Iterative analysis of microarray data

In the past decade, technologies have been developed that enable researchers to quantify the levels of specific DNA transcripts present in cultures and tissues. While the signal-to-noise ratios of these technologies has consistently improved over the years, the signals provide only an observable projection of hidden, complex underlying processes. A variety of interesting information processing problems aimed at uncovering these hidden processes have emerged, and in this paper we survey some of the problems being studied in our group.
