Adaptive Multi-Scale Local Correction for Semi-Supervised 3D Medical Image Segmentation

ICASSP 2025accepted

In recent years, semi-supervised 3D medical image segmentation has gained significant attention. However, current methods often struggle with multi-scale voxel differences and overlook the importance of loss weight balancing. To address these issues, we propose an adaptive multi-scale local correcti…

Continual Unsupervised Domain Adaptation for Audio Deepfake Detection

ICASSP 2025accepted

Audio deepfake detection (ADD) aims to verify the authenticity of audio. However, its performance declines sharply when facing significant domain discrepancies caused by unknown datasets. Unsupervised domain adaptation (UDA) has been applied to mitigate domain mismatch. However, as generative models…

SSR-GPCsT: Deep Learning Models Based on Functional Connectivity Maps in Autism Research

ICASSP 2024accepted

Autism is a neurodevelopmental disorder characterized by difficulties in social interaction, communication, and sensory sensitivity. Functional magnetic resonance imaging (fMRI) is a commonly used brain imaging technique to obtain functional connectivity information in individuals with autism. Howev…

Self-Supervised Domain Exploration with an Optimal Transport Regularization for Open Set Cross-Domain Speech Emotion Recognition

ICASSP 2024accepted

In the tasks of domain adaptation (DA) for speech emotion recognition (SER), self-supervised learning (SSL) algorithms could effectively explore domain and structural information from target domain samples, thereby mitigating domain discrepancies. However, in a general setting, when the target domai…

Optimal Transport with a Diversified Memory Bank for Cross-Domain Speaker Verification

ICASSP 2023accepted

Optimal transport (OT) can be applied to cross-domain adaptation in speaker verification (SV) by converting speakers' probability distributions from source to target domains. However, in scenarios involving over-massive categories (speakers) or difficult samples in discrimination, OT often has diffi…

CS-REP: Making Speaker Verification Networks Embracing Re-Parameterization

ICASSP 2022accepted

Automatic speaker verification (ASV) systems, which determine whether two speeches are from the same speaker, mainly focus on verification accuracy while ignoring inference speed. However, in real applications, both inference speed and verification accuracy are essential. This study proposes cross-s…

Double Noise Mean Teacher Self-Ensembling Model for Semi-Supervised Tumor Segmentation

ICASSP 2022accepted

Accurate tumor segmentation of tumor images can assist doctors to diagnose diseases. However, achieving very high precision in tumor segmentation requires a large amount of annotated data, which is not easy for medical image data. In this paper, we present a novel double noise mean teacher self-ense…

Zero-Shot Voice Conversion with Adjusted Speaker Embeddings and Simple Acoustic Features

ICASSP 2021accepted

Zero-shot voice conversion (VC) where both source and target speakers are unseen in the training dataset has become a new research direction. Using speaker embeddings instead of one-hot vectors to represent speaker identity is a key point, which makes VC models work on unseen speakers. In our work,…
