Spatio-Temporal Event Graph Navigation is proposed, a training-free framework that extends conventional scene graphs into spatio-temporal event graphs along complementary spatial and temporal axes and demonstrates that event-driven spatio-temporal representations improve navigation reliability and cross-subtask experie...

LookStep is proposed, a unified end-to-end framework that combines Language Centric Future State Modeling and Event Driven Rolling Memory that uses language labels to generate coarse-grained navigation progress and future states for each candidate action, while autonomously deciding whether to write each observation in...

Vision-Language Navigation (VLN) requires an embodied agent to follow natural-language instructions in unseen environments. Recent progress has been largely driven by Multimodal Large Language Models (MLLMs). Existing methods follow a next-step action prediction paradigm, supervising only the expert action, which requi...

Experiments show that NeSy-Spatial consistently improves reasoning accuracy with more precise tool utilization, and is proposed as a neuro-symbolic framework for self-evolving spatial skills.
