R^2-HGP: A Double-Regularized Gaussian Process for Heterogeneous Transfer Learning

arXiv:2512.10258v1 Announce Type: new Abstract: Multi-output Gaussian process (MGP) models have attracted significant attention for their flexibility and uncertainty-quantification capabilities, and have been widely adopted in multi-source transfer learning scenarios due to their ability to capture inter-task correlations. However, they…

Trustworthy scientific inference with generative models

arXiv:2508.02602v2 Announce Type: replace-cross Abstract: Generative artificial intelligence (AI) excels at producing complex data structures (text, images, videos) by learning patterns from training examples. Across scientific disciplines, researchers are now applying generative models to “inverse problems” to directly predict hidden…

Luxical: High-Speed Lexical-Dense Text Embeddings

arXiv:2512.09015v2 Announce Type: replace-cross Abstract: Frontier language model quality increasingly hinges on our ability to organize web-scale text corpora for training. Today’s dominant tools trade off speed and flexibility: lexical classifiers (e.g., FastText) are fast but limited to producing classification…

Bidirectional Representations Augmented Autoregressive Biological Sequence Generation

arXiv:2510.08169v3 Announce Type: replace Abstract: Autoregressive (AR) models, common in sequence generation, are limited in many biological tasks such as de novo peptide sequencing and protein modeling by their unidirectional nature, failing to capture crucial global bidirectional token dependencies. Non-Autoregressive…
