This study introduces a novel EEG framework using Chaotic Pattern of Prime Numbers (CPPN) features to predict depression treatment response. The method demonstrates high accuracy and surpasses traditional EEG features, offering a robust basis for future studies.

Area of Science:

Neuroscience
Computational Psychiatry
Biomedical Engineering

Background:

Predicting depression treatment response remains challenging.
Electroencephalography (EEG) offers potential biomarkers for treatment outcomes.
Existing EEG feature extraction methods may lack robustness and interpretability.

Purpose of the Study:

To develop and validate a novel EEG framework for depression treatment-response modeling.
To introduce Chaotic Pattern of Prime Numbers (CPPN) as a new EEG feature representation.
To establish a rigorous validation hierarchy for assessing feature performance and model generalizability.

Main Methods:

A validation-aware framework was developed using CPPN features.
EEG data from SSRI and rTMS cohorts were analyzed.

A seven-protocol validation hierarchy was employed, including segment-level and subject-level cross-validation.

Feature selection methods like Normalization and NCA ranking were integrated.

Main Results:

CPPN features demonstrated strong discriminative power, achieving high accuracies (e.g., 99.42%) in segment-level cross-validation.
CPPN features significantly outperformed conventional EEG features (by up to 29.53 percentage points).
Subject-wise validation yielded more conservative but still promising results (best LOSO accuracy 80.00%).

Conclusions:

CPPN offers a compact, inspectable, and computationally accessible EEG feature representation.
The proposed validation hierarchy provides transparent evaluation of performance across different validation depths.
This methodological contribution offers a rigorous foundation for future EEG-based treatment-response studies.
