Hi Filipp,
MLlib’s LR implementation did the same way as R’s glmnet for standardization.
Actually you don’t need to care about the implementation detail, as the
coefficients are always returned on the original scale, so it should be return
the same result as other popular ML libraries.

To optimize non-smooth function on LBFGS really should be considered carefully.

Do you want to get sparse model that most of the coefficients are zeros? If
yes, using L1 regularization leads to sparsity. But the
LogisticRegressionModel coefficients vector's size is still equal with the
number of features, you can get the non-zero elements manually. Actually,
it would be a

It's a good question and I had similar requirement in my work. I'm copying
the implementation from mllib to ml currently, and then exposing the
maximum log likelihood. I will send this PR soon.
Thanks.

Hi All,
Many users have requirements to use third party R packages in

For example, you should to mess with the IT/administrators of the cluster

I run KMeans with probes and found that takeSample() was called only once
actually. It looks like this issue was caused by mistake display at Spark
UI.

Hi Hao,
HashingTF directly apply a hash function (Murmurhash3) to the features to
determine their column index. It excluded any thought about the term
frequency or the length of the document. It does similar work compared with
sklearn FeatureHasher. The result is increased speed and reduced
DataFrame is a kind of special case of Dataset, so they mean the same thing.
Actually the ML pipeline API will accept Dataset[_] instead of DataFrame in
Spark 2.0.
We can say that MLlib will focus on the Dataset-based API for futher
development more accurately.
Thanks

You can combine the columns which are need to be normalized into a vector
by VectorAssembler and do normalization on it.
Do another assembling for columns should not be normalized. At last, you
can assemble the two vector into one vector as the feature column and feed
it into model training.

This is because we do not have excellent coverage for Java-friendly
wrappers.
I found we only implement JavaParams who is the wrappers of Scala Params.
We still need Java-friendly wrappers for other traits who extends from
Scala Params.
For example, in Scala we have:

You means the SVDPlusPlus in GraphX? If you want to use SVD++ to train CF
model, I recommend you to use ALS which is more efficiency and has python
interface.

Hi All,
LogisticRegressionWithLBFGS set useFeatureScaling to true default which can
improve the convergence during optimization.
However, other model training method such as LogisticRegressionWithSGD does
not set useFeatureScaling to true by default and the corresponding set
function is private
by multiply a constant to the weights.
Sincerely,
DB Tsai
