Unified World Models: Memory-Augmented Planning and Foresight for Visual Navigation

arXiv 25.10 2025 51.2 method, application

TLDR

UniWM integrates visual foresight and planning in a unified memory-augmented world model for visual navigation, achieving up to 30% improvement on benchmarks.

Reasoning

The paper's strength lies in its unified architecture combining memory-augmented world modeling with planning, demonstrated through strong empirical results across multiple benchmarks and zero-shot generalization. Weaknesses include a narrow focus on visual navigation and lack of discussion on failure cases or limitations.

Innovations

Unified world model (UniWM) integrating egocentric visual foresight and planning within a single multimodal autoregressive backbone
Hierarchical memory mechanism fusing short-term perceptual cues with longer-term trajectory context
Explicit grounding of action selection in visually imagined outcomes

Methodology

UniWM is a unified, memory-augmented world model that uses a multimodal autoregressive backbone to integrate visual foresight and planning. It employs a hierarchical memory mechanism to combine short-term perceptual cues with long-term trajectory context for stable reasoning over extended horizons. The model is evaluated on four benchmarks (Go Stanford, ReCon, SCAND, HuRoN) and the 1X Humanoid Dataset, with zero-shot testing on TartanDrive.

Key Results

UniWM improves navigation success rates by up to 30% against strong baselines, substantially reduces trajectory errors, generalizes zero-shot to the unseen TartanDrive dataset, and scales naturally to high-dimensional humanoid control.
