Fig. 2: SEL architecture.

There are two main components of SEL: one for interaction with the environment and the other for decision-making. a The actor is a device that modifies the surrounding EM environment. b The perception module transforms the environmental state into an internal representation. c The steering network provides supervision for achieving goals. d The semi-supervised controller generates decisions in accordance with the supervised parameters from the steering network and local knowledge. e The motor, which executes the decisions generated by the controller, drives the actor to change its state to, in turn, affect the environment. f The evolutionary module evolves the steering network and the stored local knowledge based on the data collected during operation.
