Abstract: A computer-implemented method, system, and computer program product for classifying a sequence of log entries of a computing system may be provided. The method may include pre-processing the log entries. The method may also include predicting, as a first output of a first trained machine-learning system, a likelihood of a particular next log entry after the window. The method may also include, predicting, as a second output of a second trained machine-learning system, whether the next log entry is unprecedented. The method may also include combining the first output and the second output for determining a classification of the sequence of log entries.
