This problem is generally faced by optimizing a weighted combination of functions measuring the quality of co-clustering over each pair of domains, where weights are chosen based on the supposed reliability/relevance of their correlation.\nHowever, little knowledge is likely to be available in practice in order to set these weights in a definite and precise manner. And, more importantly, it might even be conceptually unclear whether to prefer a weighing scheme over others, in those cases where functions encode contrasting goals so that improving the quality for a pair of domains leads to a deterioration for other pairs.\nThe aim of this paper is precisely to shed light on the impact of weighting schemes on techniques based on linear combinations of pairwise objective functions, and to define an approach that overcomes the above problems by looking for an agreement - intuitively, a kind of compromise\u00E2\u0080\u0094among the various domains, thereby getting rid of the need to define an appropriate weighting scheme. Two algorithms performing co-clustering on star-structured\u0080 domains, based on linear combinations and on agreements, respectively, have been designed within an information theoretic framework.\nResults from a thorough experimentation, on both synthetic and real data, are discussed, in order to assess the effectiveness of the approaches and to get more insight into their actual behavior."@en . @prefix ns12: . prodotto:ID14579 pubblicazioni:editore ns12:ID322 ; prodottidellaricerca:prodottoDi modulo:ID2272 , istituto:CDS018 ; pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA8261 . @prefix parolechiave: . prodotto:ID14579 parolechiave:insiemeDiParoleChiave . ns12:ID322 pubblicazioni:editoreDi prodotto:ID14579 . ns11:ID510201 pubblicazioni:rivistaDi prodotto:ID14579 . parolechiave:insiemeDiParoleChiaveDi prodotto:ID14579 .
