3D Object Representations for Robot Perception
(2019)Reasoning about 3D objects is one of the most critical perception problems robots face; outside of navigation, most interactions between a robot and its environment are object-centric. Object-centric robot perception has ... -
A Data-Intensive Framework for Analyzing Dynamic Supreme Court Behavior
(2012)Many law professors and scholars think of the Supreme Court as a black box--issues and arguments go in to the Court, and decisions come out. The almost mystical nature that these researchers impute to the Court seems to ... -
A Logical Controller Architecture for Network Security
(2020)Networked infrastructure-as-a-service testbeds are evolving with higher capacity and more advanced capabilities. Modern testbeds offer stitched virtual circuit capability, programmable dataplanes with software-defined networking ... -
A New Take on Gamification: Playing the Culture Shock Experience in a Digital Card Game
(2020)In 2018-2019, over 1 million international students from all over the world come to the United States to seek higher education. Along with their hope for quality education, they bring their own cultures. The clash of the ... -
A NEW ZEROTH-ORDER ORACLE FOR DISTRIBUTED AND NON-STATIONARY LEARNING
(2021)Zeroth-Order (ZO) methods have been applied to solve black-box or simulation-based optimization prroblems. These problems arise in many important applications nowa- days, e.g., generating adversarial attacks on machine learning ... -
A Privacy Preserving Algorithm to Release Sparse High-dimensional Histograms
(2017)Differential privacy (DP) aims to design methods and algorithms that satisfy rigorous notions of privacy while simultaneously providing utility with valid statistical inference. More recently, an emphasis has been placed ... -
A Q-Learning Approach to Minefield Characterization from Unmanned Aerial Vehicles
(2012)The treasure hunt problem to determine how a computational agent can maximize its ability to detect and/or classify multiple targets located in a region of interest (ROI) populated with multiple obstacles. One particular ... -
A Semi-Supervised Predictive Model to Link Regulatory Regions to Their Target Genes
(2015)Next generation sequencing technologies have provided us with a wealth of data profiling a diverse range of biological processes. In an effort to better understand the process of gene regulation, two predictive machine learning ... -
