摘要:

多模式学习的目标是使用多模式提供的相关任务的补充信息,以实现可靠和强大的性能。最近,深度学习通过允许在中间特征水平中的信息融合,在多模态学习中取得了显著的改进。本文解决了在存在不完美模态的情况下设计鲁棒的深度多模态学习架构的问题。我们引入了用于目标检测的深度融合架构,该架构使用单独的卷积神经网络(CNN)处理每种模态,并通过组合CNN的中间特征来构建联合特征图。为了提高对退化模态的鲁棒性,我们采用了门控信息融合(GIF)网络,该网络根据待融合的输入特征图对每个模态的贡献进行加权。权重通过卷积层确定,然后是sigmoid函数,并以端到端的方式与信息融合网络一起训练。我们的实验表明,建议GIF网络提供了额外的架构灵活性,以实现强大的性能,在处理一些退化的方式,并显示出显着的性能改善的基础上Single Shot Detector(SSD)的KITTI数据集使用建议的融合网络和数据增强计划。

英文摘要:

The goal of multi-modal learning is to use complimentary information on the relevant task provided by the multiple modalities to achieve reliable and robust performance. Recently, deep learning has led significant improvement in multi-modal learning by allowing for the information fusion in the intermediate feature levels. This paper addresses a problem of designing robust deep multi-modal learning architecture in the presence of imperfect modalities. We introduce deep fusion architecture for object detection which processes each modality using the separate convolutional neural network (CNN) and constructs the joint feature map by combining the intermediate features from the CNNs. In order to facilitate the robustness to the degraded modalities, we employ the gated information fusion (GIF) network which weights the contribution from each modality according to the input feature maps to be fused. The weights are determined through the convolutional layers followed by a sigmoid function and trained along with the information fusion network in an end-to-end fashion. Our experiments show that the proposed GIF network offers the additional architectural flexibility to achieve robust performance in handling some degraded modalities, and show a significant performance improvement based on Single Shot Detector (SSD) for KITTI dataset using the proposed fusion network and data augmentation schemes.
