This research addresses a critical gap in multimodal sentiment analysis by proposing a method to reconstruct missing semantic information when text, audio, or visual cues are incomplete. By jointly optimizing sentiment prediction with a novel completeness estimation metric, the approach stabilizes multi-task learning and improves robustness against real-world data noise. The work represents a significant step forward in Machine Learning for handling imperfect input modalities without relying solely on dominant textual features.
Robust Multimodal Sentiment Analysis with Incomplete Modalities via Semantic-aware Completeness based Reconstruction
arXiv:2609.10950v1 Announce Type: cross Abstract: Recent multimodal sentiment analysis studies increasingly adopt text-centric fusion approaches to exploit the rich sentiment information inherent in the textual modality. However, these approaches often suffer from performance degradation during inference due to partially missing or noisy data in real-world scenarios, especially when sentiment-related cues are missing. To address this issue, we introduce a new completeness estimation approach that quantifies the degree of sentiment-relevant information preserved in incomplete data to guide the reconstruction of missing semantics. Furthermore, we propose a training strategy that stabilizes multi-task learning while jointly optimizing sentiment prediction and completeness estimation. Extensive experiments and in-depth analyses on three benchmark datasets demonstrate that the proposed approach enables more accurate semantic reconstruction, leading to more precise sentiment prediction.
