... Over time (e.g. during sentence processing), the activation of neurons/clusters changes. These changes can be modeled with Recurrent Neural Networks [Elman, 1991]: • the model is defined in terms of a ‘context’ vector of neural units, as shown above; • activation of the context vector defines a ment ...
