Publication number: 20230135745Abstract: According to an example embodiment, a device is configured to a deep reinforcement learning, DRL, agent to simulate the behaviour of a network component. The DRL agent takes the network state and user traffic as inputs. It generates the next network state and user performances. A training algorithm of the simulator is configured for the DRL agents and it is derived to deal with the property of time-correlation in network components. The simulator uses a training algorithm so that it enables robust inference under a limited number of transitions collected with the real network components and users. It is derived with state augmentation by using an autoencoder architecture. It is also configured by a reward estimation algorithm by using local regression, for example with a Gaussian Process.Type: ApplicationFiled: October 12, 2022Publication date: May 4, 2023Inventors: Qiang LIU, Nak Jung Choi
