Hi,
Recently, I am trying to write some codes so that it can be easier to serialize
SAMOA machine learning model such as Hoeffding Tree, Clustream and so on. And
make it easier to use the model in some external environment. I think it's
quite useful.
However, I meet some problem about Hoeffding Tree in SAMOA. I print the
**prediction** of each class (which is a double array) for some instances, and
the true number of class for each instance is 2.
But some **predictions** only contains 1 score, and others contains two. I am
wondering what is the meaning about the **predictions** containing 1 score. You
can see in the following figure.
I am looking forward hearing from you. And thanks all of you for building this
awesome platform for streaming data mining.
Thanks,
Yu
