An Improved Greedy Curvature Bound in Finite-Horizon String Optimization with Application to a Sensor Coverage Problem
Brandon Van Over, Bowen Li, Edwin K. P. Chong +1
We study the optimization problem of choosing strings of finite length to maximize string submodular functions on string matroids, which is a broader class of problems than maximiz…
Abstract message passing and distributed graph signal processing
Feng Ji, Yiqi Lu, Wee Peng Tay +1
Graph signal processing is a framework to handle graph structured data. The fundamental concept is graph shift operator, giving rise to the graph Fourier transform. While the graph…
Information-Theoretic Approach to Navigation for Efficient Detection and Classification of Underwater Objects
Christopher Robbiano, Edwin K. P. Chong, Mahmood R. Azimi-Sadjadi
This paper addresses an autonomous exploration problem in which a mobile sensor, placed in a previously unseen search area, utilizes an information-theoretic navigation cost functi…
Automated Pavement Crack Segmentation Using U-Net-based Convolutional Neural Network
Stephen L. H. Lau, Edwin K. P. Chong, Xu Yang +1
Automated pavement crack image segmentation is challenging because of inherent irregular patterns, lighting conditions, and noise in images. Conventional approaches require a subst…
Bayesian Learning of Occupancy Grids
Christopher Robbiano, Edwin K. P. Chong, Mahmood R. Azimi-Sadjadi +2
Occupancy grids encode for hot spots on a map that is represented by a two dimensional grid of disjoint cells. The problem is to recursively update the probability that each cell i…
Decision Automation for Electric Power Network Recovery
Yugandhar Sarkale, Saeed Nozhati, Edwin K. P. Chong +1
Critical infrastructure systems such as electric power networks, water networks, and transportation systems play a major role in the welfare of any community. In the aftermath of d…
