Towards Robust Speech Deepfake Detection via Human-Inspired Reasoning

Artem Dvirniak, Evgeny Kushnir, Dmitrii Tarasov +5

The paper introduces HIR‑SDD, a speech deepfake detection framework that leverages large audio language models and chain‑of‑thought reasoning from a human‑annotated dataset to impr…

A Polynomial Recovery Criterion for Forced Commutativity in the Matrix Square-Root Fiber of a Square-Free Cubic Polynomial

Oleg Kiriukhin

Let be an algebraically closed field of characteristic different from and , and let be square-free. For set . This paper st…

Orbit-Level Transfer Matrix for the 3D Fourier-Galerkin Navier-Stokes System on the Periodic Torus: Explicit Orbit-Triad Incidence Bounds and Deterministic Row-Sum Estimates

Oleg Kiriukhin

I study the cubic Fourier-Galerkin truncation of the three-dimensional (3D) incompressible Navier-Stokes equations on the periodic torus after reduction by the full octahedral symm…

A Strict Gap Between Relaxed and Partition-Constrained Spectral Compression in a Six-State Lumpable Markov Chain

Oleg Kiriukhin

This paper studies a finite reversible lumpable Markov chain for which relaxed spectral compression yields a larger determinant than partition-constrained compression. For a symmet…

Variable-Length Markov Chains on Finite Quivers: Boundary-Window Identifiability, Exact Depth, and Local Rank Comparison

Oleg Kiriukhin

Variable-length Markov chains on finite quivers provide a natural framework for context-dependent stochastic growth under incidence constraints. I study quiver-valued variable-leng…

Entropy-Rate Selection for Partially Observed Processes

Oleg Kiriukhin

I formulate an entropy-rate maximization problem at the observable level for stochastic processes observed through an information-reducing observation map. For a visible stationary…
