Zeroth-Order Regularized Optimization (ZORO): Approximately Sparse Gradients and Adaptive Sampling
HanQin Cai, Daniel Mckenzie, Wotao Yin +1
We consider the problem of minimizing a high-dimensional objective function, which may include a regularization term, using (possibly noisy) evaluations of the function. Such optim…
Submodular Optimization Problems and Greedy Strategies: A Survey
Yajing Liu, Edwin K. P. Chong, Ali Pezeshki +1
The greedy strategy is an approximation algorithm to solve optimization problems arising in decision making with multiple actions. How good is the greedy strategy compared to the o…
VRGym: A Virtual Testbed for Physical and Interactive AI
Xu Xie, Hangxin Liu, Zhenliang Zhang +5
We propose VRGym, a virtual reality testbed for realistic human-robot interaction. Different from existing toolkits and virtual reality environments, the VRGym emphasizes on buildi…
A General Framework for Bounding Approximate Dynamic Programming Schemes
Yajing Liu, Edwin Chong, Ali Pezeshki +1
For years, there has been interest in approximation methods for solving dynamic programming problems, because of the inherent complexity in computing optimal solutions characterize…
Inverse Augmented Reality: A Virtual Agent's Perspective
Zhenliang Zhang, Dongdong Weng, Haiyan Jiang +2
We propose a framework called inverse augmented reality (IAR) which describes the scenario that a virtual agent living in the virtual world can observe both virtual objects and rea…
Using mm-Waves for Secret Key Establishment
Mohammed Karmoose, Christina Fragouli, Suhas Diggavi +3
The fact that Millimeter Wave (mmWave) communication needs to be directional is usually perceived as a challenge; in this paper we argue that it enables efficient secret key sharin…
