Describe the workflow you want to enable

I want to update the scorer.py and add a new function to it i.e., root_mean_square_log_error because I came across many contests where the main task is of finding root_mean_square_log_error(RMSLE). And scikit-learn initially do not have such inbuilt function.

Describe your proposed solution

Root Mean Square Log Error is nothing but the square root of Mean Square Log Error.

Additional context

I had implement the same in #20326

I agree that it would be useful, but we could implement it the same way RMSE is currently done with mean_squared_error(..., squared=False).

So +1 to add a squared option to mean_squared_log_error with a default to True.

Let's wait a day or two to see if there is other feedback.

Obviously, But I am considering mean_squared_log_error not mean_squared_error!

And according to my readings mean_squared_log_error has no parmaters like squared=. It is there in mean_squared_error but not in mean_squared_log_error . It will throw an error if we will try to adjust the parameter as 'squared=False'

The error will be:
mean_squared_log_error got an unexpected arguement 'squared'

Yes, but we could add that parameter.

Yes, sure! should we wait for other's opinion? :)
then we will go accordingly for its implementation!

I am +1 for supporting RMSLE by adding squared= to mean_squared_log_error.

Okay then I am moving forward to implement the squared= as parameter in `mean_squared_log_error'!

It would be great, if I can connect with someone via LinkedIn, email, etc , who will help me whenever I need help! :D

I had create a new branch named rmsle , and updated the code there! Please have a look.

PR is opened #20322
Why the tests is being failed on CircleCI, I am not getting this problem.
