英文摘要：

To simplify the complex process of designing features by hands,to make the features more general,and to improve the classification accuracy of gases,agas recognition method based deep learning was proposed that could extract self-adaption features.Two methods based UCI machine learning database were compared respectively in the experiments.One was a two-level structure of deep neural network-stacked denoising autoencoders,and the other was a kind of shallow machine learning algorithms used in gas qualiative recognition.Results show that extracting features automatically with deep learning is a simpler and more universal way in gas recognition.The method not only improves the classification accuracy of gases,but also reduces the complexity of the process using traditional shallow machine learning algorithms.
