Time-CoT: Hierarchical Reasoning with Temporal Semantic Codes for Multivariate Time Series Classification

ICML 2026poster

Integrating Large Language Models (LLMs) into time series tasks has yielded impressive performance. While some works aim to enhance accuracy by explicitly designing step-by-step reasoning into prompts, such explicit Chain-of-Thought (CoT) approaches are difficult to generalize to time series. This i…

LLM-Enhanced Query Generation and Retrieval Preservation for Task-Oriented Dialogue

ACL 2025finding

Knowledge retrieval and response generation are fundamental to task-oriented dialogue systems. However, dialogue context frequently contains noisy or irrelevant information, leading to sub-optimal result in knowledge retrieval. One possible approach to retrieving knowledge is to manually annotate st…

WaveSpect: A Hybrid Approach to Synthetic Audio Detection via Waveform and Spectrogram Analysis

ICASSP 2025accepted

With the rapid advancement of synthetic speech technology, the challenges posed by audio deepfakes have become increasingly severe. Despite notable progress in synthetic speech detection, existing algorithms exhibit limited generalization to unknown attacks. To address these challenges, we propose W…

SPGNet: A Shape-prior Guided Network for Medical Image Segmentation

IJCAI 2024poster

Given the intricacy and variability of anatomical structures in medical images, some methods employ shape priors to constrain segmentation. However, limited by the representational capability of these priors, existing approaches often struggle to capture diverse target structure morphologies. To add…

Unsupervised Domain Adaptive Salient Object Detection through Uncertainty-Aware Pseudo-Label Learning

AAAI 2022technical

Recent advances in deep learning significantly boost the performance of salient object detection (SOD) at the expense of labeling larger-scale per-pixel annotations. To relieve the burden of labor-intensive labeling, deep unsupervised SOD methods have been proposed to exploit noisy labels generated…
