Robustness to Modeling Errors in Risk-Sensitive Markov Decision Problems with Markov Risk Measures
Shiping Shao, Abhishek Gupta, William B. Haskell
We consider risk-sensitive Markov decision processes (MDPs), where the MDP model is influenced by a parameter which takes values in a compact metric space. We identify sufficient c…
Requisites on viscoelasticity for exceptional points in passive elastodynamic metamaterials
Abhishek Gupta, Ramathasan Thevamaran
The recent progress of non-Hermitian physics and the notion of exceptional point (EP) degeneracies in elastodynamics has led to the development of novel metamaterials for the contr…
Preemptive Scheduling of EV Charging for Providing Demand Response Services
Shiping Shao, Farshad Harirchi, Devang Dave +1
We develop a new algorithm for scheduling the charging process of a large number of electric vehicles (EVs) over a finite horizon. We assume that EVs arrive at the charging station…
HAA4D: Few-Shot Human Atomic Action Recognition via 3D Spatio-Temporal Skeletal Alignment
Mu-Ruei Tseng, Abhishek Gupta, Chi-Keung Tang +1
Human actions involve complex pose variations and their 2D projections can be highly ambiguous. Thus 3D spatio-temporal or 4D (i.e., 3D+T) human skeletons, which are photometric an…
Effects of Parametric and Non-Parametric Methods on High Dimensional Sparse Matrix Representations
Sayali Tambe, Raunak Joshi, Abhishek Gupta +2
The semantics are derived from textual data that provide representations for Machine Learning algorithms. These representations are interpretable form of high dimensional sparse ma…
Change Detection of Markov Kernels with Unknown Pre and Post Change Kernel
Hao Chen, Jiacheng Tang, Abhishek Gupta
In this paper, we develop a new change detection algorithm for detecting a change in the Markov kernel over a metric space in which the post-change kernel is unknown. Under the ass…
Reconfigurable Enhancement of Actuation Forces by Engineered Losses in non-Hermitian Metamaterials
Abhishek Gupta, Arkady Kurnosov, Tsampikos Kottos +1
While boosting signals with amplification mechanisms is a well established approach, attenuation mechanisms are typically considered an anathema because they degrade the efficiency…
