Abstract
An original model is stored in a data storage device. The original model describes or represents the operation of an industrial machine. A stream of data is received from the industrial machine at a control circuit. At the control circuit, the streaming data is mapped to the original model of the industrial machine. Features or labels in the stream of data related to the industrial machine are determined, and a predetermined event in the stream of data that is related to the features or labels is detected. Upon detection of the occurrence of the predetermined event, a modified or fitted model is derived, and predictions about performance of the industrial machine are derived utilizing the modified or fitted model.
Claims18
A method for tuning a model that describes behavior of an industrial machine, the method comprising:
- storing an original model in a data storage device, the original model describing the operation of an industrial machine;
- receiving a stream of data from the industrial machine at a control circuit;
- at the control circuit:
- mapping the streaming data to the model of the industrial machine;
- determining features or labels in the stream of data related to the industrial machine;
- detecting a predetermined event in the stream of data that is related to the features or labels;
- upon detection of the occurrence of the predetermined event, deriving a modified model from the original model;
- and
- deriving predictions about performance of the industrial machine utilizing the modified model.
A system of tuning a model that describes behavior of an industrial machine, the system comprising:
- a data storage device that is configured to store an original model that describes the operation of an industrial machine;
- a transceiver circuit that receives a stream of data from the industrial machine;
- a control circuit that is coupled to the data storage device and the transceiver circuit, the control circuit being configured to:
- map the streaming data to the original model of the industrial machine;
- determine features or labels in the stream of data related to the industrial machine;
- detect a predetermined event in the stream of data that is related to the features or labels;
- upon detection of the occurrence of the predetermined event, derive a modified model from the original model;
- derive predictions about performance of the industrial machine utilizing the modified model.
