TinyML: Machine Learning on Microcontrollers

Microcontrollers, miniature computers that can run simple commands, are the basis for billions of connected devices, from internet-of-things (IoT) devices to sensors in automobiles.

Tiny machine learning involves running edge ML algorithms on very small, energy-efficient devices like microcontrollers and simple sensors. Instead of sending data back and forth to the cloud, these devices can process information directly where it is generated.

Industries are increasingly focusing on tiny machine learning because of its advantages over cloud-only methods. Computation happens directly on the device, enabling instant responses without relying on the cloud. These models run on microcontrollers that consume only a fraction of the energy used by traditional processors.

Training a machine-learning model on an intelligent edge device allows it to adapt to new data and make better predictions. For instance, training a model on a smart keyboard could enable the keyboard to continually learn from the user’s writing. However, the training process requires so much memory that it is typically done using powerful computers at a data center, before the model is deployed on a device.

To address this problem, researchers have developed new techniques that enable on-device training using less than a quarter of a megabyte of memory. The intelligent algorithms and frameworks the researchers developed reduce the amount of computation required to train a model, which makes the process faster and more memory efficient. This technique also preserves privacy by keeping data on the device, which could be especially beneficial when data are sensitive, such as in medical applications. It also could enable customization of a model based on the needs of users.
