Deep momentum uncertainty hashing

作者:

Highlights:

• We are the first to explore the uncertainty of hashing bits during approximate optimization. Depending on the magnitude of uncertainty, the corresponding hashing bits and input images receive different attention.

• We propose to explicitly model bit-level and image-level uncertainty, resorting to the output discrepancy between the hashing network and the momentum-updated network.

• Extensive experiments on the CIFAR-10, the NUS-WIDE, the MS-COCO, and the largescale Clothing1M datasets demonstrate that our method significantly improves retrieval performance when compared with state-of-the-art methods.
