Hi Yoonmin, we removed a bunch of algorithms either because they were rarely used or not actively maintained anymore. IIRC the first thing was true for PFG. --sebastian On 01/20/2014 03:42 AM, Yoonmin Nam wrote: Hello, everyone! Is there anyone know about the reason why PFG is deprecated

that's a bit weird though. Association mining is still a pretty popular technique. (our scientists use it, albeit not in exact FPGrowth form) On Mon, Jan 20, 2014 at 3:15 PM, Sebastian Schelter s...@apache.org wrote: Hi Yoonmin, we removed a bunch of algorithms either because they were

I was asked this question too and I had no clear answer. May be it wasn't right to remove FP from the codebase. Not having this may well be one another reason for users to look at options other than Mahout. Given the issues that Frank's reported with Streaming KMeans (and I am seeing them too)

it seems more like it is not supported. I'd port it into spark counterpart and make sure there's a support (i.e. a person to go after when it breaks :) On Mon, Jan 20, 2014 at 3:44 PM, Suneel Marthi suneel_mar...@yahoo.comwrote: I was asked this question too and I had no clear answer. May be

May I ask what is the qualification to be the maintainer? I have read this part of code, and would like to have a try. Best Regards, Qinghao 2014/1/20 Ted Dunning ted.dunn...@gmail.com On Mon, Jan 20, 2014 at 5:44 PM, Suneel Marthi suneel_mar...@yahoo.com wrote: I was asked this question

(1) diligently answer inqueries about method use and theoretical foundation on the user list (2) fix arising issues related to that stuff, diligently as well. when (1) and (2) stops happening, the method gets axed in a year or couple releases (which what pretty much happend this time i think).

Hello, everyone! Is there anyone know about the reason why PFG is deprecated in Mahout? I knew that new algorithm (BIGFIM) will be implemented as a substitution of old PFG algorithm for parallel frequent pattern mining. Please let me know if you knew the reason. Thanks!
