Signal interpretation engine
First Claim
1. An apparatus comprising:
- a feature expansion module programmed to use at least one feature operator to expand a signal segment, corresponding to an event in at least one of frequency space and time space to generate a plurality of feature segments corresponding to the signal segment;
a weighting module programmed to generate a weight table comprising a plurality of weights; and
a consolidation module programmed to form an inner product between the plurality of feature segments and the weight table to generate a weighted plurality of feature segments.

Abstract
A signal interpretation engine apparatus and method are disclosed as including a computer programmed to run 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 from the signal across an epoch. An epoch corresponds to an event within a time segment. A consolidation module 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.

9. An apparatus comprising:
-
a feature expansion module programmed to use at least one feature operator to expand a signal segment, corresponding to an event, in at least one of frequency space and time space to generate a plurality of freature segments corresponding to the signal segment; a weighting module programmed to generate a weight table comprising a plurality of weights; a consolidation module programmed to form an inner product between the plurality of feature segments and the weight table to generate a weighted plurality of feature segments, superimpose the weighted plurality of feature segments to form a feature, and use an aggregation procedure to aggregate the feature to a numerical value; and a map-generation module programmed to iteratively select the at least one feature operator used by the feature expansion module, the values of the plurality of weights forming the weight table, and the aggregation procedure used to aggregate the feature to a numerical value to identify an interpretation map comprising a combination of the at least one feature operator, weight table, and aggregation procedure that produces a feature displaying a pattern characteristic of the event.
