How QuatRoPE Breaks 3D Spatial Reasoning Bottlenecks for Large Language Models

The paper introduces QuatRoPE, a quaternion‑based 3D position embedding that, together with the IGRE isolation mechanism and the ASR benchmark, dramatically improves large language models' ability to encode and reason about object relationships in 3D scenes, as demonstrated by extensive experiments on multiple 3D VL datasets.

How JanusVLN Redefines Vision‑Language Navigation with Dual Implicit Memory

JanusVLN presents a groundbreaking Vision‑and‑Language Navigation framework that decouples semantic understanding from spatial geometry using dual implicit memory, eliminates explicit memory overhead, achieves state‑of‑the‑art performance with only RGB video input, and dramatically improves efficiency and generalization across VLN benchmarks.
