Coding Schemes and Converse Bounds for Secure, Multi-Access, and Multi-Antenna Coded Caching Problems
With rapid advancements in technology, there is an increase in the adoption of data-hungry applications, especially entertainment services like on-demand music and video streaming and download. The high temporal variability ...
Design of Placement Delivery Arrays for Shared Cache and Multi-antenna Coded Caching Problems
Caching has been considered as a promising technique to handle the exponential growth of wireless data traffic. The caches distributed across the network are utilized to shift some of the peak-hour traffic to off-peak ...
Group Testing: A Probably Approximately Correct Analysis and Recovery Algorithms for pooled RT-qPCR
The goal of group testing, also called pool testing, is to successfully identify a set of k defectives from a population of n items using only m (< n) group tests. In each group test, a subset of the n items is tested ...
Label Efficient and Generalizable No-reference Video Quality Assessment
No-reference (NR) video quality assessment (VQA) refers to the study of the quality of
degraded videos without the need for reference pristine videos. The problem has wide
applications ranging from the quality assessment ...
Integrated Nanophotonic Devices Based on Van der Waals materials for Applications in Nonlinear and Quantum Photonics
Integrated photonics is a promising technology for realizing miniaturized optical systems with enhanced stability and performance for applications in light-based communication, sensing, imaging, biomedical diagnostics etc. ...
Sequential Transfer in Multi-Armed Bandits using Reward Samples
We consider a sequential multi-task problem, where each task is modeled as a stochastic multi-armed bandit with K arms. We study the problem of transfer learning in this setting and propose algorithms based on UCB to ...
Towards Practical High Throughput Laser-based Indoor Optical Wireless Communication Systems
Wireless communication has become an essential necessity in our day-to-day life with majority of these systems currently use radio frequency (RF) technology to transmit information. To meet the high end requirements, new ...
Electronic Devices using Low-Dimensional van der Waals Materials and Their Heterojunctions
As the state of the art in computation, communication and sensing advances, there is an ever-increasing search for novel materials and device architectures to satisfy the growing demands for more functionality, performance, ...
RSMA Architectures for Downlink Communication Systems
Demand for the internet is increasing day by day, and the number of internet users is also growing drastically. Multiple access (MA) plays an important role in the fifth-generation (5G) and upcoming sixth-generation (6G) ...
Learning with Multi-domain and Multi-view Graph Data
In many applications, we observe large volumes of data supported on irregular (non-Euclidean) domains. In graph signal processing (GSP) and graph machine learning (GML), data is indexed using the nodes of a graph and ...
