Zusammenfassung:Video memorability prediction aims to quantify the credibility of being remembered according to the video content, which provides significant value in advertising design, social media recommendation, and other applications. However, the main attributes that affect the memorability prediction have not been determined so that making the design of the prediction model more challenging. Therefore, in this study, we analyze and experimentally verify how to select the most impact factors to predict video memorability. Furthermore, we design a new framework, Adaptive Multi-modal Ensemble Network, based on the chosen vital impact factors to predict video memorability efficiently. Specifically, we first conduct three main impact factors that affect video memorability, i.e., temporal 3D information, spatial information and semantics derived from video, image and caption, respectively. Then, the Adaptive Multi-modal Ensemble Network integrates the three individual base learners (i.e., ResNet3D, Deep Random Forest and Multi-Layer Perception) into a weighted ensemble framework to score the video memorability. In addition, we also design an adaptive learning strategy to update the weights based on the importance of memorability, which is predicted by the base learners rather than assigning weights manually. Finally, the experiments on the public VideoMem dataset demonstrate that the proposed method provides competitive results and high efficiency for video memorability prediction.
