Abstract: Example implementations described herein involve integrating human observations into results of a machine learning process to generate an integrated failure prediction and updated machine learning models from human observations. Example implementations can involve systems and methods that, for receipt of a user input indicative of a failure symptom at a facility, conducting cause estimation on the failure symptom to determine a first set of probabilities associated with a first set of causes of the failure symptom; and integrating the first set of probabilities and first set of causes into a process configured to provide a second set of probabilities and a second set of causes of the failure symptom based on a set of potential failures associated with a third set of probabilities provided from a machine learning process configured to output the set of potential failures and the third set of probabilities based on sensor data from the facility.
