Unpaired Image Captioning via Scene Graph Alignments

Understand

Most of current image captioning models heavily rely on paired image-caption datasets.

• However, getting large scale image-caption paired data is labor-intensive and time-consuming.
• In this paper, we present a scene graph-based approach for unpaired image captioning.
• Our framework comprises an image scene graph generator, a sentence scene graph generator, a scene graph encoder, and a sentence decoder.
