1. A method for image search, comprising:
receiving a query text;
processing the query text to obtain a first multi-dimensional word vector;
performing, with a text gated network in a dual gate network, a first weighted operation on the first multi-dimensional word vector to obtain a second multi-dimensional word vector; and
searching for at least one target image according to the second multi-dimensional word vector and a second multi-dimensional visual vector for each of a plurality of images in an image file, wherein the second multi-dimensional visual vector for each of the plurality of images is obtained by performing, with a visual gated network in the dual gate network, a second weighted operation on a first multi-dimensional visual vector for each of the plurality of images, and the second multi-dimensional word vector and the second multi-dimensional visual vector for each of the plurality of images are in a same space.
