Signal interpretation engine
First Claim
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.

Abstract
A signal interpretation engine apparatus and method are disclosed in certain presently preferred embodiment as including a computer programmed to run a plurality of modules comprising a feature expansion module, a weight table module, a consolidation module, and a map generation module. The feature expansion module contains feature operators for operating on a signal to expand the signal to form a feature map of feature segments Each feature segment corresponds to a unique representation of the signal created by a feature operator operating on the signal across an epoch. An epoch corresponds to an event occurring within a time segment. The weight table module provides a weight table having weight elements Each weight element has a weight corresponding to a feature segment of the feature map. The consolidation module provides a superposition segment by combining the feature segments of the feature map corresponding to the epoch by forming an inner product of the feature map and the weight table. The consolidation module also applies aggregators to consolidate the inner products or superposition segments into a distribution function representing an attribute over a domain reflecting a selected weight table, aggregator, and event type, corresponding to each value of the attribute. The map generation module produces an interpretation map that reflects a preferred weight table and aggregator to be applied to the signal data to characterize the event.
