PATTERN CONCEPTION METHOD AND DEVICE OF ARRAY GAS SENSOR

摘要

The present invention relates to a pattern recognition method and apparatus for an array gas sensor, which can improve the difficulty in signal processing and the discrimination speed due to the deviation of the sensor signal.;The present invention initializes category data so as to reduce the discrimination error by classifying the measurement and discriminating the untrained or unknown target gas into a separate category other than the existing category. If the probability is below the reference value, a new category is formed. If the probability is higher than the reference value, the input data is classified into the category having the highest probability, and the corresponding category including the classified data obtained above is obtained. If the coefficient of variation is above the threshold, a new category is formed.If the coefficient of variation is below the threshold, a new category is obtained. If the variance is larger than the standard variance, a new category is formed. In that 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.
