Re: Retrieving the PCA parameters in pyspark

Hi Rohit,

This is a known bug, but you can get these parameters if you use Scala
version.

Retrieving the PCA parameters in pyspark

[Rohit Girdhar]

Hi

I'm using PCA through the python interface for spark, as per the
instructions on this page:
https://spark.apache.org/docs/1.5.1/ml-features.html#pca

It works fine for learning the parameters and transforming the data.
However, I'm unable to find a way to retrieve the learnt PCA parameters. I
tried using model.params, but that returns an empty list. Is there some way
to retrieve these parameters (maybe through the py4j interface)?

Thanks
Rohit

Retrieving the PCA parameters in pyspark

[Rohit Girdhar]

Hi

I'm using PCA through the python interface for spark, as per the
instructions on this page:
https://spark.apache.org/docs/1.5.1/ml-features.html#pca

It works fine for learning the parameters and transforming the data.
However, I'm unable to find a way to retrieve the learnt PCA parameters. I
tried using model.params, but that returns an empty list. Is there some way
to retrieve these parameters (maybe through the py4j interface)?

Thanks
Rohit
