Adapting AlphaEvolve to Optimize Fully Homomorphic Encryption on TPUs

Shruthi Gorantala, Jianming Tong, Asra Ali +7

The deployment of Fully Homomorphic Encryption (FHE) at scale is hindered due to its heavy computational overhead. While specialized hardware accelerators like Google Tensor Proces…

Reinforced Generation of Combinatorial Structures: Hardness of Approximation

Ansh Nagda, Prabhakar Raghavan, Abhradeep Thakurta

Can AI based methods help us make advances in complexity theory? We provide evidence towards answering this in the affirmative, using AlphaEvolve (an LLM code mutation agent) to ob…

Preserving Expert-Level Privacy in Offline Reinforcement Learning

Navodita Sharma, Vishnu Vinod, Abhradeep Thakurta +4

The offline reinforcement learning (RL) problem aims to learn an optimal policy from historical data collected by one or more behavioural policies (experts) by interacting with an…

The Attacker Moves Second: Stronger Adaptive Attacks Bypass Defenses Against Llm Jailbreaks and Prompt Injections

Milad Nasr, Nicholas Carlini, Chawin Sitawarin +11

How should we evaluate the robustness of language model defenses? Current defenses against jailbreaks and prompt injections (which aim to prevent an attacker from eliciting harmful…
