[0058] figure 1 It is a flowchart of a zero-sample cross-modal retrieval method based on multimodal feature synthesis in the present invention.
[0059] In this example, if figure 1 As shown, a zero-sample cross-modal retrieval method based on multimodal feature synthesis of the present invention comprises the following steps:
[0060] S1. Extract multimodal data features
[0061] Multimodal data includes images, text, etc. These raw data are expressed in a way that humans can accept, but computers cannot directly process them. Their features need to be extracted and expressed in numbers that computers can process.
[0062] Download N sets of multimodal data containing images, texts, and image and text shared category labels. These data belong to C categories, and images and texts under each category have shared category labels. Then use the convolutional neural network VGG Net to extract image features v i , using network Doc2vec to extract text features t i , using the ...
