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： A method performed by a control node for a radio access network. The control node may select an energy source from a plurality of energy sources connected to a base station based on selecting an energy rate of one of the energy sources correlated in time with a radio traffic power usage of the base station. The selection may be made from a plurality of energy rates for the plurality of energy rates correlated in time for each energy source with a radio traffic power usage of the base station. The selected energy rate may improve at least one operating parameter of the selected energy source. The control node may activate the selected energy source for use by the base station. A further method performed by a global control node may be provided.

摘要： Embodiments described herein provided methods and apparatus for executing a machine-learning model. A first machine-learning model, based on a first set of data and using a machine-learning algorithm, is developed at a first node. A second machine-learning model, based on the first machine-learning model and a second set of data, and using the machine-learning algorithm, is developed at a second node. Information about a difference between the first machine-learning model and the second machine-learning model is communicated from the second node to the first node. A request for execution of a machine-learning model is received at the first node. Responsive to receiving the request for the execution of the machine-learning model, information indicative of an execution policy is obtained at the first node. Finally, depending on the obtained information indicative of an execution policy, either, at the first node, a machine-learning model based on the first machine-learning model and the information about a difference between the first machine-learning model and the second machine-learning model is executed to obtain a result; or the first machine-learning model is partially executed at the first node, and the second machine-learning model is partially executed at the second node, to obtain a result.

摘要： Method and system for Root Cause Analysis (RCA) across multiple network systems are described. Update information of a first local root cause analysis mechanism is received. An RCA controller generates, based on the update information, a new node to be added to a global root cause decision tree, where the global root cause decision tree is to be shared by at least two of the plurality of network operators. The RCA controller requests storage of the new node in a distributed ledger that is shared by network operators. The RCA controller participates in a verification operation of the new node. In response to determining that the verification operation is successful, the RCA controller adds an entry including the new node to the distributed ledger as part of the global root cause decision tree. Alternatively, when the verification operation is not successful, the new node is not added to the distributed ledger.

摘要： A method is proposed for managing a tree-based learner as following. In an initialisation phase: training the tree-based learner with a first set of specimen data to process input data with an active model chain comprising at least a root model to generate an output, each member of the first set of specimen data having a value of each of a first set of features; in an automated reconfiguration phase: receiving a new set of specimen data; performing a comparison between the new set of specimen data and the first set of specimen data; responding to the executed comparison indicating new values of a feature in the new set of specimen data, by reconfiguring the tree-based learner by the addition of a new sub-model to the active model chain, the new sub-model being trained to process at least the new values of the feature.

摘要： There is provided mechanisms for migration of a stateless computation service in a mobile communication network. A method is performed by a control node. The method comprises obtaining, from a core network node in the mobile communication network, information indicative of a need to migrate the stateless computation service from a source compute node in the mobile communication network. The need results from resource utilization at the source compute node is too high, and/or a demand from user equipment for the stateless computation service elsewhere in the mobile communication network. The method comprises initiating migration of the stateless computation service from the source compute node to a target compute node in the mobile communication network for hosting of the stateless computation service at the target compute node.

摘要： Methods and systems automatically protect radio network equipment in extreme weather conditions such as sand-storms or snow-storms. A pair of phase-shift material grids having different orientations is installed at an air intake of the radio network equipment. One of the grids is powered to open or close the air intake according to a current amount of air-carried particles entering the radio network equipment and a temperature inside the radio network equipment. The current amount of air-carried particles entering the radio network equipment may be detected by a piezoelectric sensor.
