Secondly, we incorporate the obtained semantic associations between visual attributes and object categories into a text-based topic model and extract descriptive latent topics from external textual knowledge ...
Experimental results show that the proposed model achieves better ability in describing object-related attributes and makes the inferred latent topics more descriptive. ...
