[Java-ML-support] How to save a model file for later use

[Ritesh <rit...@gm...>]

H
​i,

I was ​wondering if there is some way to save something like a model file
on the disk after we build a classifier from a dataset. The API
documentation lists the methods "buildClassifier" which basically trains
and builds any classifier and "classify" which classifies an instance using
this classifier. So effectively it means I have to build a classifier every
time I want to classify some instances which takes up lot of resource. Is
there a way to save the classifier after "buildClassifier" which could be
loaded into the memory any time we want to classify some instance?

Regards,

Ritesh

You can simply serialize the classifier object after buildClassifier and 
it will retain it's state. Just deserialize it back when you need it.

cheers,
Thomas
