Real Eyes Realize Faster: Gaze Stability and Pupil Novelty for Efficient Egocentric Learning

This paper introduces a training-free, capture-time frame curation method for always-on egocentric cameras that leverages gaze stability and pupil-derived novelty as complementary criteria to efficiently select high-quality, informative frames, achieving full-stream classification performance with only 10% of the data while respecting wearable device constraints.

Understanding Sources of Demographic Predictability in Brain MRI via Disentangling Anatomy and Contrast

This paper proposes a disentangled representation learning framework for brain MRI to demonstrate that demographic predictability primarily stems from anatomical variation rather than acquisition-dependent contrast, highlighting the need for targeted mitigation strategies that address these distinct sources to ensure robust bias reduction.

Mask-Guided Attention Regulation for Anatomically Consistent Counterfactual CXR Synthesis

This paper proposes an inference-time attention regulation framework that utilizes anatomy-aware gating and pathology-guided latent corrections to achieve anatomically consistent and precisely localized counterfactual chest X-ray synthesis, effectively overcoming the structural drift and unstable pathology expression issues common in standard diffusion-based editing methods.

HBRB-BoW: A Retrained Bag-of-Words Vocabulary for ORB-SLAM via Hierarchical BRB-KMeans

This paper proposes HBRB-BoW, a refined hierarchical training algorithm that integrates global real-valued flows to preserve high-fidelity descriptor information before final binarization, thereby overcoming the precision loss of traditional binary clustering and significantly enhancing the discriminative power and performance of ORB-SLAM in loop closing and relocalization tasks.

LISTA-Transformer Model Based on Sparse Coding and Attention Mechanism and Its Application in Fault Diagnosis

This paper proposes a LISTA-Transformer model that integrates Learnable Iterative Shrinkage Threshold Algorithm-based sparse coding with the Transformer architecture to overcome the limitations of CNNs and standard Transformers in local and global feature modeling, achieving a 98.5% fault recognition rate on the CWRU dataset through time-frequency signal analysis.

Beyond Mixtures and Products for Ensemble Aggregation: A Likelihood Perspective on Generalized Means

This paper establishes a principled theoretical framework for density aggregation by demonstrating that normalized generalized means with order r[0,1]r \in [0,1] are the only rules guaranteeing systematic improvements in log-likelihood over individual distributions, thereby providing a unified justification for the widespread use of linear and geometric pooling in Deep Ensembles.
