Yu Gong commented on SAMOA-54:
------------------------------
For example, I can define an interface of Model which can be serialized, and
contains the method as predict.
public interface Model extends Serializable {
double[] predict(Instance inst);
}
And for HoeffdingTreeModel, I can define it as:
public class HoeffdingTreeModel implements Model {
private Instances dataset;
private Node treeRoot;
public HoeffdingTreeModel(Instances dataset, Node treeRoot) {
this.dataset = dataset;
this.treeRoot = treeRoot;
}
public HoeffdingTreeModel() {
}
@Override
public double[] predict(Instance inst) {
double[] prediction;
// inst.setDataset(dataset);
FoundNode foundNode;
if (treeRoot != null) {
foundNode = treeRoot.filterInstanceToLeaf(inst, null, -1);
Node leafNode = foundNode.getNode();
if (leafNode == null) {
leafNode = foundNode.getParent();
}
prediction = leafNode.getClassVotes(inst, null);
} else {
int numClasses = dataset.numClasses();
prediction = new double[numClasses];
}
return prediction;
}
}
I can create the HoeffdingTreeModel object in
org.apache.samoa.learners.classifiers.trees.ModelAggregatorProcessor, and
output the object.
Can you give me some advice about it? Thanks a lot.
