A new framework called ENAS has been introduced to optimize Neural Architecture Search for microcontrollers. It uses a hardware-aware approach and a hybrid search strategy to improve efficiency without needing GPUs.

Key facts

ENAS is a Neural Architecture Search framework designed for hardware efficiency in resource-constrained environments.
The framework features a static feasibility check and a cell-based search space that supports various block types and skip connections.
ENAS employs a three-stage hybrid search strategy with persistent cross-run caching, operating without GPU acceleration.
Evaluations were conducted on two TinyML benchmarks across eight microcontrollers with SRAM footprints from 20 KB to 1 MB and nine input image resolutions.
ENAS demonstrated mean search-time speedups on Visual Wake Words and Melanoma Cancer compared to NanoNAS.
