This paper introduces "Whisperer," a sample-efficient visual prompting framework that bootstraps frozen OCR models by using a four-stage behavioral cloning curriculum to learn diffusion-based preprocessors that enhance degraded text inputs, achieving an 8% absolute reduction in Character Error Rate without modifying the downstream model's weights.
This paper demonstrates that distribution shift is the primary cause of performance degradation in deeper layers of Vision Transformers and reveals that optimal out-of-distribution probing requires selecting between feedforward network activations and normalized self-attention outputs depending on the severity of the shift.
This paper proposes Bayesian Supervised Causal Clustering (BSCC), a novel framework that identifies homogeneous patient subgroups by simultaneously clustering individuals based on their covariate profiles and treatment effects, and validates its practical utility through simulations and real-world data from the International Stroke Trial.
This paper establishes a formal geometric framework linking AI debate and RLAIF by demonstrating that the value of debate scales with knowledge divergence between models, transitioning from negligible benefit to essential oversight as representations diverge, while identifying specific regimes where debate unlocks inaccessible outcomes or risks coordination failure.
The paper proposes Latent Policy Steering (LPS), a robust offline reinforcement learning method that achieves state-of-the-art performance by using a differentiable one-step MeanFlow policy to backpropagate original-action-space Q-gradients directly to a latent actor, thereby eliminating the need for proxy latent critics and sensitive hyperparameter tuning while ensuring policies remain within dataset support.
WavSLM is a single-stream speech language model that achieves competitive speech generation and consistency without text supervision by quantizing and distilling WavLM representations into a single codebook for autoregressive next-chunk prediction.
This paper proposes using asymmetric Shapley values as a superior metric for quantifying the importance of high-dimensional genomic features in clinical prediction models, addressing limitations of traditional approaches by accounting for collinearity and known causal directions, and provides efficient algorithms validated through a colorectal cancer progression study.
This paper introduces GALACTIC, a unified framework that bridges local and global counterfactual explainability for unsupervised time-series clustering by generating minimal perturbations to cross cluster boundaries and employing a provably efficient submodular optimization algorithm to derive concise, non-redundant global summaries of these transitions.
The paper proposes FairFinGAN, a WGAN-based framework that integrates fairness constraints via a classifier to generate synthetic financial data that effectively mitigates bias against protected attributes while maintaining high utility for downstream predictive tasks.
This paper demonstrates that predictive inference is governed by four distinct, pairwise non-nested admissibility geometries—Blackwell risk dominance, anytime-valid supermartingales, marginal coverage, and Cesàro approachability—each offering a unique certificate of optimality and proving that admissibility is irreducibly relative to the chosen criterion rather than a universal property.
This paper establishes a comprehensive statistical theory for globally optimal empirical risk minimization decision trees by deriving sharp oracle inequalities and minimax optimal rates over a novel piecewise sparse heterogeneous anisotropic Besov space, thereby providing rigorous theoretical guarantees for their performance in high-dimensional regression and classification under both sub-Gaussian and heavy-tailed noise settings.
This paper proposes Geometric-Aware Quantization (GAQ), a framework that enables efficient, low-bit inference for SO(3)-equivariant Graph Neural Networks by decoupling magnitude and direction to rigorously preserve continuous symmetry, thereby achieving significant speedups and memory reductions on molecular simulation benchmarks without compromising physical consistency.
This paper proposes InfoFlow KV, an information-flow-aware method that uses attention-norm signals and global positional reordering to selectively recompute key-value caches, thereby improving the efficiency and accuracy of retrieval-augmented generation for long-context tasks.
This paper introduces TS-BOSS, a scalable, score-based algorithm for learning causal structures in multivariate time series that extends the Best Order Score Search framework with dynamic Bayesian networks and grow-shrink trees, demonstrating superior performance in high auto-correlation regimes compared to standard constraint-based methods.
This paper proposes a novel deep adversarial framework that explicitly integrates inter-subject variability to learn subject-invariant feature representations, thereby significantly improving generalization and classification performance in inertial sensor-based Human Activity Recognition across unseen individuals.
The paper introduces TopKGraphs, a robust and interpretable method for estimating node similarity that combines Jaccard-biased random walks with rank aggregation to outperform standard similarity measures and embedding-based approaches across diverse network types.
This paper challenges the necessity of learnable restriction maps in Sheaf Neural Networks by demonstrating that a simpler baseline with fixed identity maps achieves comparable performance on heterophilic graphs and does not suffer from the oversmoothing predicted by theoretical diffusion analysis.
This paper provides a comprehensive statistical review of synthetic data generated by modern AI models, outlining their benefits and limitations while offering principled frameworks and practical recommendations to ensure their valid and reliable use in scientific inference and prediction.
The paper introduces MobileFetalCLIP, a framework utilizing Selective Repulsive Knowledge Distillation to train a compact 11.4M parameter student model that outperforms its 304M parameter teacher in fetal ultrasound analysis while enabling real-time deployment on mobile devices.
This paper proposes an inherently interpretable, prototype-based neural network for medical tabular data that learns human-readable, discretized feature subsets to provide transparent, case-based clinical predictions while maintaining competitive accuracy.
