Embodiment Construction
[0079] Aiming at the problem that the drift of the gas sensor of the electronic nose affects the accuracy of gas recognition, the present invention provides an electronic nose heterogeneous data recognition method based on target domain migration limit learning, and analyzes and solves the problem from the perspective of a machine learning machine , a concept based on target domain migration limit learning is proposed, with the help of a small number of electronic noses that collect the gas sensor array sensing data matrix when there is no drift and the labeled and unlabeled gas sensor array sensing data collected after drift Data matrix, construct source domain data set, target domain data set and test domain data set respectively, to carry out extreme learning of target domain domain migration to obtain a robust recognition classifier, which can improve the recognition classifier in electronic nose Tolerance performance of gas recognition after drifting, when the recognition ...
