Electroencephalography (EEG) is a critical tool in neurocritical care for detecting seizures and other forms of harmful brain activity in critically ill patients. However, the current reliance on manual analysis by specialized neurologists presents significant challenges, including time consumption, high costs, fatigue-related errors, and inter-reviewer reliability issues. The HMS - Harmful Brain Activity Classification research aims to address these limitations by developing automated machine learning models for EEG pattern classification.
The fundamental objective of this research is to enhance the accuracy and efficiency of EEG analysis in clinical settings. By developing complex algorithms, the project seeks to assist healthcare professionals in rapidly identifying and classifying six key patterns of brain activity: seizures (SZ), generalized periodic discharges (GPD), lateralized periodic discharges (LPD), lateralized rhythmic delta activity (LRDA), generalized rhythmic delta activity (GRDA), and other non-specific patterns. The research utilizes a dataset of EEG recordings from critically ill hospital patients, annotated by a panel of expert neurologists. This dataset is unique in its comprehensive representation of various brain activity patterns, including:
Idealized patterns: EEG segments with high levels of expert agreement on classification. Proto patterns: Cases where approximately half of the experts classify the segment as one of the five specific patterns, while the other half label it as “other” Edge cases: Segments where expert opinions are split between two of the five named patterns.
This diverse dataset allows for the development of robust models capable of handling a wide spectrum of EEG presentations, from clear-cut cases to more ambiguous scenarios that challenge even human experts.
We are challenged to design machine learning models that can well predict the probability distribution of expert votes for each EEG segment across the six classification categories. This not only aims at emulating expert consensus but also at capturing intrinsic uncertainty in EEG interpretation, especially when dealing with edge cases or proto-patterns. The project makes use of the Kullback-Leibler (KL) divergence as
The primary metric for measuring evaluation is the difference between the probability distribution predicted by the model and the target distribution of expert votes, as observed.
