1. An apparatus for providing an interpretation corresponding to a signal, the apparatus comprising a computer programmed to run a plurality of modules comprising:

  • a feature expansion module containing feature operators operating on a signal, expanding the signal to form a plurality of feature segments, each feature segment corresponding to a unique representation of the signal across an epoch corresponding to an event occurring within a time segment, the event having a type;

    a consolidation module for forming inner products between the plurality of feature segments and a weight table comprising weight elements, and for applying aggregators to consolidate the inner products into a distribution function representing an attribute over a domain, the domain having one or more values;

    a map generation module for producing an interpretation map reflecting a preferred weight table and aggregator to be applied to the signal data to characterize the event.
