Abstract
Steady-state visually evoked potentials (SSVEPs) occur due to a repetitive visual stimulus, which results in periodic responses from the visual cortex at the stimulus frequency and its harmonics. Prior studies show that the fundamental SSVEP frequency response can be used to produce a visual reconstruction of what is shown to the human eye. However, due to interference coming from the source and the sensing device, the resulting captured image contains salt-and-pepper noise and random value noise. This study investigates whether information present in the SSVEP harmonics is useful in denoising and enhancing the captured visual reconstruction. The proposed convolutional neural network architecture methods are compared against the SSVEP fundamental and naive additive reconstructions. The results show that combining harmonics and reconstructions from different signal processing methods into the neural network architecture enhances the resulting image.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
