1. A failure sign diagnosis device for performing failure sign diagnosis on an instrument using sensor data obtained from the instrument with the use of a plurality of sensors, comprising:
processed sensor data generation means for generating processed sensor data by performing processing on the sensor data;
preprocessing condition generation means for generating processing conditions for the processing that increases correlation coefficients between the plurality of sensors as preprocessing conditions;
failure sign diagnosis model update means for updating a failure sign diagnosis model of the instrument on the basis of the preprocessing conditions;
diagnosis processing means for performing failure sign diagnosis on the instrument using the failure sign diagnosis model; and
sensor combination generation means for generating sensor combinations on the basis of correlation coefficients between the sensor data and the processed sensor data,
wherein the preprocessing condition generation means generates the preprocessing condition for each of the sensor combinations generated by the sensor combination generation means.
