ROBUST DISTANCE MEASURES FOR ON-LINE MONITORING
First Claim
1. A method for making predictions based on a non-parametric empirical model used in monitoring a system, the method comprising:
- receiving a query vector of monitored parameters for the non-parametric empirical model characterizing the system;
determining robust distances between the query vector and each of a set predetermined historical vectors for the non-parametric empirical model based on an implementation of an elemental kernel function;
determining weights for the monitored parameters based on the robust distances;
combining the weights with the predetermined historical vectors to make predictions for the system.

Abstract
An apparatus and associated method are utilized for monitoring an operation of a system characterized by operational parameters. A non-parametric empirical model generates estimates of parameter values in response to receiving a query vector of monitored parameters for a model characterizing the system. A distance estimation engine (a) determines robust distances between the query vector and each of a set of predetermined historical vectors for the non-parametric empirical model based on an implementation of an elemental kernel function; (b) determines weights for the monitored parameters based on the robust distances; and (c) combining the weights with the predetermined historical vectors to make predictions for the system.
