Abstract
Neuromorphic computing envisions the realization of a hardware neural network mimicking the brain's energy efficiency and rapid information processing. Leveraging the multifunctional capabilities of core neuromorphic building blocks offers an efficient approach to developing compact and intelligent hardware systems. This article demonstrates a novel technique to employ a graphene memristor‐based leaky integrate‐and‐fire circuit, which is hereby referred to as Spikoder. This circuit not only functions as a dynamic encoder transforming continuous input signals into spike sequences but also operates as a neuron circuit with reduced topological complexity. The circuit exhibits exceptional spike‐encoding performance, validated using spike‐encoded images from the Modified National Institute of Standards and Technology dataset. The effectiveness of this encoding technique is evaluated through experiments on single‐layer and double‐layer fully connected spiking neural networks (SNNs). The single‐layer SNN utilizing the dual‐mode neuron circuit achieves a high image recognition accuracy of 90.77%, while the implementation of a double‐layer SNN increases the test accuracy to 97.37%, further demonstrating its scalability for high‐level neuromorphic computing. This research highlights the possibility of using the hybrid encoder‐neuron circuit as an efficient and scalable solution for advanced neuromorphic computing hardware.

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
