| Abstract(in English) | Modified Hebbian learning rule (Griniasty et al. 1993) or trace mechanism (Foldiak 1992)is one account for the problem of how the temporal relations among events are represented in neural connections. Here we show another possibility to consider random encoding strategy in which items to be stored are associated with the randomly chosen attractors of a network independent of spatial relationships between them. Namely the network spontaneously generate random patterns of activity as internal representations for events or objects. This was demonstrated by the network models in which connection weights are i.i.d.random variables under the symmetric condition. Mathematical properties on this system, such as distances between randomly chosen attractors, methods generating the random patterns and the dependencies of the methods, are theoretically considered. Lastly, we discuss its relevances to the physiological evidences for memory. |
