tasks, providing lightweight and versatile multi-view speech representations. However, our study reveals that while SSL features expedite model convergence, they conflict with tradi…

Generalizable Whole Slide Image Classification with Fine-Grained Visual-Semantic Interaction

CVPR 2024poster

Whole Slide Image (WSI) classification is often formulated as a Multiple Instance Learning (MIL) problem. Recently Vision-Language Models (VLMs) have demonstrated remarkable performance in WSI classification. However existing methods leverage coarse-grained pathogenetic descriptions for visual repre…

Self-adaptive Extreme Penalized Loss for Imbalanced Time Series Prediction

IJCAI 2024poster

Forecasting time series in imbalanced data presents a significant research challenge that requires considerable attention. Although there are specialized techniques available to tackle imbalanced time series prediction, existing approaches tend to prioritize extreme predictions at the expense of com…

Modality Adaption or Regularization? A Case Study on End-to-End Speech Translation

ACL 2023short

Pre-training and fine-tuning is a paradigm for alleviating the data scarcity problem in end-to-end speech translation (E2E ST). The commonplace ”modality gap” between speech and text data often leads to inconsistent inputs between pre-training and fine-tuning. However, we observe that this gap occur…

Unsupervised Paraphrasing under Syntax Knowledge

AAAI 2023technical

The soundness of syntax is an important issue for the paraphrase generation task. Most methods control the syntax of paraphrases by embedding the syntax and semantics in the generation process, which cannot guarantee the syntactical correctness of the results. Different from them, in this paper we…
