Spiking Temporal Memory

Overview

This repository contains a detailed mathematical description and a reference implementation of the spiking Temporal Memory (sTM) model, originally developed by Bouhadjar et al. (2022). ... Various flavors of the model have been used in a number of follow-up studies (Bouhadjar et al. (2023a), Bouhadjar et al. (2023b), Siegel et al. (2023a), Siegel et al. (2023b), Bouhadjar et al. (2025)).

Model description

A detailed mathematical, implementation agnostic description of the model and its parameters is provided here.
