摘要
Statistical learning and recognition methods were used to extract the characteristics of size series measurements of cocoon filaments that are non-stationary in terms of mean and auto-covariance,by using the time varying parameter auto-regressive(TVPAR)model.After the system was taught to recognize the size data,the system correctly recognized the size of series of cocoon filaments as much as 96.95%of the time for a single series and 98.72%of the time for the mean of two series.The correct recognition rate was higher after suitable filtering.The theory and method can be used to analyze other types of non-stationary finite length time series.
