Node Embeddings via Neighbor Embeddings

arXiv:2503.23822v2 Announce Type: replace Abstract: Node embeddings are a paradigm in non-parametric graph representation learning, where graph nodes are embedded into a given vector space to enable downstream processing. State-of-the-art node-embedding algorithms, such as DeepWalk and node2vec, are based on…

EgoCogNav: Cognition-aware Human Egocentric Navigation

arXiv:2511.17581v1 Announce Type: new Abstract: Modeling the cognitive and experiential factors of human navigation is central to deepening our understanding of human-environment interaction and to enabling safe social navigation and effective assistive wayfinding. Most existing methods focus on forecasting motions…

NeuroVascU-Net: A Unified Multi-Scale and Cross-Domain Adaptive Feature Fusion U-Net for Precise 3D Segmentation of Brain Vessels in Contrast-Enhanced T1 MRI

arXiv:2511.18422v1 Announce Type: cross Abstract: Precise 3D segmentation of cerebral vasculature from T1-weighted contrast-enhanced (T1CE) MRI is crucial for safe neurosurgical planning. Manual delineation is time-consuming and prone to inter-observer variability, while current automated methods often trade accuracy for computational…

Multi-Value Alignment for LLMs via Value Decorrelation and Extrapolation

arXiv:2511.17579v1 Announce Type: new Abstract: With the rapid advancement of large language models (LLMs), aligning them with human values for safety and ethics has become a critical challenge. This problem is especially challenging when multiple, potentially conflicting human values must…

Binary BPE: A Family of Cross-Platform Tokenizers for Binary Analysis

arXiv:2511.17573v1 Announce Type: new Abstract: Sequence models for binary analysis are bottlenecked by byte-level tokenization: raw bytes waste precious context window capacity for transformers and other neural network architectures, and many existing text-oriented tokenizers fail on arbitrary 0x00–0xFF sequences. To…
