Machine Learning (ML) models can only be trained in the cloud given their expensive computational and lengthy time requirements in combination with large data sets. Massive processor muscle is applied to deal with both complexity and the required time. It is no surprise that from voice to image to biometric data to autonomous driving is projecting an almost exponential growth in power consumption by datacenters. Hoursec is an AI training and Inference On-Chip that do not depend on the Cloud.
