---------------------------------
Fix Version/s: 1.1.0
> Standardize input/output format for vectors and labeled points
> --------------------------------------------------------------
>
> Key: SPARK-1752
> URL: https://issues.apache.org/jira/browse/SPARK-1752
> Project: Spark
> Issue Type: New Feature
> Components: MLlib
> Reporter: Xiangrui Meng
> Assignee: Xiangrui Meng
> Fix For: 1.1.0
>
>
> We should standardize the text format used to represent vectors and labeled
> points. The proposed formats are the following:
> 1. dense vector: [v0,v1,..]
> 2. sparse vector: (size,[i0,i1],[v0,v1])
> 3. labeled point: (label,vector)
> where "(..)" indicates a tuple and "[...]" indicate an array. Those are
> compatible with Python's syntax and can be easily parsed using `eval`.
