Figure 4.12
A simple pattern associator.The example assumes that patterns of activation in the A units can by
produced by the visual system and patterns in the B unit can be produced by the olfactory system.
The synaptic connections allow the outputs of the A units to influence the activations of the B units.
The synaptic weights linking the A units to the B units were selected so as to allow the pattern of
activation shown on the A units to reproduce the pattern of activation shown on the B units without
the need for any olfactory input.
Figure 4.13
Two simple associators represented as matrices.The weights in the first two matrices allow the A
pattern shown above the matrix to produce the B pattern shown to the right of it.Note that the
weightsinthe first matrix arethe same as thoseshown in thediagram in figure4.12.
