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.

CubeComposer: Spatio-Temporal Autoregressive 4K 360° Video Generation from Perspective Video

CubeComposer is a novel spatio-temporal autoregressive diffusion model that overcomes the computational limitations of existing methods to natively generate high-quality, seam-free 4K-resolution 360° videos from perspective inputs by decomposing them into cubemap representations and employing efficient context management and continuity-aware techniques.
