Robotic implementation of classical and operant conditioning within a single SNN architecture
Bibliographic record
Abstract
This work presents the implementation of operant conditioning (OC) and classical conditioning (CC) with a single spiking neural network (SNN) architecture, thus suggesting that the two types of leaning may relate to the same cognitive process. Both are achieved by using a modified version of spike-timing-dependent plasticity (STDP), where the connection weight between a cue neuron and an action neuron depends on the temporal relation between their spikes and those of a reward neuron. This reward driven STDP (RD-STDP) was implemented with simple computational resources to form an electronic robot's brain, using an adaptation of the synapto-dendritic kernel adapting neuron (SKAN) model. Then, a robot driven by the new neuronal architecture was tested in a maze with changing features, successfully exhibiting CC and OC. These results and the simple computational resources used make the proposed architecture promising for very large scale time-dependent parallel data analysis, with high capacity of adaptation in a dynamic environment. Moreover, it proposes a theoretic framework to model learning by conditioning.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
