Summary
This review compares electroencephalograph (EEG) algorithm accuracy to human experts, finding algorithms less accurate but expert accuracy may be overestimated. Larger datasets are needed for expert-level EEG detection algorithms.
Area of Science:
- Biomedical Engineering
- Signal Processing
- Neuroscience
Background:
- Automated analysis of electroencephalograph (EEG) data is crucial for neurological diagnostics.
- Previous reviews have assessed the state-of-the-art in EEG algorithm development.
- Assessing algorithm performance against human expert interpretation is an ongoing challenge.
Purpose of the Study:
- To review recent advancements in EEG algorithm development.
- To compare the accuracy of various EEG algorithms.
- To evaluate algorithm performance relative to human expert interpretation.
Main Methods:
- Systematic review of 25 manuscripts published since 1975.
- Analysis of novel methods including neural networks and high-resolution frequency techniques.
- Comparison of algorithm accuracy with human expert performance.
Main Results:
- Algorithm accuracy is currently lower than that of human experts.
- Human expert accuracy in EEG interpretation may be lower than commonly perceived.
- Novel methods like neural networks show promise but require further validation.
Conclusions:
- Further development is needed to achieve expert-level performance in EEG detection algorithms.
- Larger and more comprehensive datasets are essential for training and validating advanced algorithms.
- A critical re-evaluation of human expert performance benchmarks may be warranted.
