Developmental Encodings in Neuroevolution - No Free Lunch but a Peak at the Menu is Allowed

Kiran Manthri, Bala, Sai Tanneeru, Kiran January 2021 (has links)
NeuroEvolution besides deep learning is considered the most promising method to train and optimize neural networks. Neuroevolution uses genetic algorithms to train the controller of an agent performing various tasks. Traditionally, the controller of an agent will be encoded in a genome which will be directly translated into the neural network of the controller. All weights and the connections will be described by their elements in the genome of the agent. Direct Encoding – states if there is a single change in the genome it directly affects a change in the brain. Over time, different forms of encoding have been developed, such as Indirect and Developmental Encodings. This paper mainly concentrates on Developmental Encoding and how it could improve NeuroEvolution. The No-Free Lunch theorem states that there is no specific optimization method that would outperform any other. This does not mean that the genetic encodings could not outperform other methods on specific neuroevolutionary tasks. However, we do not know what tasks this might be. Thus here a range of different tasks is tested using different encodings. The hope is to find in which task domains developmental encodings perform best.
