1. An artificial intelligence system comprising: at least one interface hierarchy configured to receive an input of a high-dimensional representation and to compress the high-dimensional representation to generate a lower-dimensional representation of the input; at least one processing module configured to receive the lower-dimensional representation and to generate a further representation; at least one control point positioned in a communication path between the at least one interface hierarchy and the at least one processing module, each control point being modulatable between an enabled state in which data is permitted to flow through the control point and a disabled state in which data is inhibited from flowing through the control point; and an action selection controller configured to control communication of the lower-dimensional representation and the further representation between the at least one interface hierarchy and the at least one processing module by modulating the at least one control point.
