Abstract

To guarantee the relative similarity relationship among data pairs in the Hamming space and the Euclidean space is well consistent with each other, the proposed method established the relative similarity preserving constraint based on quartic tuples. As a result, the power of preserving relative similarity was effectively enhanced. Furthermore, it utilized the tensor ordinal graph to collect the data pairs which satisfied specify ordinal relation. Due to the above measure, it reduced the training time complexity. During the training process, the weights of the data points whose relative similarity not well preserved were iteratively updated to induce the attention. Finally, it minimized the residual performance loss, and boosted the ANN search performance. The comparative experimental results on three large scale datasets show that the proposed method achieves the best ANN search performance, and it is superior to the state-of-the-art methods.
