I suppose you're read the page
http://www.statmt.org/moses/?n=Moses.SparseFeatures
I small, fairly clear feature function that uses sparse feature is
TargetBigramFeature
The main thing to note
1. It has not dense feature, from the 0 in the constructor
TargetBigramFeature::TargetBigramFeature(const std::string &line)
:StatefulFeatureFunction(0, line)
2. In Evaluate(), adding a score to the score component is done by
calling
PlusEquals(this, sparse-feature-name, score);
For dense features, it would have been
PlusEquals(this, vector-of-scores);
