Exploring Pathological Speech Quality Assessment with ASR-Powered Wav2Vec2 in Data-Scarce Context

no code implementations29 Mar 2024 Tuan Nguyen, Corinne Fredouille, Alain Ghio, Mathieu Balaguer, Virginie Woisard

Automatic speech quality assessment has raised more attention as an alternative or support to traditional perceptual clinical evaluation.

A Class-aware Optimal Transport Approach with Higher-Order Moment Matching for Unsupervised Domain Adaptation

no code implementations29 Jan 2024 Tuan Nguyen, Van Nguyen, Trung Le, He Zhao, Quan Hung Tran, Dinh Phung

Additionally, we propose minimizing class-aware Higher-order Moment Matching (HMM) to align the corresponding class regions on the source and target domains.

Towards Efficient Communication and Secure Federated Recommendation System via Low-rank Training

1 code implementation8 Jan 2024 Ngoc-Hieu Nguyen, Tuan-Anh Nguyen, Tuan Nguyen, Vu Tien Hoang, Dung D. Le, Kok-Seng Wong

Federated Recommendation (FedRec) systems have emerged as a solution to safeguard users' data in response to growing regulatory concerns.

DiffAugment: Diffusion based Long-Tailed Visual Relationship Recognition

no code implementations1 Jan 2024 Parul Gupta, Tuan Nguyen, Abhinav Dhall, Munawar Hayat, Trung Le, Thanh-Toan Do

The task of Visual Relationship Recognition (VRR) aims to identify relationships between two interacting objects in an image and is particularly challenging due to the widely-spread and highly imbalanced distribution of <subject, relation, object> triplets.

Class-Prototype Conditional Diffusion Model with Gradient Projection for Continual Learning

no code implementations10 Dec 2023 Khanh Doan, Quyen Tran, Tung Lam Tran, Tuan Nguyen, Dinh Phung, Trung Le

To address this, we propose the Gradient Projection Class-Prototype Conditional Diffusion Model (GPPDM), a GR-based approach for continual learning that enhances image quality in generators and thus reduces the CF in classifiers.

From Coupled Oscillators to Graph Neural Networks: Reducing Over-smoothing via a Kuramoto Model-based Approach

no code implementations6 Nov 2023 Tuan Nguyen, Hirotada Honda, Takashi Sano, Vinh Nguyen, Shugo Nakamura, Tan M. Nguyen

We propose the Kuramoto Graph Neural Network (KuramotoGNN), a novel class of continuous-depth graph neural networks (GNNs) that employs the Kuramoto model to mitigate the over-smoothing phenomenon, in which node features in GNNs become indistinguishable as the number of layers increases.

p-Laplacian Transformer

no code implementations6 Nov 2023 Tuan Nguyen, Tam Nguyen, Vinh Nguyen, Tan M. Nguyen

$p$-Laplacian regularization, rooted in graph and image signal processing, introduces a parameter $p$ to control the regularization effect on these data.

Backdoor Attacks and Defenses in Federated Learning: Survey, Challenges and Future Research Directions

no code implementations3 Mar 2023 Thuy Dung Nguyen, Tuan Nguyen, Phi Le Nguyen, Hieu H. Pham, Khoa Doan, Kok-Seng Wong

Federated learning (FL) is a machine learning (ML) approach that allows the use of distributed data without compromising personal privacy.

Federated Learning for ASR based on Wav2vec 2.0

2 code implementations20 Feb 2023 Tuan Nguyen, Salima Mdhaffar, Natalia Tomashenko, Jean-François Bonastre, Yannick Estève

This paper presents a study on the use of federated learning to train an ASR model based on a wav2vec 2. 0 model pre-trained by self supervision.

Sparse*BERT: Sparse Models Generalize To New tasks and Domains

no code implementations25 May 2022 Daniel Campos, Alexandre Marques, Tuan Nguyen, Mark Kurtz, ChengXiang Zhai

Our experimentation shows that models that are pruned during pretraining using general domain masked language models can transfer to novel domains and tasks without extensive hyperparameter exploration or specialized approaches.

On Label Shift in Domain Adaptation via Wasserstein Distance

no code implementations29 Oct 2021 Trung Le, Dat Do, Tuan Nguyen, Huy Nguyen, Hung Bui, Nhat Ho, Dinh Phung

We study the label shift problem between the source and target domains in general domain adaptation (DA) settings.

SP-GPT2: Semantics Improvement in Vietnamese Poetry Generation

1 code implementation10 Oct 2021 Tuan Nguyen, Hanh Pham, Truong Bui, Tan Nguyen, Duc Luong, Phong Nguyen

Both automatic and human evaluation demonstrated that our approach can generate poems that have better cohesion without losing the quality due to additional loss.

STEM: An Approach to Multi-Source Domain Adaptation With Guarantees

1 code implementation1 Oct 2021 Van-Anh Nguyen, Tuan Nguyen, Trung Le, Quan Hung Tran, Dinh Phung

To address the second challenge, we propose to bridge the gap between the target domain and the mixture of source domains in the latent space via a generator or feature extractor.
