Agreement versus Softmax under Spatial Disambiguation
Michał Zakrzewski, Mariia Shpir, Taras Rumezhak +1
ScanRefer Multiple queries require spatial disambiguation: several instances of the target class are present, and the referencer must pick one. When per-query logits were never log…
Running the Gauntlet: Hard Agentic Tasks
Mykola Vysotskyi, Runqi Lin, Grzegorz Biziel +21
As agentic systems continue to evolve and are widely deployed in real-world scenarios, there is a growing demand to faithfully evaluate their capabilities. However, current benchma…
Critic-Guided Reinforcement Unlearning in Text-to-Image Diffusion
Mykola Vysotskyi, Zahar Kohut, Mariia Shpir +2
Machine unlearning in text-to-image diffusion models aims to remove targeted concepts while preserving overall utility. Prior diffusion unlearning methods typically rely on supervi…
Just on Time: Token-Level Early Stopping for Diffusion Language Models
Zakhar Kohut, Severyn Shykula, Mykola Vysotskyi +7
Diffusion language models generate text through iterative refinement, a process that is often computationally inefficient because many tokens reach stability long before the final…
