K-frames: Scene-Driven Any-k Keyframe Selection for long video understanding

arXiv:2510.13891v1 Announce Type: new Abstract: Multimodal Large Language Models (MLLMs) have demonstrated significant capabilities in image understanding, but long-video are constrained by context windows and computational cost. Uniform frame sampling often leads to substantial information loss. Meanwhile existing keyframe selection…

Joint Discriminative-Generative Modeling via Dual Adversarial Training

arXiv:2510.13872v1 Announce Type: new Abstract: Simultaneously achieving robust classification and high-fidelity generative modeling within a single framework presents a significant challenge. Hybrid approaches, such as Joint Energy-Based Models (JEM), interpret classifiers as EBMs but are often limited by the instability…

Deep Edge Filter: Return of the Human-Crafted Layer in Deep Learning

arXiv:2510.13865v1 Announce Type: new Abstract: We introduce the Deep Edge Filter, a novel approach that applies high-pass filtering to deep neural network features to improve model generalizability. Our method is motivated by our hypothesis that neural networks encode task-relevant semantic…

Thompson Sampling via Fine-Tuning of LLMs

arXiv:2510.13328v2 Announce Type: replace Abstract: Bayesian optimization in large unstructured discrete spaces is often hindered by the computational cost of maximizing acquisition functions due to the absence of gradients. We propose a scalable alternative based on Thompson sampling that eliminates…

LTR-ICD: A Learning-to-Rank Approach for Automatic ICD Coding

arXiv:2510.13922v1 Announce Type: new Abstract: Clinical notes contain unstructured text provided by clinicians during patient encounters. These notes are usually accompanied by a sequence of diagnostic codes following the International Classification of Diseases (ICD). Correctly assigning and ordering ICD codes…

Uncertainty Quantification with the Empirical Neural Tangent Kernel

arXiv:2502.02870v2 Announce Type: replace-cross Abstract: While neural networks have demonstrated impressive performance across various tasks, accurately quantifying uncertainty in their predictions is essential to ensure their trustworthiness and enable widespread adoption in critical systems. Several Bayesian uncertainty quantification (UQ) methods…

Distributional Consistency Loss: Beyond Pointwise Data Terms in Inverse Problems

arXiv:2510.13972v1 Announce Type: new Abstract: Recovering true signals from noisy measurements is a central challenge in inverse problems spanning medical imaging, geophysics, and signal processing. Current solutions balance prior assumptions regarding the true signal (regularization) with agreement to noisy measured…

Efficient & Correct Predictive Equivalence for Decision Trees

arXiv:2509.17774v4 Announce Type: replace-cross Abstract: The Rashomon set of decision trees (DTs) finds importance uses. Recent work showed that DTs computing the same classification function, i.e. predictive equivalent DTs, can represent a significant fraction of the Rashomon set. Such redundancy…
