How do you calculate the Root Mean Squared Logarithmic Error in h2o?

Question

As mentioned, how to calculate that with a h2o model, what's the most optimum way to do this with a large volume of data

Answer 1

h2o doesn't currently have RMSLE implemented (only RMSE), but it makes sense to add. Here is the JIRA ticket where you can track the progress.

Update: Support has been added to implement RMSE from version 3.10.0.5.
