Abstract
Conventional surrogate Back-Propagation-Through-Time learning in Spiking Neural Networks (SNN) demands excessive energy consumption when simulating over extended time intervals. Moreover, the spike encoding process necessitates intricate hardware support, thus undermining overall efficiency. Additionally, their classification accuracies fall short in comparison to artificial neural networks due to the inherent information loss in spike translation. Therefore, there is a critical need for efficient techniques that can enhance performance without compromising accuracy. In this study, we introduce a novel learning scheme that harnesses lossless phase coding. This approach allows us to achieve minimal inference latency, requiring a maximum of at most 8 simulation steps. Furthermore, our training times exhibit significant reductions when compared to previous single-spike networks. Our experimental results demonstrate that Phase-SNN attains state-of-the-art accuracy levels, achieving 98.6% and 89.6% accuracies on the MNIST and Fashion-MNIST datasets, respectively.

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
