There's only what you can find in the javadoc comments.

I don't think we have anything that does coordinate ascent, but you can find other optimizers such as gradient ascent and conjugate gradient and implementations of gaussian priors. But the internals aren't all very well documented, so if you don't have a reasonable idea what you're doing, something else might be easier to work with....
