ABSTRACT:
A method and apparatus for determining the possibility of pattern recognition of time series signal independent of a pattern recognition ratio is provided. The method for determining the possibility of pattern recognition of time series signal includes extracting a time forward feature and a time reversed feature from an input signal having a time series pattern, generating time forward alignment and time reversed alignment by using the time forward feature and the time reversed feature, comparing the time forward alignment with the time reversed alignment to compute a likelihood of pattern recognition, and determining that the input signal can be recognized if the likelihood is larger than a predetermined threshold value. The possibility of the pattern recognition of the whole system can be determined, independent of the pattern recognition capability of each of the pattern recognition models, by extracting the patterns from the time series signal by using the plurality of the pattern recognition models and then obtaining the likelihood between the patterns to compare the likelihood with the threshold value. In addition, the pattern recognition can be performed in the non-limited environment.
