Claim 7:
8. A system for detecting an anomaly in an electronic component by analyzing an output of the electronic component or a device incorporating the electronic component during operation, the system comprising:
an input port configured to receive a data stream comprising an ordered sequence of data values generated by the electronic component, wherein the data stream is divided into a plurality of contiguous intervals; and
a controller configured to:
identify a new extracted data segment (EDS) of said data stream using an extraction protocol;
transform the new EDS to a clustering signature vector (CSV);
compare the CSV to a plurality of reference signature vectors (RSVs) using a similarity protocol to determine if the CSV is similar to any RSV of the plurality of RSVs;
when the CSV is similar to an RSV of the plurality of RSVs, store information associating the CSV with the similar RSV in an RSV database;
when the CSV is not similar to any RSV of the plurality of RSVs, create a new RSV for the CSV; and
predict that the electronic component will fail within a predetermined time period when the new RSV or the RSV with which the CSV is associated is a predictor RSV that occurs within the predetermined time period prior to failure of the electronic component as the electronic component ages; and
notify a user of the predicted failure of the electronic component,
wherein each RSV of the plurality of RSVs is characterized by a count function that depends on a number of CSVs that were found to be similar to that RSV in each of the plurality of contiguous intervals of the data stream, wherein the predictor RSV has a count function that increases as a function of position in the data stream.
