Subject: Plaid models for microarray data
  A new model for analyzing gene expression
data is available.  The plaid model clusters
genes, but:

   *  genes can belong to more than one cluster
   *  gene clusters can be defined by some but
      not necessarily all, of the samples
   *  samples cluster genes, genes cluster samples,
      in the same model

  The technical report and some slides are available
at

http://www.stanford.edu/~owen/plaid

  The same model with two-way overlapping clusters
might be applicable to some problems in information
retrieval and recommender systems.

  Plaid was developed by Stanford statisticians
Laura Lazzeroni and Art Owen.
