Algorithms for Molecular Biology 1–13 (2006) Multi-Objective Clustering Ensemble with Prior Knowledge Katti Faceli1 , Andr´e C. P. L. F. de Carvalho1, and Marc´ılio C. P. br Abstract. In this paper, we introduce an approach to integrate prior knowledge in cluster analysis, which is diﬀerent from the existing ones for semi-supervised clustering methods. In order to aid the discovery of alternative structures present in the data, we consider the knowledge of some existing complete classiﬁcation of such data.
We test the performance of both algorithms on a set of planted motif instances. Preliminary experimental results show a promising superior performance of the algorithm encoding the candidate motif over the more standard position based scheme. 1 Introduction The Motif Finding Problem can be deﬁned as to ﬁnd short conserved sites in DNA sequences without knowing, a priori, the length nor the bases that compose them. Until now, algorithms have been developed to identify motifs that appear in several sequences.
They should also Multi-Objective Clustering Ensemble with Prior Knowledge 39 complement each other. For the completely unsupervised case, we have used the same measures employed in : overall deviation and connectivity. The overall deviation of a partition measures the overall summed distances between objects and their corresponding cluster center. This measure is strongly biased towards spherically shaped clusters and improves with the increase in the number of clusters. The connectivity reﬂects how often neighboring objects have been placed in the same cluster.
