Abstract
A method of contrastive learning (CL) performed by at least one processor includes receiving, by at least one processor implementing a text-based transformer, a text title corresponding to an anchor, generating, by the at least one processor implementing the text-based transformer, a text representation of the text title, receiving, by at least one processor implementing an image-based transformer, a first image corresponding to the anchor, generating, by the at least one processor implementing the image-based transformer, a first image representation of the first image corresponding to the anchor, and constructing a positive pair between the text representation and the first image representation.
