    Area of Science:

    • Biomedical data analysis
    • Machine learning in healthcare
    • Neurological disorder detection

    Background:

    • Machine learning (ML) and deep learning (DL) offer advanced biomedical data analysis but require large datasets.
    • Biomedical data collection faces challenges including data quality, privacy concerns, and significant inter-subject variability.
    • Inter-subject variability in biomedical data complicates the identification of population-level differences, particularly in smaller datasets.

    Purpose of the Study:

    • To investigate the efficacy of label alignment techniques in addressing inter-subject variability in EEG-based Traumatic Brain Injury (TBI) classification.
    • To enhance classification accuracy for TBI detection using electroencephalogram (EEG) data.
    • To explore domain adaptation methods for integrating cross-species TBI data to augment training datasets.

    Main Methods:

    • Application of label alignment techniques to EEG datasets for TBI classification.
    • Evaluation of classification accuracy improvements compared to baseline methods.
    • Development of a domain adaptation framework for incorporating data from different species.

    Main Results:

    • Label alignment techniques demonstrated a notable increase in TBI classification accuracy, with improvements of up to 6% in certain cases.
    • The study successfully addressed challenges posed by inter-subject variability in EEG data.
    • A methodology for domain adaptation to include TBI data from other species was proposed.

    Conclusions:

    • Label alignment is an effective strategy for mitigating inter-subject variability in EEG-based TBI classification, leading to improved diagnostic performance.
    • The proposed domain adaptation approach offers a pathway to expand training datasets by leveraging cross-species data, potentially further boosting model performance.
    • These findings contribute to advancing ML applications in neurology and TBI diagnostics.
