Executive Summary  Analyzing 0-1 matrices is one of the main
themes in data mining. Techniques such as clustering or mixture
modelling, matrix decomposition techniques such as PCA, ICA, and
NMR, and Bayesian all aim to give an answer to the informal
question: "Where does the matrix come from?" These approaches
aim at describing a probabilistic generative model that
describes the observed matrix well. This paper considers yet
another way of answering the question "Where does a 0{1 matrix M
come from?" In the model, the matrix M of size n ? m is
considered to arise from initiators, certain few entries that
are initially 1.    • Format: PDF   • Size: 284.2 KB
