A fundamental problem in developmental systems biology is to understand driving forces behind organ formation. In this talk, we use 400+ high-throughput TF images from fruitfly embryoic stage 4-6 to relate these TFs in order to shed light into the TF cascades that trigger organ formation processes. We borrow sparse coding ideas from computational neuroscience/computer vision to decompose the images into principal patterns that capture the locations and shapes of  group TFs and compare with costly human annotations.
