Transfer Learning in ECG Diagnosis: Is It Effective?

1 code implementation3 Feb 2024 Cuong V. Nguyen, Cuong D. Do

The adoption of deep learning in ECG diagnosis is often hindered by the scarcity of large, well-labeled datasets in real-world scenarios, leading to the use of transfer learning to leverage features learned from larger datasets.

Explainable Severity ranking via pairwise n-hidden comparison: a case study of glaucoma

no code implementations5 Dec 2023 Hong Nguyen, Cuong V. Nguyen, Shrikanth Narayanan, Benjamin Y. Xu, Michael Pazzani

Primary open-angle glaucoma (POAG) is a chronic and progressive optic nerve condition that results in an acquired loss of optic nerve fibers and potential blindness.

Simple Transferability Estimation for Regression Tasks

1 code implementation1 Dec 2023 Cuong N. Nguyen, Phong Tran, Lam Si Tung Ho, Vu Dinh, Anh T. Tran, Tal Hassner, Cuong V. Nguyen

We consider transferability estimation, the problem of estimating how well deep learning models transfer from a source to a target task.

MELEP: A Novel Predictive Measure of Transferability in Multi-Label ECG Analysis

no code implementations27 Oct 2023 Cuong V. Nguyen, Hieu Minh Duong, Cuong D. Do

We introduce MELEP, which stands for Muti-label Expected Log of Empirical Predictions, a novel measure to estimate how effective it is to transfer knowledge from a pre-trained model to a downstream task in a multi-label settings.

Streaming Sparse Gaussian Process Approximations

3 code implementations NeurIPS 2017 Thang D. Bui, Cuong V. Nguyen, Richard E. Turner

Sparse pseudo-point approximations for Gaussian process (GP) models provide a suite of methods that support deployment of GPs in the large data regime and enable analytic intractabilities to be sidestepped.
