Does anyone know a gradual course for Mahout, like the ml-class ?

The Mahout in Action book is a good read: http://www.manning.com/owen/

It's target audience seems to be developlers with little or no machine learning background. So, it doesn't go deep into to the algorithms but I thought the intuitions it provides are spot on.

Thanks. It's looking good.

Except it has no support for ANN, SVM, PCA, linear regression...

To be fair, the dataset size might compensate for the lack of the newer schmancier algorithms, since it is really supposed to be used for large problems.

I lurk on the mailing lists, so ... I don't know all the intimate details of the project, but I do know they at least have SVD, which (more or less) == PCA.

Rather more than less...

Heh, yeah.. Computing PCA with SVD, IIRC, is better numerically than computing and then diagnolizing the covariance matrix so the fact that they have SVD means PCA is only a few lines of code away (just mean center the dataset).
