Abstract: A method of recognizing a pattern in a signal is provided. The method includes receiving, by a processor and at an input, the signal comprising data; converting, by the processor and based on a plurality of features, the data from the signal into a collection of features; identifying, by the processor, one or more feature-to-feature transitions between features in the collection of features; plotting, by the processor, a directed graph of each of the feature-to-feature transitions, wherein each unique feature in the collection of features is represented by a single vertex and each feature-to-feature transition is represented by a directed edge between two vertices weighted by a corresponding number of each of the feature-to-feature transitions; and detecting, by the processor, a pattern in the data by comparing the weight of each of the feature-to-feature transitions in the directed graph to a user-defined threshold.
