Title:
DEVICE AND METHOD FOR GENERATING COMBINATION FEATURE VECTOR FOR GAS CLASSIFICATION
Document Type and Number:
WIPO Patent Application WO/2017/104911
Kind Code:
A1
Abstract:
Presented are a device and a method for generating a combination feature vector for gas classification, the device and the method enabling a combination feature to be generated by: extracting an entire area feature by using an entire area sample in an overall measurement section; extracting a regional feature by using a regional sample of a stabilization section, an exposure section, and a purge section; and extracting an entire area feature and a regional feature having a large amount of discernment information. The presented device for generating a combination feature vector for gas classification comprises: a gas measurement unit having a sensor array, which has a plurality of channels and a plurality of sections, and measuring a reaction by means of gas introduced into a chamber so as to generate gas data; a determination feature extraction unit for extracting a determination feature on the basis of the gas data generated by the gas measurement unit; and a combination feature vector generation unit for generating a combination feature vector on the basis of the gas data generated by the gas measurement unit and the determination feature extracted by the determination feature extraction unit.
