DCA: Diversified Co-Attention towards Informative Live Video Commenting
Table 4: Experiment results of the ablation study. CoAttn denotes the traditional co-attention mechanism. Ortho. represents parameter orthogonalization. ✔ means including this module/method in the model.

In order to better understand the efficacy of the proposed methods, we further conduct an ablation study on different settings of our model. We also use the traditional co-attention model for comparison.
