How do you get sklearn algorithm to work in Splunk?

Explorer

I have added another algorithm SVR in Splunk Enterprise with the way on the website below, and it works.
But I'm confused about the commands fit and apply.
I've read the user guide http://docs.splunk.com/Documentation/MLApp/4.0.0/User/Understandfitandapply

and https://docs.splunk.com/Documentation/MLApp/4.0.0/API/Writeanalgorithmclass.

I know SVR has fit command.

For example:
estimator = SVR()
estimator.fit(trainfeature, trainlabel) #training process

However, I want to predict another feature "testfeature", and I must use the command below
estimator.predict(test
feature) #prediction process

Now, here is the quastion, where is the apply?

How does it works?

Could anyone help me?

@ rickyhsu7,

You fit an algorithm and apply a model.
In simple words, we apply the algorithm on our test data, then if things go well, we give a logical name to the whole thing which is model name. then when we actually have to use that model to our final dataset, we use apply.

Does it make sense?
