Hi All,
In LTR for MultipleAdditiveTreeModel what is the purpose of adding
NODE_SPLIT_SLACK
to the threshold?
Reference: org.apache.solr.ltr.model.MultipleAdditiveTreesModel
private static final float NODE_SPLIT_SLACK = 1E-6f;
public void setThreshold(float threshold) { this.threshold = threshold +
NODE_SPLIT_SLACK; }
We have a feature which can return 0.0 or 1.0
And model with this tree:
is_xyz_feature,threshold=0.99999994,left=0.0010180053,right=-0.0057609854
However when Solr actually scores it it is taking it as follows
is_xyz_feature:1.0<= 1.000001, Go Left
So all the time it goes to left which is incorrect.
Thanks,
Roopa
