摘要： A method includes receiving input data including a plurality of feature vectors and labeling each feature vector based on a temporal proximity of the feature vector to occurrence of a fault. Feature vectors that are within a threshold temporal proximity to the occurrence of the fault are labeled with a first label value and other feature vectors are labeled with a second label value. The method includes determining, for each feature vector of a subset, a probability that the label associated with the feature vector is correct. The subset includes feature vectors having labels that indicate the first label value. The method includes reassigning labels of one or more feature vectors of the subset having a probability that fails to satisfy a probability threshold and, after reassigning the labels, training an aircraft fault prediction classifier using supervised training data including the plurality of feature vectors and the labels.

摘要： A system (200) for monitoring aircraft operational messages is provided. The system (200) includes a computing device (210) including a processor (305) in communication with a memory (310). The computing device (210) is programmed to receive a plurality of historical messages for a plurality of aircraft (225). Each message of the plurality of historical messages is a message from one of the plurality of aircraft (225). The computing device (210) is also programmed to receive a plurality of historical maintenance operations performed on the plurality of aircraft (225), compare the plurality of historical messages to the plurality of historical maintenance operations to determine at least one message type associated with at least one maintenance operation type, and generate a plurality of message type correlations between message types and maintenance operation types based on the comparison.
