Spark MLlib does not support boxed constraints on model coefficients
currently.

Thanks

Linear regression, weights constraint

2016-08-15 Thread letaiv 
Hi all, 

Is there any approach to add constrain for weights in linear regression?
What I need is least squares regression with non-negative constraints on the
coefficients/weights. 

Thanks in advance.
