The invention discloses a noisy
label cross-
modal retrieval method based on neighborhood
perception instance refining, which comprises the following steps of: performing
feature extraction on input noisy cross-
modal data, and mapping the data to a shared
semantic space; constructing a cross-
modal boundary keeping module, and enhancing the global discrimination capability of feature representation through global mechanism regularization; constructing a cross-modal neighborhood
consensus module, generating a soft
label based on the cross-modal neighborhood
consensus module, dynamically dividing a
data set, and performing a targeted optimization strategy on the
data set; integrating the loss functions of all the modules to perform end-to-end joint optimization, and training to obtain a cross-modal retrieval model with high robustness to
noise tags; and efficient cross-modal retrieval is realized. According to the method, the robust learning method, the
instance selection method and the
label calibration method are integrated together, so that maximum utilization and fine
processing of all training data are realized, and the retrieval performance in a high-
noise environment is remarkably improved.
