...Concretely, for the first step, we use Latent Dirichlet Allocation (LDA) [33] to model the corpus of all the captions in the training dataset of MSCOCO....

...The training samples for this regressor are the images from the same training dataset of MSCOCOwith the target outputs being the LDA-inferred scene vectors....
[...]
...Note that, representing images with global feature vectors and using the scene classifier provide an effective way to categorize test images where captions are not available (thus scene vectors cannot be inferred from LDA)....
