Area of Science:

Neuroscience
Computer Science
Data Science

Background:

Reproducibility is a critical concern in scientific research, particularly in complex fields like machine learning and electroencephalography (EEG).
Estimating mental workload using EEG and machine learning (ML) is a growing area with potential applications but faces challenges in consistent methodology and validation.
Existing efforts in ML and EEG reproducibility provide a foundation for developing standardized guidelines.

Purpose of the Study:

To establish comprehensive guidelines for reproducible machine learning research utilizing EEG data.
To assess the current state of reproducibility in studies focused on predicting mental workload with EEG.
To identify specific challenges and areas for improvement in the reporting and methodology of such research.

Main Methods:

Conducted a systematic literature review of reproducibility in ML and EEG research.
Formulated reproducibility guidelines based on the Cross-Industry Standard Process for Data Mining (CRISP-DM) framework.
Performed a second systematic literature review to evaluate the reproducibility of EEG-based mental workload prediction studies using the established guidelines.

Main Results:

Identified significant limitations in the reporting of performance metrics on unseen test data across reviewed studies.
Found a lack of open sharing for both datasets and source code in many machine learning studies using EEG.
Highlighted insufficient reporting of computational resources required for model training and inference.

Conclusions:

The developed guidelines enhance transparency, collaboration, and knowledge sharing in EEG and ML research.
Adherence to these guidelines can improve the reliability, usability, and overall significance of EEG and ML techniques.
Addressing current challenges in reporting and data sharing is crucial for advancing reproducible mental workload estimation.
