TinyML

Machine learning models optimized to run on microcontrollers and resource-constrained devices, enabling AI at the edge with minimal power consumption.

What is TinyML?

Tiny Machine Learning (TinyML) is a specialized field of artificial intelligence that focuses on developing and deploying machine learning models on resource-constrained devices, particularly microcontrollers. These devices typically have limited processing power (often less than 1 MHz), minimal memory (often less than 1 MB), and strict power constraints (often battery-powered or energy-harvesting). TinyML enables AI capabilities on devices like sensors, wearables, and IoT nodes, allowing them to perform tasks such as voice recognition, predictive maintenance, and environmental monitoring without relying on cloud connectivity.
