Abstract
Spiking Auto-Encoders (SAEs) have the potential to greatly outperform deep learning auto-encoders in power efficiency, yet their performance remains a challenge. This work enhances both power efficiency and accuracy by reducing spike counts and introducing key innovations. We propose a novel decoder neuron model that enables precise spike timing and implement a weight-dependent Spike-Timing-Dependent Plasticity (STDP) mechanism in the encoder for better feature learning. Our architecture encodes static MNIST images using only a single spike and reconstructs spatio-temporal data from the Spiking Heidelberg Digits (SHD) dataset, optimizing the spike count for reconstruction. This substantial reduction in spike usage translates to a marked improvement in power efficiency. In addition, the average Mean Square Error (MSE) for the MNIST images was found to be 0.039, representing a 99.93% reduction from previous results. These improvements advance neuromorphic systems toward more practical, efficient applications.

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
