Hands-On Neuroevolution with Python

Objective function definition

The main task of the visual discriminator is to correctly determine the position of a larger object regardless of the relative positions of both objects. Thus, we can define the objective function to guide the neuroevolution process. The objective function should be based on the Euclidean distance between the exact position of the larger object in the visual field and its predicted position in the target field.

The loss function can be directly represented as the Euclidean distance between the actual and predicted positions as follows:

is a loss function, is the ground truth coordinates of the big object, and ...
