About the Project

Brain development can be evaluated by experts analysing age-related patterns in sleep electroencephalograms (EEG). Natural variations in the patterns, noise, and artefacts affect the evaluation accuracy as well as experts’ agreement. The knowledge of predictive posterior distribution allows experts to estimate confidence intervals within which decisions are distributed. Bayesian approach to probabilistic inference has provided accurate estimates of intervals of interest. The project aims to explore new feature extraction techniques for the Bayesian assessment and reliable estimation of predictive distribution in the model’s outcomes. The new models will be verified on a large EEG data set including 1,100 recordings made from newborns. The designed features are expected to be highly correlated with the brain maturation and increase the assessment accuracy.

Research questions: (1) to explore the ability of a designed strategy of Machine Learning to extend the EEG-based brain development assessment (2) to explore ways of designing decision models within the Bayesian framework.
