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…
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…
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…
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…
