Abstract: In order to provide a control apparatus achieving an efficient control of network using a machine learning, a control apparatus includes a learning unit and a control unit. The learning unit learns an action for controlling the network. The control unit controls the network by setting a control parameter to an apparatus included in the network based on an action obtained from a learning model generated by the learning unit. The control unit decides the control parameter based on an influence of the action obtained from the learning model on a state of the network.
