Abstract: A method for calculating a remaining useful life of an apparatus comprises the following steps. Time-series of previous runs and a current run of the apparatus are provided containing data of sensors configured to monitor parameters of the apparatus. An error occurs when a parameter breaches a threshold. Cumulative counts of errors occurring during a run are calculated. A linearly decreasing remaining useful life is calculated for previous runs. Breakdowns of the apparatus are mapped in an error space. Each dimension of the error space refers to one type of an error. The breakdown points are mapped at coordinates which represent cumulative error counts at the time of the breakdowns. A test point representing cumulative error counts of the current run is mapped. At least two nearest breakdown points to the test point are identified. The remaining useful life of the apparatus is calculated based on the nearest breakdown points.

Abstract: A method detects intrusions in an audit log including records of user sessions with activity features and a user label of a claimed user of the user session. Probabilities that a user session belongs to a user are predicted. A probability is predicted for each combination of a user and a user session of the audit log based on the activity features of the user sessions. A user group including users with similar activity features is constructed based on the predicted probabilities. An anomaly score for a user session of the audit log and a claimed user of the user session belonging to the user group is determined based on a probability that the user session belongs to the user group. An intrusion is detected if the anomaly score of the user session and the claimed user exceeds a predetermined threshold.
