Overview
What it means
TinyML compresses models through quantisation, pruning and efficient architectures so they run on battery or energy-harvesting devices for months or years. A dedicated research community and industry foundation coordinate methods, benchmarks and tools.
How it is used
Flagship uses are distributed environmental sensing: acoustic monitors recognising chainsaws or species in forests, low-power camera traps, soil and water sensors, and smart-meter analytics — all without mains power or connectivity.
Why it matters
TinyML expands the observable world: it puts pattern recognition where infrastructure is absent and where conservation and agriculture actually happen. It is also the efficiency endgame of AI — capability per milliwatt as the design target.
