The task of the detector ANN is to correctly classify the inputs from the left and right sides of the retina as valid or not by producing a vector of the binary outputs with values of 0.0 or 1.0. The output vector has a length of 2, which is equal to number of the output nodes.
We can define the detection error as the Euclidean distance between the vector with ground truth values and the vector with ANN output values, as given by the following formula:
is the squared detection error for one trial, is the vector ...
