Connectivity-Regime Framework for Offline RAG on Raspberry Pi 5
October 23, 2026
A new framework classifies inference-time trust mechanisms for disconnected IoT environments using signed, versioned knowledge packs. Empirical testing on Raspberry Pi 5 with Qwen2.5 models shows a retrieval-score gate achieves 0.97 AUROC in detecting knowledge gaps, though it struggles with in-topic unanswerable queries (0.68 AUROC).
