Neural Network and Restricted Boltzman Machine in Mahout
Hi,
I am interested using Neural Network type of tools to do classification in
Mahout. I wonder if these methods are finished in Mahout 0.8. On Mahout
website, it still says open.
Thanks,
Ying

There is a semi-done RBM patch in JIRA that was started by a GSOC student a few years back. He made some progress and then abandoned. You might look there. I think there is always interest in good, well tested patches, but we are mostly focused on cleaning things up right now trying to get out 0.8.

You mis-use map-reduce is how you do it.
Start a bunch of cores and nominate some of them to be parameter stores and
many to be workers. Pretend you are running either a map-only task or lots
of reducers on an identity mapper.

How do you do 'asynchronous sgd" with hadoop? (I guess referring to the
spark discussion in a different thread)
In any case there are ways to get similar performance without having to use
that many cores.
See our paper 'affinity weighted embedding"

Ray,
I'm now working with Ted on streaming k-means clustering for my senior
project. I come from a software engineering background.
Once I'm done, I'd be happy to help (coding?) and see what would be needed
and learn more about the whole deep learning thing (my experience with
neural networks is just from an intro ML class).
In any case, if you need any Java help, feel free to ask. I'll in turn want
to know more about the math. ;)

Ted,
It's very interesting that you put it this way, "a replication of this
architecture". It's really compelling to pursue this. I'm working
through one of the deep learning papers from the quoted link now to get
an idea of what it would take to make it happen. For me right now
though, it seems like a little much.
I mean, as a mathematician I find the mathematics being used in Mahout
refreshing. Some absolutely beautiful applications. Real life math on
the hoof. On the other hand, as a relative newcomer to Java, I'm still
coming up to speed.
I'll focus for now on contributing to documentation, possibly some
patches. See how the contribution process works, gain a little
confidence there first. (I do have a background in neural networks.)

Yeah.... we have had little pull on these techniques beyond the simplest
case of logistic regression.
Would you guys be willing to sign up for maintaining the code that might
result?
The thing that might move the needle would be a replication of this
architecture:

If you're really insistent on a hidden layer, Paul Mineiro has been
blogging about a NN implementation on top of VW that sounds interesting:

Vowpal Wabbit comes to mind for logistic regression on a data set like this.
Mahout's SGD should work as well.
Other SGD systems would work as well.

It's a sparse dataset. In average each record has about 200 independent
variables.

Is this a dense dataset or sparse? What is the average sparsity if so.

Re: Fwd: Neural Network and Restricted Boltzman Machine in Mahout

I asked years ago whether someone would be interested in starting
implementations of neural network algorithms in mahout, but apparently t here
was no big interest / priority and feedback that time. Maybe this has changed,
as Neural Networks yet again become more popular.

Can anyone in dev/commits shed some lights on this?
Thanks,

Hi,
I am interested using Neural Network type of tools to do classification in
Mahout. I wonder if these methods are finished in Mahout 0.8. On Mahout
website, it still says open.
Thanks,
Ying
