Data-induced multiscale losses and efficient multirate gradient descent schemes

no code implementations5 Feb 2024 Juncai He, Liangchen Liu, Yen-Hsi Richard Tsai

This paper investigates the impact of multiscale data on machine learning algorithms, particularly in the context of deep learning.

Efficient and robust Sensor Placement in Complex Environments

no code implementations15 Sep 2023 Lukas Taus, Yen-Hsi Richard Tsai

By taking into account these properties, we discuss the differences in using greedy and $\epsilon$-greedy algorithms to generate data and their impact on the robustness of the network.

Visibility Optimization for Surveillance-Evasion Games

no code implementations18 Oct 2020 Louis Ly, Yen-Hsi Richard Tsai

Although the value function enables optimal controls, it is prohibitively expensive to compute, even for a single pursuer and single evader on a small grid.

Nearest Neighbor Sampling of Point Sets using Rays

no code implementations25 Nov 2019 Liangchen Liu, Louis Ly, Colin Macdonald, Yen-Hsi Richard Tsai

We propose a new framework for the sampling, compression, and analysis of distributions of point sets and other geometric objects embedded in Euclidean spaces.

Greedy Algorithms for Sparse Sensor Placement via Deep Learning

no code implementations17 Sep 2018 Louis Ly, Yen-Hsi Richard Tsai

We consider the exploration problem: an agent equipped with a depth sensor must map out a previously unknown environment using as few sensor measurements as possible.

Automated polyp detection in colon capsule endoscopy

no code implementations8 May 2013 Alexander V. Mamonov, Isabel N. Figueiredo, Pedro N. Figueiredo, Yen-Hsi Richard Tsai

The algorithm acts as a binary classifier, which labels the frame as either containing polyps or not, based on the geometrical analysis and the texture content of the frame.
