Ajay Bhat commented on FLINK-1750:
----------------------------------

I'd like to take up this issue, since the linear models seem to be nearly done. 
Does this have to be a Transformer?

> Add canonical correlation analysis (CCA) to machine learning library

> Canonical correlation analysis (CCA) [1] can be used to find correlated 
> features between two random variables. Moreover, CCA can be used for 
> dimensionality reduction.
> Maybe the work of Jia Chen and Ioannis D. Schizas [2] can be adapted to 
> realize a distributed CCA with Flink.
