The device contains custom made metal oxide sensors that are controlled by a Teensy 3.6 microcontroller. The gas classification experiment was performed with an automatic test rig on four compounds, acetone, ammonia, ethyl acetate and synthetic urine; at five concentration levels and three humidity levels. The collected data were processed employing three classifier methods, k-nearest neighbour (KNN), a shallow neural network (MLP) and a convolutional neural network (CNN). The overall classification accuracies of these three models are 93.5%, 92.6% and 95.4%, respectively. More importantly, both KNN and CNN have 100% success rate in urine classification, and only one misclassification of synthetic urine occurred with the shallow neural network.","PeriodicalId":427373,"journal":{"name":"2022 IEEE International Symposium on Olfaction and Electronic Nose (ISOEN)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126210193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, high-frequency oscillations (HFO, 130–180 Hz) has also attracted widespread attention, which is a novel neuronal oscillation with a frequency range close to high gamma (HG) oscillations. Both of two oscillations are distinctly regulated by theta rhythm in the hippocampus. In order to understand their mediation mechanisms in the OB, we testes whether HG and HFOs, and even their coupling with theta rhythm are modified by odor stimulation in freely-moving rats by combining electrophysiological and cross-frequency coupling analysis approaches. The obtained results indicate that HG and HFOs and their theta phase-locked coupling were differently modified by odor stimulation, suggesting that these oscillations and their interactions with theta oscillations may play roles in olfactory network activity. This could pave the way to further understand the underlying mechanisms of oscillations in olfactory bulb neurons towards odor sensation.","PeriodicalId":427373,"journal":{"name":"2022 IEEE International Symposium on Olfaction and Electronic Nose (ISOEN)","volume":"50 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133235418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
