Therefore, it is very important to research on identifying the dangerous levels of various liquids. The paper establishes the [Formula: see text]-parameter database of tested samples under specific detection environment with free space method. In the actual detection, ultra-wide-band (UWB) centimeter wave is used to measure the [Formula: see text]-parameters of several detected liquids first. Then the fast independent component analysis (FastICA) algorithm is used for unmixing the mixed signal by Newton\u2019s iteration method and the negative entropy maximization search principle. The unmixed signal matches with the sample database adaptively, so the dangerous levels of the detected liquids are identified. Multiple experiments show that FastICA algorithm can reach a matching rate of 95% between water and 90[Formula: see text] gasoline or alcohol and 90[Formula: see text] gasoline, it also can reach a matching rate of around 73% between water and alcohol. This algorithm has a quick response and high reliability for identification of dangerous liquids. FastICA algorithm in this paper is applied for detecting the dangerous liquids for the first time, and it has high application value. <\/jats:p>","DOI":"10.1142\/s0218001419580035","type":"journal-article","created":{"date-parts":[[2018,7,4]],"date-time":"2018-07-04T04:22:11Z","timestamp":1530678131000},"page":"1958003","source":"Crossref","is-referenced-by-count":8,"title":["Research on Applications of FastICA Algorithm in the Detection of Dangerous Liquids"],"prefix":"10.1142","volume":"33","author":[{"given":"Dongmei","family":"Zhou","sequence":"first","affiliation":[{"name":"College of Information Science and Technology, Chengdu University of Technology, Chengdu 610059, P.
