VerNav: Verifier-First Low-Latency Vision-and-Language Navigation

Vision-and-Language Navigation (VLN) requires an agent to navigate through unseen 3D environments according to natural-language instructions. Explicit reasoning can improve instruction understanding and semantic grounding, but autoregressive generation at every step accumulates large decision-stage latency over multi-s...

Mode Connectivity Beyond Classifiers: Evidence from Generative and Contrastive Models

This work demonstrates for the first time that mode connectivity between independently trained DDPM and NanoCLIP modes is discovered, and provides a novel perspective for understanding the geometric properties of the loss landscapes in modern generative and contrastive models.
