Test deep learning models for 7–32 Hz & 7–40 Hz bandpass filtering to enhance accuracy. Extend ICA: remove components, reconstruct signals, research missing steps, and test impact. Improve EEG channel selection by implementing better algorithms and validating relevance. Address low PSNR; analyze SNR before/after preprocessing and explore additional metrics. Debug pretrained model results; refine code and ensure accurate performance evaluation. Design a hybrid model combining pretrained and custom components for EEG analysis.
