Original Abstract Submitted
A method and device for constructing a decision tree for diagnosing a system with components. The method includes obtaining a training data set comprising pairs with a vector of measured values of observable variables representing a system operation and a label. The label represents a nominal operating state of the system or a failure state of one component. The method includes processing a current node created by splitting a previous node and associated with a subset of the training data set as a current data set. When a splitting criterion is satisfied, splitting the current node into a first and a second child node by applying a classification function obtained from the current data set and defined to a nominal class representing the nominal operating state of the system or a failure class representing the failure states of the system. The method includes providing a decision tree for system diagnosis.
