Claim Text:
1. A non-transitory computer readable storage medium comprising a computer readable program for indexing data, wherein the computer readable program when executed on a computer causes the computer to perform the steps of: formulating an objective function to index a dataset, a portion of the dataset including supervision information; determining a data property component of the objective function which utilizes a property of the dataset to group data of the dataset, wherein determining the data property component includes maximizing a variance of the dataset, the maximizing the variance including applying maximum variance unfolding by forming a projection as an inner product of a data matrix and a learned partition hyperplane and maximizing overall pairwise distances in a projected space; determining a supervised component of the objective function which utilizes the supervision information to group data of the dataset; and 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.
