1. A computer-implemented method of performing failure signature recognition training, the method comprising:
- by one or more processors and associated memory;
receiving;
(i) sensor data relating to at least one unit of equipment and (ii) failure information relating to equipment failures;
analyzing the received sensor data in view of the received failure information, the analyzing being automatic in response to the sensor data and;
creating at least one learning agent to perform failure signature recognition with respect to the at least one unit of equipment; and
training the at least one learning agent by adjusting parameters of the at least one learning agent using machine learning, the training enabling the at least one learning agent to predict failures identified by the received failure information; and
storing the received sensor data in the associated memory along with metadata flagging one or more failure intervals and one or more normal intervals in the received sensor data.

Abstract
A system for performing failure signature recognition training for at least one unit of equipment. The system includes a memory and a processor coupled to the memory. The processor is configured by computer code to receive sensor data relating to the unit of equipment and to receive failure information relating to equipment failures. The processor is further configured to analyze the sensor data in view of the failure information in order to develop at least one learning agent for performing failure signature recognition with respect to the at least one unit of equipment.

15. A computer-implemented method of performing anomaly detection, the method comprising:
-
by one or more processors and associated memory; receiving;
(i) sensor data relating to at least one unit of equipment and (ii) failure information relating to one or more equipment failures;automatically determining one or more normal operating states of the at least one unit of equipment, the determining performed by analyzing the received sensor data over time periods different than periods of the one or more equipment failures; and training at least one anomaly agent to detect when a current operating state of the at least one unit of equipment is outside the determined one or more normal operating states, wherein the training is automatically performed by the one or more processors and includes; modeling the determined one or more normal operating states using a training model; monitoring for additional sensor data relating to the at least one unit of equipment; providing the additional sensor data to the training model, the training model determining an error associated with classifying the additional sensor data into an operating state of the determined one or more normal operating states; checking whether the determined error meets an anomaly threshold; and detecting an anomaly condition based upon results of the checking. - View Dependent Claims (16, 17, 18, 19, 20)
