Ai
Examples of ai7 networks whose architecture as well as weights are open to selection pressure and ai's custom evolutionary operators. Here shown are a XOR network (left) and a SIN network (right). The small graph on the right of each network maps the actual network output (black dots) against the target/desired output (red dots). Blurry pink spots represent input neurons, yellow stand for output neurons, and grey for hidden or inter- neurons. Arching lines ("axons") represent connections between the neurons, and their intensity indicate the weight of the connection. The sign of the weight is indicated by colour: red for negative and blue for positive. The direction of the connection is indexed by a gentle "dip" into the post-synaptic neuron.
