a) Implemented code exists in trunk for the ones that need to be retained, so you can retain the Wiki pages for those. b) The ones that have been deprecated, please purge the corresponding Wiki pages. The release notes for 0.9 will capture the reasons for the deprecation.

I believe we should remove the team Deprecated and either: 1) Use the term draft to distinguish from fully supported or .. 2) . to commit the algorithms included in the trunk will be fully supported.

See inline. The code for the deprecated algos has already been purged from trunk, its only the Wiki that needs cleaning up.

It could be because:- a) they have been replaced by better performant alternatives b) lack of usage c) lack of support Please delete from wiki all algorithms that have been marked deprecated (the code for most of them has already been removed from trunk).

What is the reason? Is it because they are less efficient compared to the supported ones or is it due to lack of resources working on them to be supported with Mahout? Thanks Sotiris
