On the Role of Feedback in Test-Time Scaling of Agentic AI Workflows

Souradip Chakraborty, Mohammadreza Pourreza, Ruoxi Sun +8

Agentic AI workflows (systems that autonomously plan and act) are becoming widespread, yet their task success rate on complex tasks remains low. A promising solution is inference-t…

Fundamental Limits of Perfect Concept Erasure

Somnath Basu Roy Chowdhury, Avinava Dubey, Ahmad Beirami +4

Concept erasure is the task of erasing information about a concept (e.g., gender or race) from a representation set while retaining the maximum possible utility -- information from…

CoDe: Blockwise Control for Denoising Diffusion Models

Anuj Singh, Sayak Mukherjee, Ahmad Beirami +1

Aligning diffusion models to downstream tasks often requires finetuning new models or gradient-based guidance at inference time to enable sampling from the reward-tilted posterior.…
