Description
Summary:Two Component Correction methods for drift compensation in chemical sensor arrays have been evaluated in terms of classification accuracy. A well established linear method based on computing Principal Components of the reference gas is applied to a dataset, where three different reference gases are examined. The proposed method in this contribution is based on computing a Common Component Principal Analysis, which discovers a variance direction followed by all gasses in feature space. This new method-employing no reference gas-has shown the same performance as the traditional approach with the best fitted reference gas.
