Is it possible that after filtering the feature dimension changed?
This may happen if you use LIBSVM format but didn't specify the number
of features. -Xiangrui

Hi All,
I was able to run LinearRegressionwithSGD for a largeer dataset ( 2GB sparse).
I have now filtered the data and I am running regression on a subset of it (~
200 MB). I see this error, which is strange since it was running fine with the
superset data. Is this a formatting issue

Did you test different regularization parameters and step sizes? In
the combination that works, I don't see A + D. Did you test that
combination? Are there any linear

Hi All,I have following classes of features:
class A: 15000 featuresclass B: 170 featuresclass C: 900 featuresClass D: 6000

I use linear regression (over sparse data). I get excellent results with low
RMSE (~0.06) for the following combinations of classes:1. A + B + C 2. B + C +

Subject: MLlib Linear Regression Mismatch
Guys,
Obviously I am doing something wrong. May be 4 points are too small a
dataset.
Can you help me to figure out why the following doesn't work ?
a) This works :
data = [
LabeledPoint(0.0, [0.0]),
LabeledPoint(10.0, [10.0
to be 0.1 or 0.01?
Best,
Burak
