First Place Solution to the Multiple-choice Video QA Track of The Second Perception Test Challenge
<|reference_start|>First Place Solution to the Multiple-choice Video QA Track of The Second Perception Test Challenge: In this report, we present our first-place solution to the Multiple-choice Video Question Answering (QA) track of The Second Perception Test Challenge. This competition posed a complex video understanding task, requiring models to accurately comprehend and answer questions about video content. To address this challenge, we leveraged the powerful QwenVL2 (7B) model and fine-tune it on the provided training set. Additionally, we employed model ensemble strategies and Test Time Augmentation to boost performance. Through continuous optimization, our approach achieved a Top-1 Accuracy of 0.7647 on the leaderboard.<|reference_end|>
