CREST: Deployment-Realistic Hardware-in-the-Loop NAS for Embedded Sensing Systems

arXiv:2606.15004v1 Announce Type: cross Abstract: Deploying neural networks on low-power microcontrollers (MCUs) requires selecting model architectures under tight memory, latency, and energy constraints. Existing workflows often simplify this process along one or more axes: static proxy costs such as FLOPs or parameters, treating one MCU as representative, and continuous-inference tests instead of deployed sensing schedules. These assumptions can mis-rank Pareto-front candidates, miss infeasible deployments, and obscure schedule-dependent energy. We present CREST (Cross-platform Runtime Evalu

Why this matters
Why now

The proliferation of AI applications demands deployment on edge devices, making efficient hardware-in-the-loop (HIL) neural architecture search (NAS) critical for optimizing performance under tight constraints.

Why it’s important

This research addresses a key bottleneck for deploying advanced AI on low-power embedded systems, enabling more sophisticated and autonomous edge intelligence in various applications.

What changes

Traditional NAS methods that rely on proxies or simplified tests will be less effective, as this approach emphasizes deployment-realistic evaluation, leading to better-performing and more energy-efficient embedded AI.
