Jinhong Ni, Yalong Bai, Wei Zhang, Ting Yao, Tao Mei

AI总结:

针对现有融合方法无法充分捕捉复杂模态间交互动态的问题,提出深度均衡(DEQ)多模态融合方法,通过寻找动态融合过程的不动点并自适应递归地建模特征相关性,在多个多模态基准上取得了最先进的性能。

摘要:

多模态融合整合了多种模态中存在的互补信息,近期受到了广泛关注。现有的多数融合方法要么在训练和推理期间学习固定的融合策略,要么只能在一定程度内融合信息。这类方案可能无法完全捕捉跨模态交互的动态特性,尤其是在进行信息丰富的多模态融合需要考虑复杂的模态内和模态间相关性时。在本文中,我们提出了一种面向多模态融合的新型深度均衡(DEQ)方法,该方法通过寻找动态多模态融合过程的不动点,并以自适应和递归的方式对特征相关性进行建模。这种新方式从低级到高级彻底编码了模态内和跨模态的丰富信息,以实现有效的下游多模态学习,并且可以轻松插入到各种多模态框架中。在BRCA、MM-IMDB、CMU-MOSI、SUN RGB-D和VQA-v2上的大量实验证明了我们DEQ融合的优越性。更值得注意的是,DEQ融合在多个多模态基准上始终取得最先进的性能。代码将会发布。

英文摘要:

Multimodal fusion integrates the complementary information present in multiple modalities and has gained much attention recently. Most existing fusion approaches either learn a fixed fusion strategy during training and inference, or are only capable of fusing the information to a certain extent. Such solutions may fail to fully capture the dynamics of interactions across modalities especially when there are complex intra- and inter-modality correlations to be considered for informative multimodal fusion. In this paper, we propose a novel deep equilibrium (DEQ) method towards multimodal fusion via seeking a fixed point of the dynamic multimodal fusion process and modeling the feature correlations in an adaptive and recursive manner. This new way encodes the rich information within and across modalities thoroughly from low level to high level for efficacious downstream multimodal learning and is readily pluggable to various multimodal frameworks. Extensive experiments on BRCA, MM-IMDB, CMU-MOSI, SUN RGB-D, and VQA-v2 demonstrate the superiority of our DEQ fusion. More remarkably, DEQ fusion consistently achieves state-of-the-art performance on multiple multimodal benchmarks. The code will be released.
