A method performed by a master node operable in a communication network for predicting one or more metrics associated with the communication network, the method comprising: - receiving, from local nodes in the communication network, one or more predictions based on training data, - determining one or more weight parameters associated with the local nodes based on one or more received predictions and one or more previously received predictions, the one or more weight parameters indicating a relevance of predictions received from individual ones of the local nodes, and - adjusting a respective local reporting policy for one or more of the local nodes based on the one or more determined weight parameters, wherein the local reporting policy comprises information instructing a local node of the one or more local nodes how to send one or more predictions, and wherein the adjusting of the respective local reporting policy for the one or more local nodes comprises: ▪ deactivating a local node of the one or more local nodes, the local node having a determined weight parameter not meeting a first threshold, wherein the local node will stop to send predictions to the master node; and/or ▪ activating a local node of the one or more local nodes, the local node having previously been deactivated, wherein the local node will start to send predictions to the master node; and/or ▪ changing the frequency with which a local node of the one or more local nodes transmits predictions to the master node; and/or ▪ turning off the sending of the predictions from a local node of the one or more local nodes so that the local node just sends raw data. - receiving, from local nodes in the communication network, one or more predictions based on training data, - determining one or more weight parameters associated with the local nodes based on one or more received predictions and one or more previously received predictions, the one or more weight parameters indicating a relevance of predictions received from individual ones of the local nodes, and - adjusting a respective local reporting policy for one or more of the local nodes based on the one or more determined weight parameters, wherein the local reporting policy comprises information instructing a local node of the one or more local nodes how to send one or more predictions, and wherein the adjusting of the respective local reporting policy for the one or more local nodes comprises: ▪ deactivating a local node of the one or more local nodes, the local node having a determined weight parameter not meeting a first threshold, wherein the local node will stop to send predictions to the master node; and/or ▪ activating a local node of the one or more local nodes, the local node having previously been deactivated, wherein the local node will start to send predictions to the master node; and/or ▪ changing the frequency with which a local node of the one or more local nodes transmits predictions to the master node; and/or ▪ turning off the sending of the predictions from a local node of the one or more local nodes so that the local node just sends raw data. ▪ deactivating a local node of the one or more local nodes, the local node having a determined weight parameter not meeting a first threshold, wherein the local node will stop to send predictions to the master node; and/or ▪ activating a local node of the one or more local nodes, the local node having previously been deactivated, wherein the local node will start to send predictions to the master node; and/or ▪ changing the frequency with which a local node of the one or more local nodes transmits predictions to the master node; and/or ▪ turning off the sending of the predictions from a local node of the one or more local nodes so that the local node just sends raw data.
