A Diffusion Model to Shrink Proteins While Maintaining Their Function

arXiv:2511.07390v2 Announce Type: replace Abstract: Many proteins useful in modern medicine or bioengineering are challenging to make in the lab, fuse with other proteins in cells, or deliver to tissues in the body, because their sequences are too long. Shortening…

(De)-regularized Maximum Mean Discrepancy Gradient Flow

arXiv:2409.14980v3 Announce Type: replace-cross Abstract: We introduce a (de)-regularization of the Maximum Mean Discrepancy (DrMMD) and its Wasserstein gradient flow. Existing gradient flows that transport samples from source distribution to target distribution with only target samples, either lack tractable numerical…

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…
