In this paper we present a method based on Hopfield neural networks which is a variant of a precedent semi-supervised approach that transfers protein functions from annotated to unannotated proteins. Unlike this approach, our method preserves the prior information and takes into account the imbalance between positive and negative examples. To obtain more reliable inferences, we use different evidence sources, and integrate them in a Functional Linkage Network (FLN). Preliminary results show the effectiveness of our approach.<\/jats:p>","DOI":"10.3233\/978-1-60750-692-8-52","type":"book-chapter","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T10:27:05Z","timestamp":1740133625000},"source":"Crossref","is-referenced-by-count":0,"title":["Learning functional linkage networks with a cost-sensitive approach"],"prefix":"10.3233","author":[{"family":"Bertoni Alberto","sequence":"additional","affiliation":[]},{"family":"Frasca Marco","sequence":"additional","affiliation":[]},{"family":"Grossi Giuliano","sequence":"additional","affiliation":[]},{"family":"Valentini Giorgio","sequence":"additional","affiliation":[]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","Neural Nets WIRN10"],"original-title":[],"deposited":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T11:29:22Z","timestamp":1740137362000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISSNISBN&issn=0922-6389&volume=226&spage=52"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-60750-692-8-52","relation":{},"ISSN":["0922-6389"],"issn-type":[{"value":"0922-6389","type":"print"}],"subject":[],"published":{"date-parts":[[2011]]}}}
