AI总结:

针对视频描述任务,提出基于Transformer的CLearViD模型,结合两种课程学习策略与Mish激活函数,在两个数据集上的准确率和多样性均超越现有SOTA模型。

摘要:

视频描述任务旨在自动生成连贯的自然语言句子,来叙述给定视频的内容。我们提出了CLearViD,这是一种用于生成视频描述的基于Transformer的模型,它利用课程学习来完成该任务。具体而言,我们研究了两种课程策略:(1)通过向视频数据逐步施加高斯噪声,让模型逐步接触更具挑战性的样本;(2)在训练过程中通过dropout逐步降低网络容量。这些方法能让模型学习到更鲁棒、更具泛化性的特征。此外,CLearViD采用了Mish激活函数,该函数具备非线性和非单调性,有助于缓解梯度消失问题。我们开展了大量实验与消融研究,验证了所提模型的有效性。在ActivityNet Captions和YouCook2这两个数据集上的结果表明,CLearViD在准确率和多样性指标上均显著优于现有最先进模型。

英文摘要:

Video description entails automatically generating coherent natural language sentences that narrate the content of a given video. We introduce CLearViD, a transformer-based model for video description generation that leverages curriculum learning to accomplish this task. In particular, we investigate two curriculum strategies: (1) progressively exposing the model to more challenging samples by gradually applying a Gaussian noise to the video data, and (2) gradually reducing the capacity of the network through dropout during the training process. These methods enable the model to learn more robust and generalizable features. Moreover, CLearViD leverages the Mish activation function, which provides non-linearity and non-monotonicity and helps alleviate the issue of vanishing gradients. Our extensive experiments and ablation studies demonstrate the effectiveness of the proposed model. The results on two datasets, namely ActivityNet Captions and YouCook2, show that CLearViD significantly outperforms existing state-of-the-art models in terms of both accuracy and diversity metrics.
