Sound Logical Explanations for Mean Aggregation Graph Neural Networks

arXiv:2511.11593v1 Announce Type: new Abstract: Graph neural networks (GNNs) are frequently used for knowledge graph completion. Their black-box nature has motivated work that uses sound logical rules to explain predictions and characterise their expressivity. However, despite the prevalence of GNNs…

STEP: Success-Rate-Aware Trajectory-Efficient Policy Optimization

arXiv:2511.13091v1 Announce Type: cross Abstract: Multi-turn interaction remains challenging for online reinforcement learning. A common solution is trajectory-level optimization, which treats each trajectory as a single training sample. However, this approach can be inefficient and yield misleading learning signals: it…

Scaling Spatial Intelligence with Multimodal Foundation Models

arXiv:2511.13719v1 Announce Type: cross Abstract: Despite remarkable progress, multimodal foundation models still exhibit surprising deficiencies in spatial intelligence. In this work, we explore scaling up multimodal foundation models to cultivate spatial intelligence within the SenseNova-SI family, built upon established multimodal…

Clustering-Based Weight Orthogonalization for Stabilizing Deep Reinforcement Learning

arXiv:2511.11607v1 Announce Type: new Abstract: Reinforcement learning (RL) has made significant advancements, achieving superhuman performance in various tasks. However, RL agents often operate under the assumption of environmental stationarity, which poses a great challenge to learning efficiency since many environments…
