Given the Radial Basis Function that calculates the Euclidean Distance between two points in a plane as the activity value A a Perceptron, where the Perceptron takes $4$ inputs, i$.$e$.,$ for the first point, the x and y coordinates, and for the second point, the x and y coordinates and thus takes $4$ inputs $($see Figure $1)$ and produces the activity value A which is then input into the following activation function:
