The background value of the grey derivative d[X.sup.(1).sub.1] (rp + t)/dt is taken as the mean of [X.sup.(1).sub.1] (rp + t) and [X.sup.(1).sub.1] (rp + t - 1), and those of the associated series Xp1 (t) are also taken as the mean of [X.sup.(1).sub.i] (t) and [X.sup.(1).sub.i] (t - 1) for i = 2, 3, ..., n, respectively, in the determination of model parameters by GMC (1, n).

The output layer simply divides the output of the S-summation neuron by the output of the D-summation neuron, giving the prediction value for an input vector or pattern [X.sub.p]: xp1.....xp,.....xpN, using the following expression:
We used Kodak Ektachrome 200 or 400, or Fujichrome Pro-via 400, which are color positive films, or occasionally (in 1985) Ilford XP1 black-and-white negative film pushed to ISO (ASA) 1600.

Yet, if probe P has both the [+[??]] feature and the [+EPP] feature, the case position of XP is XP1. This is the situation with the direct object in example (61) and other similar cases, where "shallow" Reconstruction places the direct object back in its case position, [spec, v].
