Sleep Staging from Airflow Signals Using Fourier Approximations of Persistence Curves
Shashank Manjunath, Hau-Tieng Wu, Aarti Sathyanarayana
Sleep staging is a challenging task, typically manually performed by sleep technologists based on electroencephalogram and other biosignals of patients taken during overnight sleep…
Landmark Alternating Diffusion
Sing-Yuan Yeh, Hau-Tieng Wu, Ronen Talmon +1
Alternating Diffusion (AD) is a commonly applied diffusion-based sensor fusion algorithm. While it has been successfully applied to various problems, its computational burden remai…
Convergence analysis of t-SNE as a gradient flow for point cloud on a manifold
Seonghyeon Jeong, Hau-Tieng Wu
We present a theoretical foundation regarding the boundedness of the t-SNE algorithm. t-SNE employs gradient descent iteration with Kullback-Leibler (KL) divergence as the objectiv…
Design a Metric Robust to Complicated High Dimensional Noise for Efficient Manifold Denoising
Hau-Tieng Wu
In this manuscript, we propose an efficient manifold denoiser based on landmark diffusion and optimal shrinkage under the complicated high dimensional noise and compact manifold se…
