📝 摘要(中文)
多模态特征融合通过整合不同模态的互补信息,有效捕捉现实数据中的复杂模式。然而,在许多应用中,如锅炉燃烧监测和设备故障,传感器采样频率不一致和网络延迟等问题导致模态缺失和时间异步。这些问题造成了不完整和无序的多模态数据。为了解决这些问题,本文提出了一种基于双学习的惩罚多对齐聚类模型DLPMAC。该模型通过双学习机制从每个模态中学习先验知识,保持语义一致性和结构相似性。同时,惩罚多对齐模块通过惩罚机制实现多对多数据对齐,提高了数据对齐的准确性。实验结果表明,DLPMAC在采样和聚类方面有效应对了数据对齐和融合挑战。

📄 摘要(原文)
Multimodal feature fusion can effectively capture complex patterns in real-world data by integrating complementary information from different modalities. However, in many applications, such as boiler combustion monitoring, equipment failure, inconsistent sensor sampling frequencies, and network delays often cause missing modalities and temporal asynchrony. These issues lead to incomplete and disorderly multimodal data. To address them, previous studies have proposed several data fusion methods that align cluster centers before fusion. However, these methods have two key limitations. First, they cannot guarantee accurate sample-level alignment of data pairs. Second, they do not address significant discrepancies in data sizes across different classes, which may affect subsequent fusion performance. To address these problems, we propose a dual-learning based penalized multi-align clustering model, named DLPMAC. The dual-learning mechanism enables the model to learn prior knowledge from each modality, including semantic and structural information. This helps preserve semantic consistency and structural similarity across modalities at both local and global levels. In addition, the penalized multi-align module performs multi-to-multi data alignment through a penalty mechanism. It allows one sample to form data pairs with different samples from other modalities, thereby improving data-pair alignment accuracy. The penalty mechanism also prevents data aggregation, avoiding the case where excessive samples are linked to a single sample. Experimental results demonstrate the effectiveness of DLPMAC in addressing data alignment and fusion challenges from both sampling and clustering perspectives.
