Detailed Description

Language simulation based on the punnets library.

See the paper ``A Pulsed Neural Network for Language Understanding: Discrete-Event Simulation of a Short-Term Memory Mechanism and Sentence Understanding'' for details. In short, we assign one representer neuron (exts) to represent each word. Once fired, a representer neuron periodically fires to keep short-term memory of the word. Representer neurons are interconnected via two networks, named autoassociative network (sgates) and heteroassociative network (dgates). When the network receives several words in a sequence, the two networks computes the bindings of the words, and as a result, the meaning of the input sentence is represented by the activation patter of the representer neurons (synchronized neurons have been bound). The connection weights of the two networks are obtained from the external files.
