Wild guess maybe, but do you decode the json records in Python ? it could
be much slower as the default lib is quite slow.
If so try ujson [1] - a C implementation that is at least an order of
magnitude faster.

of
these regression algorithms, for example how to choose a good step and
number of iterations? I wonder if I'm using those right...
Thanks,

Printing the model show the intercept is always 0 :(
Should I open a bug for that ?

Hi list,
I'm benchmarking MLlib for a regression task [1] and get strange
results.
Namely
the ones column.
Does anyone here has had success with this code on real-world datasets ?

Well, why not, but IMHO MLLib Logistic Regression is unusable

Hi list,
I'm benchmarking MLlib for a regression task [1] and get strange results.
Namely, using RidgeRegressionWithSGD it seems the predicted points miss the
intercept:
{code}
val trainedModel = RidgeRegressionWithSGD.train(trainingData, 1000)
...
valuesAndPreds.take(10).map(t = println(t))
I'm interested in this topic too :)
Are the MLLib core devs on this list ?

Anyone knows anything about it? Or should I actually move this topic to a
MLlib specif mailing list? Any information is appreciated! Thanks!

Hi Sparkers,
We have a Storm cluster and looking for a decent execution engine for
machine learned models. What I've seen from MLLib is extremely positive,
but we can't just throw away our Storm based stack.
So my question is: is it feasible/recommended to train models in
Spark/MLLib and execute
,
which at least provides an online lda.

Is there a PR or issue where GBT / RF progress in MLLib is tracked ?
