Re: How to use kmeans clustering algorithm of Mahout

[Paritosh Ranjan]

I think you will need these two commands ( in the same order ) :

seqdirectory : Generate sequence files (of Text) from a directory
seq2sparse: Sparse Vector generation from Text sequence files

I think I didn't explain clear enough and sorry for that.

The example showed before is a part of my data.

Each line is a user profile, for example, the first row is the features of
a user. And I want to apply k-means to this data.

I need to create a file saves all users profile as sparse vector and put
them in mahout k-means algorithm, how can I do that?

  Thanks for your advice!

I could not understand the question correctly, can you explain more?

Aloha!

    I am new to hadoop and mahout, but I have set up the hadoop cluster.

    I am working on a clustering task lately. I think I could not make it
quickly because I don't know too much about how to deal with massive data (
my data contains 1400000 user and 50000 features..plus that is sparse ).

    Could you tell me how deal with that? A slice of data is here:

167555,152622,162252,79481,**66540,41942,75500,167898,**
61923,182083,180681,181135,**174449,166439,167307,174126,**87800,2826,
     98660,158620,33900,

38201,112101,4048,1716,167599,**140883,158250,175399,

     example above contains 4 user's data and each number is nominal
(denoting that is a kind of behavior of user, e.s, user 2 has
"98660","158620","33900" )

     Please tell me how to work on that or which documents should I read..


     Thx!
