Abstract:
The analysis of genomic data from DNA microarray can produce a valuable
information on the biological relevance of genes and correlations among them.
In the last few years some biclustering techniques have been proposed and
applied to this analysis. Biclustering is an un-supervised learning task aimed
to find clusters of samples possessing similar characteristics together with
features creating these similarities. Starting from the seminal paper by Cheng
and Church published in 2000 [1], many biclustering techniques have been
proposed for bioinformatic data analysis [2]. Biclustering is especially
useful when applied to the analysis of DNA microarray data since it can tackle
the important problem of identifying genes with similar behavior with respect
to different conditions. Some biological tasks where biclustering can be
successfully applied are: (1) Identification of co-regulated genes and/or
specific regulation processes; (2) Gene functional annotation; (3) Sample
and/or tissue classification. In this tutorial we will focus on the fuzzy model
of biclustering as it is very promising from both a computational and a
representation point of view [4,5,6,7]. This model allows finding multiple
solutions (thus avoiding problems such as random interference [7]) with
significant speed. Moreover, some techniques, based on the fuzzy-possibilistic
approach to clustering, can find very large and homogeneous biclusters, as
shown by experimental results. In the tutorial we will present also an
experimental assessment of fuzzy biclustering algorithms, using some
computationally parsimonious stability indexes [8] .
