In our clusters, number of containers we can get is high but memory
per container is low : which is why avg_nodes_not_hosting data is
rarely zero for ML tasks :-)
To update - to unblock our current implementation efforts, we went
with broadcast - since it is intutively easier and minimal change;
Hi, Deb.
I don't quite understand the question. PLSA is an instance of matrix
factorization problem.
If you are asking about inference algorithm, we use EM-algorithm.
Description of this approach is, for example, here:

Best,
Thanks for the pointer...
Looks like you are using EM algorithm for factorization which looks similar
to multiplicative update rules
Do you think using mllib ALS implicit feedback, you can scale the problem
further ?
We can handle L1, L2, equality and positivity constraints in ALS now...As
long
I looked further and realized that ECOS used a mex file while PDCO is using
pure Matlab code. So the out-of-box runtime comparison is not fair.
I am trying to generate PDCO C port. Like ECOS, PDCO also makes use of
sparse support from Tim Davis.
Thanks.
Deb
Hi,
I found there is a invalid link in http://spark.apache.org/downloads.html .
The link for release note of Spark 1.0.0 indicates

invalid.
I think that is mistake for
