Causal Retention in Interactive Agents: Interface Factorization and Selective Adaptation

This work studies causal retention: whether a frozen learned state answers a mechanism-probe map fixed independently of training, including action, context, direct target, value, and delay, which is distinct from task sufficiency and source-domain decodability.

Cost-Aware Best-LLM Identification using Dueling Feedback

A Track-and-Stop style algorithm for best-arm identification with prescribed confidence is proposed, and it is proved that the algorithm almost surely achieves the asymptotically optimal cost as the error tends to zero.

Strategic Self-Consistency

The results suggest that the distribution of additional reasoning paths generated by the algorithm is heavy-tailed and that substantial capacity to overcharge remains even under the best possible audit designed to keep the false-positive rate below $\alpha = 0.1$.

Adaptive multi-resolution Gaussian processes: Scalable exact inference with naturally data-sparse covariance matrices

Theoretical analysis and numerical experiments demonstrate that the model achieves exact inference with $\mathcal{O}(n \log^2 n)$ training cost and $\mathcal{O}(\log^d n)$ prediction cost, establishing a principled framework for scalable and high-fidelity Gaussian process regression.

DIAL: Position-Debiased LLM Judges with Adaptive Human Preference Calibration

DIAL is introduced, a unified framework that combines abundant LLM comparisons with limited human comparisons to separate judge-specific position effects, learn shared structure in position-debiased LLM preferences, and adaptively calibrate that structure toward the human preference target.

Atelier: Learning Local Self-Supervised Features for CryoEM Volumes via Hypernetworks

Atelier is a self-supervised framework that amortizes INR fitting for reconstructed cryoEM maps, a transformer-based hypernetwork that generates high-fidelity reconstructions across a wide range of protein structures, including large multi-subunit assemblies.

Phytochemical Characterisation and Antiinflammatory Evaluation of a Dual Extract In-situ Gel from Sesamum indicum and Rubus idaeus: An In-vitro Study

The raspberry-sesame dual herbal in-situ gel demonstrated favourable physicochemical properties and appreciable in-vitro anti-inflammatory activity, suggesting its potential as a safe topical herbal alternative.

Finding Icebergs in Language-Model Workflow: Diagnosing Latent Structural Fragility with Stochastic Semantic Evidence Graphs

AI-workflow governance cannot be reduced to checking the final answer: an apparently safe answer may rest on a fragile evidence path that ordinary evaluation cannot see, localize or govern, so SSEG moves governance below surface-level output checking into auditable, path-specific decisions about intervention, revalidat...

MultiwayPAM: Multiway Partitioning Around Medoids for LLM-as-a-Judge Score Analysis

LLM-as-a-Judge is a flexible framework for text evaluation, which allows us to obtain scores for the quality of a given text from various perspectives by changing the prompt template. Two main challenges in using LLM-as-a-Judge are computational cost of inference using a large language model (LLM), especially when eval...

Stacked SVD or SVD stacked? A Random Matrix Theory perspective on data integration

Modern data analysis increasingly requires identifying shared latent structure across multiple high-dimensional datasets. A commonly used model assumes that the data matrices are noisy observations of low-rank matrices with a shared singular subspace. In this case, two primary methods have emerged for estimating this s...

Time-Varying Bayesian Optimization Without a Metronome

This paper derives the first upper regret bound that explicitly accounts for changes in the observations sampling frequency and formulates practical recommendations about dataset sizes and stale data policies of TVBO algorithms.
