However, typical optical methods assume spherical particles, which most ingested particles are not. We present a novel application of machine learning models that takes scattering and extinction observations as inputs and estimates non-spherical particle shape (via aspect ratio) and size. The overall method of multiple classification and regression layers, as well as the results from three test cases using simulated inputs are presented.","PeriodicalId":220244,"journal":{"name":"2020 IEEE Research and Applications of Photonics in Defense Conference (RAPID)","volume":"389 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115853335","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}
