Implicit U-KAN2.0: Dynamic, Efficient and Interpretable Medical Image Segmentation

This paper introduces Implicit U-KAN 2.0, a novel medical image segmentation model that combines second-order neural ordinary differential equations (SONO) with MultiKAN layers in a two-phase encoder-decoder architecture to achieve superior performance, enhanced interpretability, and dimension-independent approximation capabilities while reducing computational costs.

Beyond Accuracy: What Matters in Designing Well-Behaved Image Classification Models?

This paper presents a large-scale analysis of 326 image classification models across nine quality dimensions beyond accuracy, revealing that vision-language models, self-supervised initialization, and dataset size significantly influence model behavior, and introduces the QUBA score to holistically rank and recommend models based on specific user needs.

Healthy LLMs? Benchmarking LLM Knowledge of UK Government Public Health Information

This paper introduces PubHealthBench, a new benchmark comprising over 8,000 questions derived from UK government guidance, to evaluate LLMs on public health knowledge and finds that while state-of-the-art models excel in multiple-choice tasks, their performance on free-form responses remains limited, highlighting the need for additional safeguards in real-world applications.

Emotion-Gradient Metacognitive RSI (Part I): Theoretical Foundations and Single-Agent Architecture

This paper establishes the theoretical foundations and single-agent architecture of the Emotion-Gradient Metacognitive RSI (EG-MRSI) framework, a novel system that integrates introspective metacognition and emotion-driven intrinsic motivation to enable provably safe, recursive self-improvement through differentiable reward signals and quantifiable semantic learning metrics.
