| Abstract(in English) | Binary hashing has been widely used for Approximate Nearest Neighbor (ANN) search due to fast query speed and less storage cost. It is important for hashing functions to preserve a similarity of data space. We introduce a novel concept for preserving the similarity, a robustness index and an error cost function, and propose a hashing function learning method by optimizing the cost function with an assumption the data has Gaussian probability density function. Furthermore, we expand this method to learn a sparse hash function for faster coding. It is demonstrated that proposed methods have comparable level of similarity preservation to the existing methods. |
