For our video captioning as well as entailment generation results, we use four diverse automatic evaluation metrics that are popular for image/video captioning and language generation in general: METEOR (Denkowski and Lavie, 2014), BLEU-4 (Papineni et al., 2002), CIDEr-D (Vedantam et al., 2015), and ROUGE-L (Lin, 2004).
then the mixing ratio is defined as αv (αv+α f +αe) : Video Captioning Datasets We report results on three popular video captioning datasets.
