Leaky-Integrate-and-Fire Neuron-Like Long-Short-Term-Memory Units as Model System in Computational Biology
Bibliographic record
Abstract
Biological neural networks encode information very efficiently, and dynamically react to sensory input on very small time scales. In contrast to most contemporary machine learning approaches which rely on rate neurons with continuous output, biological neural networks are based on spiking neurons with quasi-binary discrete output. In Artificial Intelligence (AI) Research, time series data are efficiently encoded in Long-Short- Term-Memory (LSTM) networks. Despite their strength in encoding time series data and making predictions, LSTM units are assumed to be biologically implausible. Nevertheless, recent studies show that LSTM unit networks indeed behave similar to biological neural networks. In this study, we show that a particular choice of parameters for the weights and gates in peephole LSTM units causes these units to show similar dynamic behaviour as biologically plausible leaky integrate-and-fire (LIF) neurons, which represent a simple biologically inspired spiking neuron model. We analyzed the spiking characteristics of the restricted peephole LSTM units and characterize the parameter space, in which these units show certain spiking characteristics. We conclude that tackling complex cognitive tasks with biologically plausible and explainable artificial neural networks is an important step to make progress in both fields, neuroscience and artificial intelligence.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
