Classification: CPC G  Y | IPC G

Claim 16:
17. An apparatus for analyzing machine performance, comprising:
a processor;
memory communicatively coupled with the processor; and
instructions stored in the memory and executable by the processor to cause the apparatus to at least:
receive sensor data from a sensor associated with a machine;
determine an input matrix of sequential values based at least in part on the sensor data:
determine a penalty matrix of sequential penalty entries individually defining a penalty or no-penalty based at least in part on comparing a first one of the sequential values to a second one of the sequential values occurring prior to the first one of the sequential values;
determine sub-optimal operation of the machine based at least in part on the penalty entries over a period;
transmit an indication of the sub-optimal operation;
determine a replacement value representing a subset of the sensor data within a time interval;
determine an anomaly at the sensor by comparing the replacement value with a threshold; and
transmit an indication of the anomaly at the machine.
