Method and apparatus for automatically constructing application signatures

A system for generating a final signature for an application, comprising:

• means for deriving an initial application signature using a first training data set;
• means for testing said initial application signature with a single validation data set;
• means for obtaining at least one cost minimizing parameter;
• means for creating a plurality of trained application signatures using both said at least one cost minimizing parameter and a plurality of preclassified training data sets;
• means for testing each of said plurality of trained application signatures using a plurality of preclassified validation data sets;
• and
• means for determining said final signature from said plurality of trained application signatures.

A computer readable storage medium having stored thereon instruction that, when executed by a processor, causing the processor to perform a method for generating a final signature using machine learning, comprising:

• deriving an initial application signature using a first training data set;
• testing said initial application signature with a single validation data set;
• obtaining at least one cost minimizing parameter;
• creating a plurality of trained application signatures using both said at least one cost minimizing parameter and a plurality of preclassified training data sets;
• testing each of said plurality of trained application signatures using a plurality of preclassified validation data sets;
• and
• determining said final signature from said plurality of trained application signatures.
