AWhat changed
Fitted boosted regression trees to LambdaRank update signals, supported warm-start adaptation from an existing ranker and enumerated rank-order crossing points for exact line search between two fixed rankers.
Scientific scope
Fitted boosted regression trees to LambdaRank update signals, supported warm-start adaptation from an existing ranker and enumerated rank-order crossing points for exact line search between two fixed rankers. Exact best mixing of two fixed rankers on finite labeled data is not global optimality over all boosted ensembles or guaranteed generalization. LambdaRank metric optimality is explicitly empirical. Online publication September3,2009 precedes the June2010 volume issue; year2009 follows primary publisher publication date.
