The electric power grid is a critical infrastructure system subject to different types of failures which can have devastating impacts on society. One framework to study the resilie…
FloodReasonBench: Benchmarking VLM Reasoning Segmentation for Embodied Flood Response at the Edge
Rajat Bhattacharjya, Yoomee Jung, Minwoo Kim +4
Reasoning segmentation enables vision-language models (VLMs) to translate mission-relevant language requests into pixel-level visual grounding, offering a natural perception interf…
VOILA: Value-of-Information Guided Fidelity Selection for Cost-Aware Multimodal Question Answering
Rahul Atul Bhope, K. R. Jayaram, Vinod Muthusamy +3
Despite significant costs from retrieving and processing high-fidelity visual inputs, most multimodal vision-language systems operate at fixed fidelity levels. We introduce VOILA,…
Meaningful Data Erasure in the Presence of Dependencies
Vishal Chakraborty, Youri Kaminsky, Sharad Mehrotra +5
Data regulations like GDPR require systems to support data erasure but leave the definition of "erasure" open to interpretation. This ambiguity makes compliance challenging, especi…
DIM-SUM: Dynamic IMputation for Smart Utility Management
Ryan Hildebrant, Rahul Bhope, Sharad Mehrotra +2
Time series imputation models have traditionally been developed using complete datasets with artificial masking patterns to simulate missing values. However, in real-world infrastr…
Shift Happens: Mixture of Experts based Continual Adaptation in Federated Learning
Rahul Atul Bhope, K. R. Jayaram, Praveen Venkateswaran +1
Federated Learning (FL) enables collaborative model training across decentralized clients without sharing raw data, yet faces significant challenges in real-world settings where cl…
FLIPS: Federated Learning using Intelligent Participant Selection
Rahul Atul Bhope, K. R. Jayaram, Nalini Venkatasubramanian +2
This paper presents the design and implementation of FLIPS, a middleware system to manage data and participant heterogeneity in federated learning (FL) training workloads. In parti…
FedGen: Generalizable Federated Learning for Sequential Data
Praveen Venkateswaran, Vatche Isahagian, Vinod Muthusamy +1
Existing federated learning models that follow the standard risk minimization paradigm of machine learning often fail to generalize in the presence of spurious correlations in the…
IoT Notary: Attestable Sensor Data Capture in IoT Environments
Nisha Panwar, Shantanu Sharma, Guoxi Wang +4
Contemporary IoT environments, such as smart buildings, require end-users to trust data-capturing rules published by the systems. There are several reasons why such a trust is misp…
Concealer: SGX-based Secure, Volume Hiding, and Verifiable Processing of Spatial Time-Series Datasets
Peeyush Gupta, Sharad Mehrotra, Shantanu Sharma +2
This paper proposes a system, entitled Concealer that allows sharing time-varying spatial data (e.g., as produced by sensors) in encrypted form to an untrusted third-party service…
Quest: Practical and Oblivious Mitigation Strategies for COVID-19 using WiFi Datasets
Peeyush Gupta, Sharad Mehrotra, Nisha Panwar +3
Contact tracing has emerged as one of the main mitigation strategies to prevent the spread of pandemics such as COVID-19. Recently, several efforts have been initiated to track ind…
Canopy: A Verifiable Privacy-Preserving Token Ring based Communication Protocol for Smart Homes
Nisha Panwar, Shantanu Sharma, Guoxi Wang +2
This paper focuses on the new privacy challenges that arise in smart homes. Specifically, the paper focuses on inferring the user's activities -- which may, in turn, lead to the us…
LOCATER: Cleaning WiFi Connectivity Datasets for Semantic Localization
Yiming Lin, Daokun Jiang, Roberto Yus +4
This paper explores the data cleaning challenges that arise in using WiFi connectivity data to locate users to semantic indoor locations such as buildings, regions, rooms. WiFi con…
