摘要： A computer implemented method for configuring a reinforcement learning agent to perform an efficient reinforcement learning procedure, wherein the reinforcement learning agent comprises a model trained using a machine learning process to determine actions to be performed by the reinforcement learning agent. The method comprises using (202) the model to determine an action to perform, based on values of a set of features obtained in an environment; determining (204), for a first feature in the set of features, a first indication of a relative contribution of the first feature, compared to other features in the set of features, to the determination of the action by the model; and determining (206) a reward to be given to the reinforcement learning agent in response to performing the action, based on the first feature and the first indication.

摘要： In one aspect, a method of determining a risk of conflict between a movable device and potential obstacles is provided. The method comprises dividing a space into a plurality of positions. At each of a plurality of successive times, the method further comprises: determining a conflict function for the movable device in a first position at a respective time, the first position having one or more neighbouring positions, wherein the conflict function is determined based on whether or not an obstacle is present in any of the first position and the one or more neighbouring positions; and determining a respective risk value for at least one of the first position and the one or more neighbouring positions using the conflict function and a risk value associated with a second position, wherein the movable device is planned to move from the first position to the second position at a subsequent time.

摘要： A method performed by a risk management node for autonomous devices. The risk management node may determine state parameters from a representation of an environment. The representation of the environment may include an object, an autonomous device, and a set of safety zones. The risk management node may determine a reward value based on evaluating a risk of a hazard with the object based on the determined state parameters and current location and speed of the autonomous device relative to a safety zone from the set of safety zones. The risk management node may determine a control parameter based on the determined reward value, and may initiate sending the control parameter to the autonomous device to control action of the autonomous device. The control parameter may be dynamically adapted to reduce the risk of hazard with the object based on reinforcement learning feedback from the reward value.

摘要： A Cognitive Manager (CM) controls a RAN. The CM obtains from the RAN a set of local needs identifying a radio communication performance criterion that is to be satisfied. A set of neighbor needs are obtained from a neighbor CM. An event message is received from the RAN containing a radio metric that does not presently satisfy at least one of the set of local needs. A set of present neighbor improvement action drives being performed or will be performed to satisfy the set of neighbor needs, are obtained from the neighbor CM. A combination of the set of local needs, the set of the neighbor needs, the set of present neighbor improvement action drives, and the radio metric, is used to determine a local improvement action drive that is to be performed by the RAN. An adjustment report identifying the local improvement action drive is provided to the RAN.

摘要： According to an aspect, there is provided a computer-implemented method performed by a management node for use with a cognitive layer (CL). The CL is used to improve or manage a system. The CL comprises a plurality of agents. The agents have respective agent information, the respective agent information indicating one or more types of input data required by a model implemented by the agent, one or more parameters of the system that are to be improved by the agent, one or more types of output data provided by the model implemented by the agent and a data distribution for the agent. The method comprises (i) selecting (301) a set of similar agents from the plurality of agents that improve a first parameter of the system, wherein similar agents are selected on the basis of similarities or matches in the one or more types of input data, the one or more types of parameters of the system improved by the agent, and the one or more types of output data; (ii) for a first agent and a second agent in the selected set of similar agents, comparing (302) the data distribution for the first agent to the data distribution for the second agent to determine a relationship between the data distributions; (iii) initiating (303) generation of one or more candidate agents based on the determined relationship; and (iv) determining (304) whether to replace one or both of the first agent and the second agent with the one or more candidate agents based on a comparison of a performance of the one or more candidate agents with respect to a performance of the first agent and/or a performance of the second agent.

摘要： Methods and apparatus for implementing reinforcement learning are provided. A method in a client node that instructs actions in an environment in accordance with a policy comprises identifying one or more critical states of the environment for which a current policy provides unreliable actions. The method further comprises initiating transmission to a server of a retraining request, the retraining request comprising information relating to the one or more critical states. The method further comprises receiving a new policy from the server, wherein the new policy is generated by the server using reinforcement learning based on the information relating to the one or more critical states, and instructing actions in the environment in accordance with the new policy.
