Title: Infrared spectrum identifying method
Inventor: TANABE KAZUTOSHI
IPC: G01N21/35
Filed: 1990-03-13
Abstract: PURPOSE:To shorten the processing time by using a neural network when infrared spectrum data on an unknown compound and a standard sample are compared to decide a score. CONSTITUTION:Unknown data are narrowed down to 1/n possibility in the initial stage of the neural network and further narrowed down to 1/m possibility in the 2nd stage of the neural network, and scores of individual compounds are outputted finally. Data for the learning of the neural network are generated by using the infrared spectrum data on the standard sample. Then 10 data are selected among those data at random and the neural network learns them. Then the network which already learns the data recognizes the patterns of the remaining data to extract patterns whose output values are larger than a constant value and learns them again. In this process, similar patterns are gathered in one category and this process is repeated until all compounds are classified by 10 categories finally. Learning is performed with the infrared spectrum data on the standard sample finally to complete the identification.
