Tool to extract biomarkers from electroencephalogram signals

13 November, 2023

electroencephalogram signals

Through the extraction of electroencephalogram signals and the use of artificial intelligence and machine learning techniques, the SignalEEG tool is responsible for the treatment, processing and modeling of signal data, especially wearable and EEG signals, in order to build predictive models for the detection of different mental health diseases: brain, neurological and cognitive disorders. 

Specifically, the group has developed and implemented these techniques in different scenarios: schizophrenia prognosis, alcoholism, stress detection and emotion recognition. In the case of the latest, the aim is to detect negative emotions of people through brain changes, which are measured through EEG signals, to prevent the emergence of mental health problems. 

The tool interface is user-friendly, easy to use and multiprocess, with functionalities for all steps of data mining: noise filtering, windowing, feature extraction, feature selection, shaping, data balancing, validation methods, visualization, among others. 

This technology has been used in the development of several projects, such as SERAS (in collaboration with a private company), with the aim of improving the living conditions of patients with epilepsy through early crisis detection.
