In order to achieve this objective simpler and faster, DWDM network reconfiguration procedures are needed. A key problem that is intrinsically related to network reconfiguration is that of the quality of transmission assessment. Thus, in this contribution a Machine Learning (ML) based method for an assessment of the quality of transmission is proposed. The proposed ML methods use a database, which was created only on the basis of information that is available to a DWDM network operator via the DWDM network control plane. Several types of ML classifiers are proposed and their performance is tested and compared for two real DWDM network topologies. The results obtained are promising and motivate further research.<\/jats:p>","DOI":"10.3390\/e23010007","type":"journal-article","created":{"date-parts":[[2020,12,22]],"date-time":"2020-12-22T12:42:28Z","timestamp":1608640948000},"page":"7","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Machine Learning Algorithms for Prediction of the Quality of Transmission in Optical Networks"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6647-5189","authenticated-orcid":false,"given":"Stanis\u0142aw","family":"Kozdrowski","sequence":"first","affiliation":[{"name":"Computer Science Institute, Warsaw University of Technology, Nowowiejska 15\/19, 00-665 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8049-7410","authenticated-orcid":false,"given":"Pawe\u0142","family":"Cichosz","sequence":"additional","affiliation":[{"name":"Computer Science Institute, Warsaw University of Technology, Nowowiejska 15\/19, 00-665 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Piotr","family":"Paziewski","sequence":"additional","affiliation":[{"name":"Computer Science Institute, Warsaw University of Technology, Nowowiejska 15\/19, 00-665 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4588-6741","authenticated-orcid":false,"given":"S\u0142awomir","family":"Sujecki","sequence":"additional","affiliation":[{"name":"Telecommunications and Teleinformatics Department, Wroclaw University of Science and Technology, Wyb.
