Patent ID: 8725667

Claim:
A learning system, comprising: a processor; and a computer-readable storage medium storing computer executable components and communicatively coupled to the processor to facilitate operation of the computer executable components, the computer executable components comprising: a component configured to select a set of variables associated with data generated based on a first unit of equipment in a tool system and a second unit of equipment in the tool system, wherein the tool system is configured to produce an asset, and wherein the set of variables includes a reference variable and a set of influencing variables that influences the reference variable; an objective learning engine configured to learn autonomously a relationship among the reference variable and the set of influencing variables associated with the first unit of equipment and the second unit of equipment, wherein the objective learning engine is configured to remove an influencing variable from the set of influencing variables in response to a determination that a weight associated with the influencing variable is below a threshold value and a previous weight associated with the influencing variable is above the threshold value, and wherein the relationship among the reference variable and the set of influencing variables is autonomously adjusted in response to the removal of the influencing variable from the set of influencing variables in order to account for the removal of the influencing variable from the set of influencing variables; and a performance assessment component configured to compare a measured value of the reference variable and a predicted value of the reference variable based on the relationship among the reference variable and the set of influencing variables to determine a performance degradation or a performance mismatch of the first unit of equipment and the second unit of equipment.
