Merge pull request #337 from yinxusen/mllib-16-bugfix
Mllib 16 bugfix
Bug fix: https://spark-project.atlassian.net/browse/MLLIB-16
Hi, I fixed the bug and added a test suite for `GradientDescent`. There are 2 checks in the test case. First, the final loss must be lower than the initial one. Second, the trend of loss sequence should be decreasing, i.e., at least 80% iterations have lower losses than their prior iterations.
Thanks!
