A new study on Machine Learning is now available. According to news originating from Zografos, Greece, by NewsRx correspondents, research stated, “We developed a cluster-detection method based on the code DBSCAN to identify star clusters in the central region of the Small Magellanic Cloud (SMC). Two approaches were used to determine the values of the free parameters of DBSCAN.” Financial support for this research came from European Space Agency (ESA) space mission Gaia. Our news journalists obtained a quote from the research from the National and Kapodistrian University of Athens, “They agree well with each other and can be used in the fields that are studied without any a priori knowledge of clustering, characteristic scales, or background density. We validated the success of the DBSCAN cluster-detection method on recent cluster catalogues after introducing a cluster-classification scheme based on three diagnostics that relie on colour-magnitude diagrams and growth curves. We used data from the Magellan Telescope at the Las Campanas Observatory in Chile and from Gaia Data Release 3. As a byproduct of the validation process, we revisited objects that were classified as clusters in recent compilations. We found that 40% fail all diagnostics and most probably are not clusters.” According to the news editors, the research concluded: “DBSCAN was very successful in recovering actual clusters with high precision and recall.”
