Some templates learned from non-aligned training images
Reproducibility page for Statistical Science paper
This is a review paper we were invited to write for a special issue on
the EM algorithm for the journal of Statistical Science. The paper uses more
mathematically explicit notation, and introduces the model and leraning by
gradually developing the shared matching pursuit algorithm. The EM formulation
is particularly useful for unsupervised learning. The webpage
was last updated in October 2010.
Reproducibility page for ICCV paper
This is our first paper on this topic. The appendix shows that the linear additive
model with Gaussian white noise residual is a special case of the density
substitution scheme (which itself is a special case of maximum entropy tilting)
for putting probability distribution on image intensities. The webpage was last updated in Feb 2008.
