auto-arima in arima model

Path Finder

i am creating a model for the prediction of license usage in our environment.

tried many combination(around 25) of p,d,q for ARIMA, got few results which are best among the rest .

i want to know is it possible to use auto-arima in splunk?
if yes the please share the SPL.

Thanks in advance

auto Arima is not there in MLTK today but I would suggest to look into the new statespace algorithm provided out of box in MLTK.

as in Kalman filter?

actually not able to do much experiments with kalman filter and with default parameters i am not getting satisfactory results.

What parameters you're looking for? you can check the documentation here : https://docs.splunk.com/Documentation/MLApp/5.1.0/User/Algorithms#StateSpaceForecast

Also, Arima ( not auto arima) is available out of the box in MLTK. Check that option too.

It is Kalman filter with an ability to save and reuse the model..what's your usecases?

i want to predict the license usage in my environment.
so my dataset is simple with 2 fields,
"date" and "license used on that date".

Auto-ARIMA is supported in other languages like R, however, I don't see a way to use it out of the box with Splunk MLTK.

Of course, one can always add a custom algorithm to the MLTK. I'd love to know as well how one can use auto-ARIMA without writing any custom code.
