Notes on Machine Learning on edge for embedded/sensor/IoT uses
A computer with a modern GPU for machine learning is approx 1000 USD. The state-of-the-art ML models that in the mainstream attention are getting ever larger. Currently being led by Large Language Models and Generative Image models. Requiring more compute and RAM every year.
TinyML is a whole nother beast - with a focus on tiny models that can run on small,power-efficient and low-cost microcontrollers. Low cost enables massive scale.
