A new constrained multi-source inference framework for distribution system topology identification achieves over 95% reconstruction accuracy across three feeders with more than 8,000 AMI meters, validated with a large U.…
Researchers propose DecodeShare, a protocol that identifies a low-dimensional subspace shared across tasks in LLM decode-time hidden states, and find that disturbing this subspace degrades decision performance more than …
Researchers propose a semi-supervised framework called WSD for distilling text-attributed graphs (TAGs) that integrates graph topology with textual semantics. The method uses dual-pathway encoders and Wasserstein Distanc…
Researchers introduced Lumera, a benchmark and pipeline for engine-native, light-aware 3D scene parsing from a single image, built from 2,513 UE5 projects with 3.73M components and 102.6K parametric lights. Lumera-Box ac…
A study of Microsoft's Aurora weather forecasting foundation model fine-tuned for atmospheric chemistry finds that while it captures a first-order ozone response to reactive nitrogen, it does not enforce the chemical con…
Researchers propose Generative Bayesian Filtering (GBF), a filtering framework that replaces restrictive observation models with pretrained conditional generative models parametrized by conditional variational autoencode…
A new study from arXiv presents the first systematic comparison of methods to inject biokinetic ODE knowledge into neural networks for bioprocess modeling under data scarcity. The researchers found that a generic decoder…

A decision-aware machine learning framework developed by researchers and deployed with the Sierra Leone national government increased consumption of allocated essential medicines by 19% in treated districts, according to…
A new study tests causal emergence in an active inference agent whose architecture separates a fast perception latent z from a slow global latent g, finding that the integrated information measure Φr concentrates in g an…
Researchers propose Cardinality-Decomposed Loss (CDL) to address a silent failure in Graph Neural Networks for heterogeneous recommendation graphs, where Bayesian Personalized Ranking (BPR) causes attribute embeddings to…
Researchers propose Uncertainty-Guided Cascade Forward Refinement (U-CFR), a new inference-time framework for interactive image segmentation that enables models to autonomously self-correct after each user interaction. U…
A new arXiv paper (2607.20533v1) proposes using neural predicates as a structured, probabilistic mechanism for generating investor views in the Black-Litterman portfolio construction model, replacing subjective uncertain…
