Evaluation on various datasets shows that standard workarounds fail, and SHAP-RTL maintains correctness compared to other methods. The research emphasizes the need for language-aware visualization to improve explainability across different writing systems.
A leakage-safe protocol using Leave-One-Region-Out cross-validation was proposed for classifying hydrogen-embrittled (H2) and as-received (AR) 316L stainless steel SEM micrographs. The study compared various feature extractors, including local binary patterns, GLCM, self-supervised embeddings, and a CNN, for this task. The simplest LBP+SVM model achieved the best performance, demonstrating the ability to recover hydrogen-charging signatures from texture descriptors. This leakage-safe method statistically validated the recovery of texture information, even with limited samples. The findings suggest that texture descriptors can effectively detect hydrogen embrittlement in materials with few samples.
VINTAGE-TS is a revision-aware adaptation of a time-series foundation model designed to handle evolving historical observations. It distinguishes between the observation time and the time when information becomes available, targeting future values and delayed values. The model predicts a joint distribution that captures the dependence between these targets and exposes uncertainty regarding their difference. The work includes methods for validity-interval reconstruction and a frozen-backbone adapter interface for reproducibility. The methodology is verified through synthetic demonstrations and sensitivity testing, though no empirical foundation-model advantage is claimed from real experiments.
The research analyzes smart-meter data to uncover patterns of residential co-adoption between solar photovoltaic (PV) systems and electric vehicle (EV) charging. A two-part workflow uses dynamic time warping k-means clustering to identify behavioral load archetypes from daily import/export profiles. A bidirectional Long Short-Term Memory (BiLSTM) model is then trained to predict PV/EV activity based on these archetypes. The analysis of half-hourly data from Victoria, Australia, revealed distinct cohorts including PV-only, EV-only, co-adoption, and neither. The model demonstrates strong predictive performance, achieving an AUROC of 0.991 for the detection task.
The paper investigates the concept of auditability in reinforcement learning policies by examining rule overlap, behavioral agreement, and composition. It defines auditability through six testable predicates: trace integrity, lossless coding, rule coverage, behavioral agreement, composition quality, and value-model reliability. The study finds that rule-set overlap does not guarantee behavioral agreement, and fusion failures often stem from mismatches in how rules were induced and deployed. The authors contribute an evidence-bounded protocol for audit and composition rather than a claim of universal interpretability. Future work is suggested to address temporally extended skills and cross-skill interfaces.
The research formalizes task-conditioned active observability complexity, focusing on the minimum interaction cost to identify task-relevant states under certified error guarantees. It addresses limitations of classical observability by considering the necessity of active interventions in unobservable physical systems. The work proves that task-predictive equivalence leads to a minimal sufficient quotient, ensuring active observability complexity remains invariant while removing superfluous distinctions. It establishes complexity characterizations based on optimal distinguishing trees and martingale certificates for both deterministic and noisy regimes. Experimental results show certified state recovery with zero false acceptances and significant reductions in sensor readings.
The research addresses selecting conformal models while adhering to coverage constraints in sequential forecasting. It formulates the problem as sequential inference for a stochastic constrained argmin to find minimum-cost pipelines satisfying conditional miscoverage constraints. The authors introduce Coverage-Constrained Sequential Model Confidence Sets (CC-SMCS) to distinguish between feasible, possibly feasible, and constrained-optimal pipelines. CC-SMCS uses simultaneous martingale confidence sequences to project a confidence region and provides an exact closed-form rule. This framework offers a finite-sample guarantee of containing all constrained-optimal pipelines simultaneously, independent of stationarity assumptions.
A stochastic inertial Krasnosel'skii-Mann (iKM) method is analyzed for finding fixed points of nonexpansive operators in a real Hilbert space. This method is derived by adding inertial extrapolations to stochastic KM, requiring only one biased stochastic oracle call per update. The proposed method achieves a last-iterate fixed-point residual bound of $O\left(\frac{1}{K} +\frac{\sigma\log K}{\sqrt K} +\frac{B_K\log K}{K}\right)$. Under certain conditions, this yields near-optimal sample complexity matching stochastic-oracle lower bounds. Furthermore, the method improves the best-known random-iterate guarantee for stochastic KM and attains the worst-case-optimal rate when the oracle is exact.
The paper characterizes consistent inductive inference by an order-theoretic structure on finite realizable traces. This characterization addresses when a learner can have only finitely many prediction errors along every infinite sequence under an unknown hypothesis. The order must satisfy conditions where conflicting traces select different subtraces and the order is well-founded on the traces of a fixed target. These conditions define a learner whose selected evidence decreases upon every mistake. Conversely, consistent learners yield this order through canonical mistake transcripts and the Kleene--Brouwer ordering.
Evaluating stochastic large language models is costly because benchmark scores estimate expected performance without accounting for rollout variance. Speculative Evaluation introduces a Hierarchical Bayesian Neyman (HBN) policy to minimize variance under an exact rollout budget. The method uses a short uniform pilot to pool success counts with a hierarchical Bayesian model for exact Neyman allocation. HBN-async mitigates pilot synchronization barriers by speculatively executing continuations from partial feedback. This approach reduces variance by 12.8%-33.6% compared to uniform methods, outperforming other baselines.
Aggregation theory has traditionally focused on vector-based operators, neglecting operators on matrices of membership degrees. This paper formalizes the concept of a matrix aggregation operator (MAO) to address this gap in the literature. The research analyzes the decomposability and symmetry properties of MAOs. A family of MAOs called maximum entropy global coverage indices (MEGCIs) is introduced and constructed using grouping functions and MEOWA operators. These indices are demonstrated to be useful for cluster quality assessment through computational studies.
NUMERICJEV is a training-free numerical decoding algorithm designed to extract numerical outputs from Large Language Models based on Jev-like structured-choice interfaces. It achieves this by recursively refining a range using a multiway decision tree while keeping the original context. This method outperforms direct selection from a candidate list by a significant margin on arithmetic benchmarks. The approach demonstrates high accuracy, showing a Range-normalized MAE of 1.84% compared to 5.18% for direct choice. The work also shows zero readout error in a three-date historical-index study when the value is provided.
The study examines Bayesian linear bandits with Gaussian parameters and noise when the horizon scales with the dimension. The normalized posterior uncertainty is shown to have a limit uniform over all causal policies, which determines limiting parameter overlaps. Exact regret curves are derived for Thompson sampling and posterior-mean greedy selection, with the latter attaining the optimal Bayes regret. Thompson sampling exhibits a strictly larger leading regret compared to greedy selection, approaching a ratio of two in the long horizon limit. The instantaneous regret converges to a nondegenerate Gaussian decision-loss distribution.
Deep clustering in latent spaces lacks a statistically reliable method for assessing cluster validity due to selection bias. This work develops a selective inference framework to correct for this bias in deep clustering with a fixed pretrained encoder. The method accounts for the complex selection process arising from the nonlinear transformation to the latent space. Synthetic experiments show the method controls the Type I error rate while offering higher power than conservative baselines. The framework provides a principled way to quantify the statistical reliability of structures discovered via deep clustering.
Federated learning is applied to EEG decoding using two models: Riemannian SPDNet and Euclidean EEGNet. Personalised Federated Learning addresses inter-subject variability by allowing subjects to learn a common trunk while retaining individual heads. Experiments show personalised SPDNet achieves higher accuracy than standard FL and centralized training. Personalized methods also demonstrate convergence in fewer rounds and reduced communication compared to standard FL. Furthermore, personalized SPDNet outperforms Euclidean baselines on some datasets.
