Tiny ML in Microcontroller to Classify EEG Signal into Three States

This thesis investigates how to implement an own-built neural network for electroencephalography signals classification on an STM32L475VG microcontroller unit. The original dataset is analyzed and processed to better understand the brain signals. There is a comparison between three machine learning algorithms (linear support vector machine, extreme gradient boosting, and deep neural network) in three testing paradigms: specific-subject, all-subject, and adaptable to select the most appropriate approach for deploying on the microcontroller. The implementation procedure with detailed notation is presented, and the inference is also performed to feasible observation. Finally, possible improvement solutions are proposed within a clear demonstration.This thesis investigates how to implement an own-built neural network for electroencephalography signals classification on an STM32L475VG microcontroller unit.
