A General Magnitude-Preserving Boosting Algorithm for Search Ranking
Directed distance function (DDF) magnitude-preserving pairwise-preference
2012/12/3
Traditional boosting algorithms for the ranking problems usually employ the pairwise approach and convert the document rating preference into a binary-value label, like RankBoost. However, such a pair...
A Novel Volumetric Shape from Silhouette Algorithm Based on a Centripetal Pentahedron Model,
Volumetric Shape Silhouette Algorithm Centripetal Pentahedron Model
2010/12/16
In this paper we present a novel volumetric shape from silhouette algorithm based on a centripetal pentahedron model. The algorithm first partitions the space with a set of infinite triangular pyramid...
