Claim 16:
17. A method for indexing data, comprising:
determining a data property component of an objective function for indexing a dataset, the data property component configured to utilize a property of the dataset to group data of the dataset, and being determined by maximizing a variance of the dataset by applying a principal component analysis (PCA) and maximum variance unfolding (MVU) to reduce computational costs during the indexing, the maximizing the variance comprising applying the PCA, the applying the PCA comprising determining an eigenvector from a data covariance matrix with a largest corresponding eigenvector and MVU forming an inner product of a data matrix;
determining a supervised component of the objective function which utilizes supervision information to group data of the dataset; and
recursively optimizing the objective function using a processor based upon the data property component and the supervised component to partition a node into a plurality of child nodes.
