PRAM-R Framework Overview
PRAM-R integrates Perception, Reasoning, Action, and Memory with LLM-guided modality routing. It operates via an asynchronous dual-loop architecture: a fast reactive loop for immediate control and a slower deliberative loop for refining sensing strategies and memory updates. This design ensures both real-time responsiveness and adaptive behavior under dynamic conditions.
Intelligent LLM-Guided Modality Routing
The core innovation is an LLM-based Qwen3-VL-8B modality router that dynamically selects and weights sensor modalities (camera, LiDAR, radar) based on environmental context and sensor diagnostics. It determines both usage masks (scene complexity) and reliability scores. Hysteresis-based stabilization further reduces routing oscillations by 87.2%, ensuring smooth transitions and robust performance in varying conditions.
Hierarchical Memory Architecture for Long-Term Adaptation
PRAM-R employs a four-layer hierarchical memory:
- P-Memory (short-term: routing context, semantic cache)
- R-Memory (mid-term: scene record, seed state)
- A-Memory (mid-term: policy log)
- Knowledge Repository (long-term: distilled experience).
Validated Performance & Stability
Evaluation on synthetic stress tests and nuScenes dataset demonstrates PRAM-R's efficiency and adaptivity. It achieves 6.22% modality reduction and 20% memory recall without degrading trajectory accuracy. Ablation studies confirm the benefits of hierarchical memory and the dual-loop design for improved routing efficiency and stability over static fusion baselines.
