Learning Question-Guided Video Representation for Multi-Turn Video Question Answering
Table 3: Ablation study on the AVSD validation set. We observe that the performance degrades when either of both of the question-guided per-token visual feature summarization (TokSumm) and feature gating (Gating) techniques are removed.

We perform ablation experiments on the validation set in the multi-turn VideoQA scenario to analyze the effectiveness of the two techniques in the question-guided video representation module.
