----------------------------------
Summary: Make convergence tolerance param in ANN default value
consistent with other algorithm using LBFGS
Key: SPARK-16653
URL: https://issues.apache.org/jira/browse/SPARK-16653
Project: Spark
Issue Type: Improvement
Reporter: Weichen Xu
The default value of convergence tolerance param in ANN is 1e-4,
but other algorithm (such as LinearRegression, LogisticRegression, and so on)
using LBFGS optimizers this param's default values are all 1e-6.
I think make them the same will be better.
