H2E: Deterministic Safety via Riemannian Multimodal Fusion
H2E framework fuses text/audio/vision inputs from compressed models into a Riemannian manifold, enforcing safety with SROI Gate that rejects intents where exp(-d_M) < 0.9583, guaranteeing deterministic, auditable AI behavior on edge hardware.
Compressed Models Enable Edge Multimodal Processing
Achieve expert-level reliability on restricted hardware using three quantized models: Sarvam-30b for text (FP8 quantization, METEOR score 0.9964), Voxtral-Mini-4B for audio-to-text (3% word error rate in real-time), and Gemma 4 E4B for vision (2.63 GB RAM). These process sensory inputs—text, audio, vision—into a unified representation, avoiding black-box unpredictability by prioritizing efficiency without sacrificing performance. This setup allows deployment on edge devices while handling complex multimodal data.
Riemannian Geometry Enforces Hard Safety Bounds
Project all modalities onto a Riemannian product manifold M = H² × SPD(3) to compute geodesic distance d_M between AI intent and a safe submanifold. The SROI Gate acts as a circuit breaker: if exp(-d_M) ≥ 0.9583, the intent proceeds to the cognitive layer; otherwise, it's rejected outright. This geometric governance creates a deterministic "Riemannian Hard Stop," ensuring only safe intents generate responses, eliminating stochastic hallucinations through eager execution and fixed seeds for reproducible outcomes.
Audit Trails and Energy Tracking for Sustainable Governance
Assign a Deterministic Audit Hash to every interaction, providing a traceable record of manifold-based reasoning for full transparency. Integrate carbon intensity monitoring to track energy use, setting a benchmark for eco-friendly AI. Fixed seeds guarantee identical inputs yield identical safe outputs, making the system suitable for safety-critical applications while remaining accessible on edge hardware.
