> 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
> Components: ML, Optimizer
> Reporter: Weichen Xu
> Fix For: 2.1.0
>
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> 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.
