Fooling Algorithms in Non-Stationary Bandits using Belief Inertia

The proof combines two deterministic obstructions: a stationary small-gap instance that makes repeated forgetting costly, and a one-breakpoint instance that creates a strict post-change index lock that yields an algorithmic separation.

Quantum Geometry of Data

The present work provides the first full exposition of QCML as a framework for quantum geometry, establishing its mathematical foundation and demonstrating how operator-level tools from quantum geometry can be directly applied to data.

ReCIRC: Rectified Conformal Risk Control

Many applications of black-box predictive models require controlling task-relevant error rates, such as missed lesion pixels in segmentation or missed labels in multilabel classification. Conformal risk control (CRC; Angelopoulos et al., arXiv:2208.02814) gives distribution-free guarantees for such losses, but it calib...

Latent Inference-Time Guidance of Time Series Foundation Models

Latent Inference-Time Guidance for TSFMs is introduced, which adaptively combines a pool of TSFM forecasts through a time-dependent latent space with independent components that comes equipped with identifiability and reconstruction guarantees, whilst maintaining the off-the-shelf aspect of foundation models.

Mutual Information Constrained Chernoff Bottleneck

The classical information bottleneck (IB) measures the relevance of a representation $U$ of $X$ to a target $Y$ by $I(U;Y)$, which does not directly characterize the error of downstream decisions. For a binary hypothesis $Y$ inferred from many separately encoded observations, the optimal error exponent is the Chernoff...

Identifiability Guarantees for Drivers and Dynamics of Delayed Physical Systems

A wide range of methods have been proposed, including physics-informed neural networks, which are powerful but do not guarantee identifiability of the dynamics, symbolic regression, which requires a set of precomputed operations, and causal discovery, which is more principled but usually relies on strong assumptions th...

Post-Anomaly Detection Inference for Deep SVDD

PADI (Post-Anomaly Detection Inference), a novel framework that equips a trained and frozen Deep SVDD detector with statistically valid inference by leveraging the Selective Inference framework, is proposed, providing a principled approach for statistically reliable inference in semi-supervised anomaly detection settin...

A Finslerian Approach for Embedding Directed Data

Many datasets carry an intrinsic directionality: citations point backward in time, cells differentiate along lineages, and traffic follows preferred routes. Spectral embedding methods, including most of their extensions to directed graphs, discard this information: they symmetrize the data and map it into a Euclidean s...

Ornstein-Uhlenbeck Is Hard to Beat, Yet Superlinear Drift Ships Lower Transport Costs

Bre\v{s}ar and Mijatovi\'c \cite{bresar2025} show that Ornstein--Uhlenbeck diffusion is hard to beat in forward convergence under assumptions that exclude superlinear drift. We instead test superlinear Langevin diffusions for score-based image generation, computing their conditional scores numerically from a Fokker--Pl...

Into the danger zone: stable extrapolation in high-dimensional function and operator learning

Out-of-distribution (OOD) generalization is a central challenge in scientific machine learning. We study regression problems in which the test distribution differs from the training distribution and ask: under what assumptions on the target function or operator is stable extrapolation possible, and how far beyond the t...

Hierarchical Utility Calibration for Structured Multiclass Decisions

In multiclass probabilistic prediction, Utility Calibration (UC), which focuses auditing on specified utilities, has recently received attention as a way to guarantee downstream decisions while controlling computational and sample requirements. At the same time, some multiclass problems have meaningful label hierarchie...
