InfoDPP-PAC: Principled Patch Selection for Whole Slide Image Analysis
Prateek Mittal, Ayush Srivastava, Joohi Chauhan
Each WSI slide contains thousands of candidate tissue patches, while supervision is usually available only at slide level. Existing bag-construction strategies like Uniform extract…
MURMUR: Using cross-user chatter to break collaborative language agents in groups
Atharv Singh Patlan, Peiyao Sheng, S. Ashwin Hebbar +2
Language agents are rapidly expanding from single-user assistants to multi-user collaborators in shared workspaces and groups. However, today's language models lack a mechanism for…
Context manipulation attacks : Web agents are susceptible to corrupted memory
Atharv Singh Patlan, Ashwin Hebbar, Pramod Viswanath +1
Autonomous web navigation agents, which translate natural language instructions into sequences of browser actions, are increasingly deployed for complex tasks across e-commerce, in…
Real AI Agents with Fake Memories: Fatal Context Manipulation Attacks on Web3 Agents
Atharv Singh Patlan, Peiyao Sheng, S. Ashwin Hebbar +2
AI agents integrated with Web3 offer autonomy and openness but raise security concerns as they interact with financial protocols and immutable smart contracts. This paper investiga…
Adaptive and Stratified Subsampling for High-Dimensional Robust Estimation
Prateek Mittal, Joohi Chauhan
We study robust high-dimensional sparse regression under finite-variance heavy-tailed noise, epsilon-contamination, and alpha-mixing dependence via two subsampling estimators: Adap…
