    Abstract: Methods and apparatus for root cause analysis. A method comprises obtaining measurement data comprising measurements data of features of a system. The method further comprises generating a prediction value by applying a trained machine learning model to the measurement data, and also generating feature impact values by applying a generated machine learning model explainer to the measurement data. The method further comprises updating an ontological representation of connections between the features of the system and the prediction value using the generated feature impact values and, based on the updated ontological representation, outputting a proposed root cause that is responsible for the prediction value.

    IPC: G01S5/02

    Abstract: A technique for calibrating a positioning system comprising a plurality of anchor nodes used to determine tag positions within a localization area using radio technology is disclosed. A method implementation of the technique is performed using a measurement device comprising at least one odometry sensor and a localization tag configured to communicate with the plurality of anchor nodes using the radio technology. The method comprises performing (S202), at a plurality of first measurement points in the localization area using the localization tag, first ranging measurements with respect to the plurality of anchor nodes using the radio technology to determine respective first distances from the measurement device to the plurality of anchor nodes and performing, at the plurality of first measurement points using the at least one odometry sensor, first odometry measurements to estimate respective first positions of the measurement device in the localization area, estimating (S204) locations of the plurality of anchor nodes based on the respective first distances determined by the first ranging measurements and the respective first positions estimated by the first odometry measurements, and configuring (S206) the positioning system with the estimated locations of the plurality of anchor nodes to calibrate the positioning system.

    Abstract: There is provided a method for assessing network performance. The method comprises acquiring (102) network measurements indicative of any changes in a network following a change to a configuration of the network and data indicative of one or more factors capable of causing the changes in the network. The one or more factors are independent of the change to the configuration of the network. The method comprises analysing (104) the acquired network measurements and data to identify a contribution of the one or more factors to a key performance indicator (KPI) and a contribution of the change to the configuration of the network to the KPI. The KPI is predicted by a machine learning model and is a measure of the network performance following the change to the configuration of the network.
