Exercise 7.18

Answers

(a): For a given $ϕ_{k} (x)$ , for the white pixels in the feature, we set $w_{ij} = 0$ , and for the black pixels in the feature, we set $w_{ij} = 1$ or some positive number, if the input $x$ has the same feature, we will have $ϕ_{k} (x) = 1$ .
(b): The inputs to the neural network node are the pixel values, i.e. $[x_{ij}]$ matrix
(c): See problem (a).
(d): I will choose $w_{0}$ as random gaussian distributed with mean 0 and variance of 1.
