摘要: The Hypercube-based NeuroEvolution of Augmenting Topologies (HyperNEAT) approach demonstrated that the pattern weights across connectivity an artificial neural network (ANN) can be generated as a function its geometry, thereby allowing large ANNs to evolved for high-dimensional problems. Yet it left user question where hidden nodes should placed in geometry is potentially infinitely dense. To relieve from this decision, paper introduces extension called evolvable-substrate HyperNEAT (ES-HyperNEAT) determines placement and density based on quadtree-like decomposition hypercube novel insight about relationship between node placement. idea representation encodes ANN contains implicit information therefore exploited avoid need evolve explicit In paper, proof concept, ES-HyperNEAT discovers working placements simple navigation domain own, eliminating configure substrate by hand suggesting potential power new approach.
