For instance, in the initial state, some of the qi may be put equal to 0 but then via the process of associative memory, the qj acquire final values which fill in the gaps in the state vector describing the specific pattern. 6) where we have used the abbreviation D = (B +C) ~ k' d· . 7) This leads us to construct the following network (Fig. e. the cell j receives the input qj(O). Each incoming value qj(O) is multiplied by a connectivity v~ and the sum of these values is taken over all indices j.

B) Let the index u beL+ 1, ... ,M and u' = 1, ... ,L so that ~u = 0 ~u' = ±~o u=L+1, ... M u' = 1, ... 64) c) We now make the following choices ~u =0 ~u' =0 = L + 1, ... M u' = L + 1, ... M u . 66) and a2 v --=0, a~ua~u' u*u'. 69) below, but with K = 0. 68) In order to discuss the definiteness of this matrix we require that the following determinant vanishes C-K B+C B+C ... B+C B+C C-K B+C ... B+C B+C B+C C-K ... 69) B+C B+C B+C ... 68). 69) directly, we consider instead the corresponding eigenvector equations (5.

49) which allows a discrimination of the roll patterns in fluids. 14) and then has to be taken into the sum. But for the time being such a generalization is not needed. 13). This meaning will become more transparent during the course of the book. k are called attention parameters. We shall see that a pattern can be recognized only if the corresponding attention parameters are positive; otherwise it will not be recognized. The expression vk · v [ acts as a matrix. As one can see, first v [ is multiplied by a column vector q so that a scalar is generated.
