Machine Unlearning via Adaptive Gradient Reweighting and Multi-stage Objective Optimization

CVPR 2026

Machine Unlearning (MU) focuses on removing the influence of training samples from pre-trained models without retraining the model entirely. Existing MU methods have made several efforts to enable complete forgetting while preserving the model's performance on remaining data. However, they typically

Synergizing LLMs with Global Label Propagation for Multimodal Fake News Detection

ACL 2025long

Large Language Models (LLMs) can assist multimodal fake news detection by predicting pseudo labels. However, LLM-generated pseudo labels alone demonstrate poor performance compared to traditional detection methods, making their effective integration non-trivial. In this paper, we propose Global Labe…

FedVAD: Enhancing Federated Video Anomaly Detection with GPT-Driven Semantic Distillation

ECCV 2024poster

"The imperative for smart surveillance systems to robustly detect anomalies poses a unique challenge given the sensitivity of visual data and privacy concerns. We propose a novel Federated Learning framework for Video Anomaly Detection that operates under the constraints of data heterogeneity and pr…

Hierarchical Speaker Representation for Target Speaker Extraction

ICASSP 2024accepted

Target speaker extraction aims to isolate a specific speaker’s voice from a composite of multiple sound sources, guided by an enrollment utterance or called anchor. Current methods predominantly derive speaker embeddings from the anchor and integrate them into the separation network to separate the…

C2ST: Cross-Modal Contextualized Sequence Transduction for Continuous Sign Language Recognition

ICCV 2023poster

Continuous Sign Language Recognition (CSLR) aims to transcribe the signs of an untrimmed video into written words or glosses. The mainstream framework for CSLR consists of a spatial module for visual representation learning, a temporal module aggregating the local and global temporal information of…

Alleviating the Loss-Metric Mismatch in Supervised Single-Channel Speech Enhancement

ICASSP 2022accepted

In this paper, we study the loss-metric mismatch problem of supervised single-channel speech enhancement system. Most of the existing speech enhancement systems achieve unsatisfying performance since their empirically selected loss functions have semantic gaps with the non-differentiable evaluation…

Dual Adversarial Graph Neural Networks for Multi-label Cross-modal Retrieval

AAAI 2021technical

Cross-modal retrieval has become an active study field with the expanding scale of multimodal data. To date, most existing methods transform multimodal data into a common representation space where semantic similarities between items can be directly measured across different modalities. However, the…
