PATTERN CONCEPTION METHOD AND DEVICE OF ARRAY GAS SENSOR

摘要

The present invention relates to a pattern recognition method and apparatus of a gas sensor array in order to improve the difficulties and on the signal processing speed is determined by the deviation of the sensor signal.; The present invention initializes the category data to allow to reduce the determined error by classifying as a separate category of non-existing category for not learning, at the same time as measurements to allow for discrimination, or for the gas to the unknown, to read the input signals in each category seeking a probability included in, and the probability that form both the reference value or less is a new category, and classify input data into categories with which the probability of any of highest probability is more than the reference value, this category including the classification data obtained in the asking for the variation coefficient, the coefficient of variation to form a new category is above the reference value, seeking the distribution of the variation coefficient of the reference value or less if the corresponding category, and distributed to form a large, new category than the standard dispersion, if the variance is less than the standard deviation in this category The flow, and it will determine which improves the speed determined by the reformation display data after the probability that the different categories of all the data, to reduce the determined error.
