Mahout beginner's how-to

[Petr Cvengros <pe...@volny.cz>]

Hello,

I've written a short beginner's how-to on building Mahout and creating
a simple recommender:
http://code.google.com/p/unresyst/wiki/CreateMahoutRecommender

I don't think anyone in this mailing list will find it useful, but at
least you can check it and potentially direct there the newbies asking
questions.

Have a nice day!

Petr

[Sean Owen <sr...@gmail.com>]

It sounds like most questions concern setup of a project. I agree it's
not trivial to understand how to use Maven, though that's a question
of learning Maven rather than Mahout. Likewise for Eclipse, or for
IntelliJ, or for integrating this into an Ant project, or setting up a
servlet container. There are a hundred setups you could document. All
are useful -- just that it's a load of work to write and maintain!

There is generally much more work that could be done than there is
active contribution to the project. So this sort of activity in the
wiki or project is most welcome as it's not going to get done
otherwise probably; the code itself still needs plenty of work let
alone documentation, which I don't think anyone is meaningfully
working on at the moment. Parts of the implementation have gone a bit
stale already and so are in ways inconsistent with other parts, which
contributes to the getting-started problem.

The scope of the project is ambitious, and it is hard to make this
stuff a simple API as the underlying mechanics are complex enough, and
the use cases so varied, that a really complete packaging and
treatment of it even in the code would be a project five times larger.
Beyond basic usage, you need to be at HEAD in Subversion and in the
source code to understand and work with it anyway. This is just going
to be hard to gently introduce no matter what..

I think it gets better over time as things slowly mature and ways of
doing things on Hadoop get more standard. In the short term it's only
going to improve through contributions so these are all very welcome.
Putting this into the project wiki would be the most ideal thing.

Yes. I recently bought the book, and it's worth every penny.

I've been experimenting with Mahout since last year, but it took quite
a bit of messing around before getting to the stage where I knew it
was something that I wanted a book about. Having a bit more gentle
intro material free online would only complement the book, and help
people realise they'd benefit from it.

My learning experience was fairly positive so far. I first followed
the Taste demo and happily swapped out the data file for one of my
own, which gave me a simple demo recommender without writing a line of
code. That simple exercise was very reassuring.

After that, the trail scattered in various directions and I felt
relatively lost. Should I talk the ant build file from the demo .zip
at http://www.ibm.com/developerworks/java/library/j-mahout/ and
explore from there? Or build on top of Maven? Or on the commandline
since there seem to be a lot of commandline utilities. And that
familiar "I guess I should try using Eclipse again" feeling. If I care
about the Hadoop side, how does that affect my choices? if I want to
code in another language should I build REST services with the HTTP
service machinery that comes with Taste, or is that just for demos,
just for recommenders? I doubt there are 'right' answers to all of
these, but I felt as if stood at a crossroads with interesting arrows
pointing in every direction. So buying the book gives a bit of
structure to all this. While not a natural user of Eclipse, I got set
up and worked through the examples (copypaste from pdf mostly, a bit
frustrating but forced me to really read the code). This helped hugely
in getting from "I'm pretty sure I heard that Mahout does X" to having
running code on my machine that actually does it...

Hi Petr and all,

This is very helpful one for beginner like me and thank you very much for
sharing this information. Few months back me too found [1] and worked a
maven project with that. I think that project will do some small help for
somebody who is trying to understand the basics and see what happens. So I
created a google-code project and added what I had in my machine. It can be
found here [2].

One more request from Mahout experts is if you can add some more resources
like academic papers and etc. to the site from the basic level it will be a
real help for all who interested in Mahout.

Yeah, I believe the book is great. Its only problem is that it isn't
free and the first free chapter doesn't give much details on setting
Mahout up. People who would like to experiment a bit with an open
source library usually aren't willing to buy a $30 book. Anyway, I
think at least the introductory documentation should be freely
available.

Hey Petr, 

I think a lot of people do not realize this great source of info for learning Mahout:
http://www.manning.com/owen/

This book is fantastic.  Maybe you can place a link in your sources.

I don't think there's enough introductory stuff in the web Mahout
docs, otherwise I wouldn't have written the how-to, as writing
how-to's isn't my primary hobby.  Especially creating and setting up
the Maven project and running a simple recommender on dummy data
wasn't covered in any page I've seen. Maybe it's somewhere, but I
didn't find it and obviously nor did most of the others.

I think for people who know some Java but have no experience with
Mahout and Maven (as me) it's quite hard to get Mahout work for them.
At least I have spent quite a lot of time realizing the stuff
described in the how-to.

As Sebastian proposed, I'm thinking about merging some of the how-to
to the Mahout wiki - at least the mentioned parts.

Re: Mahout beginner's how-to

[Sean Owen <sr...@gmail.com>]

I think any new writeups are welcome. This can go on the Mahout wiki
too. Though there is also a fairly complete walkthrough of this same
code on the Mahout wiki. I wonder if people are finding that.
Mahout in Action covers all of this in a great deal of detail too.

Hi Petr,

we find it very useful! Actually a lot of Mahout users are just in this
