METHOD AND DEVICE FOR AUTOMATIC PATTERN RECOGNITION
First Claim
1. A method for automatic pattern recognition in a sequence of electronic data by means of electronic data processing in a data processing system, where the sequence of electronic data is compared in an analysis with parameterized model data representing at least one pattern sequence in an analysis and where at least one pattern sequence will have been recognised, where the training data is processed to a set of feature vectors of equal length and the same content as the training data, from which the parameterised model data has been derived, by means of a dynamic time warping method, during the formation of the parameterized model data, if it has been established during the analysis that the model data enclosed by the parameterised model data allocated to at least one pattern sequence occurs with a level of similarity exceeding the similarity threshold.

Abstract
The invention relates to a method for the automatic pattern recognition in a sequence of electronic data by means of a electronic data processing in a data processing system, during which the sequence of electronic data is compared with parameterised model data representing at least one sample sequence, in an analysis and where at least one sample sequence is recognised if training data is processed to a set of characteristic vectors of the same length and with the same information content, from which the parameterised model data is derived, by means of a dynamic time warping method during the formation of the parameterised model data, if it has been established during the analysis that the model data enclosed by the parameterised model data, which are allocated to at least one sample sequence, occurs with a level of similarity exceeding the similarity threshold. In addition, the invention relates to a device for automatic pattern recognition in a sequence of electronic data by means of electronic data processing with a data processing system.

5. A device for automatic pattern recognition in a sequence of electronic data by means of electronic data processing, by a data processing system having the following characteristics:
-
pattern recognition means that is configured to compare the sequence of electronic data with parameterised data in an analysis and to recognise at least one pattern sequence, if it has been established during the analysis that the model data enclosed by the parameterised model data allocated to at least one pattern sequence occurs with a level of similarity exceeding the similarity threshold and model data creation means configure to create the parameterised model data using training data and to process the training data to a set of feature vectors of the same length and with the same information content as the training data from which the parameterised model data has been derived by means of a dynamic time warping method and provision means configured to provide electronically assessable identification information by recognising at least one pattern sequence for an output.
