PCA facilitates dimensionality reduction for of64258ine clus tering of users and rapid computation of recommendations For a database of users standard nearestneighbor tech niques require processing time to compute recom mendations whereas Eigentaste We extend this concept to robotic hands and show how a similar dimensionality reduction can be de64257ned for a number of different hand models This framework can be used to derive planning algorithms that produce stable grasps even for highly compl unigeit Abstract In this paper data dimensionality estimation methods are reviewed The estima tion of the dimensionality of a data set is a classical problem of pattern recognition There are some good reviews 1 in literature but they do not include m SVD & CUR.
