FlashAttention with Statistics: Low-Overhead Attention Features for Compact Hallucination Detectors

Andrei Volodichev, Maksim Savichev, Nikita Sviridov +3

Large language models can produce fluent answers that the supplied context does not support. A compact frozen proxy model can detect such answers by reading the context and another…

Recursive Offline Distillation via Entropy Gain Sampling and Answer Mixing

Andrey Goncharov, Daniil Vyazhev, Simon Epanov +1

Distillation of reasoning chains from Large Language Models (LLMs) into their smaller siblings is a standard training approach. Frequently, researchers do not have full access to a…

Reliable Risk Estimation with Kernel Mean Matching under Dependent Sampling

Alexey Zaytsev, Diana Koldasbayeva, Egor Serov

Kernel Mean Matching (KMM) estimates risk under covariate shift by reweighting labelled source samples so that their kernel mean embedding matches that of unlabeled target samples.…

MercerFlow: Flow Matching in a Kernel-Induced Latent Space for Probabilistic Forecasting

Ilya Kuleshov, Egor Serov, Alexey Zaytsev

Recent work has shown that probabilistic flow matching for time series forecasting benefits from a data-matched prior. The resulting prior introduces local correlations, which a se…

Mixed-Prior Decision Risk for Open-Set Recognition

L. A. Erlygin, P. D. Proskura, A. A. Zaytsev

In open-set recognition (OSR), a probe must either be identified as one of the known gallery classes or rejected as unknown, so three error types coexist: false acceptance, false r…

InDiD: Instant Disorder Detection via Representation Learning

Evgenia Romanenkova, Alexander Stepikin, Matvey Morozov +1

For sequential data, a change point is a moment of abrupt regime switch in data streams. Such changes appear in different scenarios, including simpler data from sensors and more ch…
