Reliability-aware Cross-sample Enhancement (RCE) is a framework for multimodal sentiment analysis that tackles noise and missing modalities by first applying an adaptive variational information bottleneck to compress unreliable modality information. It then retrieves high‑confidence, semantically consistent neighbors from a large candidate pool to enrich current representations, and finally fuses cross‑modal interactions through a multilevel reliability‑aware mechanism. Experiments show RCE consistently outperforms state‑of‑the‑art methods in full, noisy, and missing‑modality scenarios.

The paper critiques current optimization-based methods for balancing modalities in Multimodal Sentiment Analysis, arguing they overpromise and underdeliver. It introduces a unified evaluation framework that tests gradient- and loss-based balancing strategies, provides a theoretical diagnosis showing these methods conflate fitting speed with discriminative contribution, and proposes a research agenda for held‑out discriminative modality valuation. Experiments on CMU‑MOSI and CMU‑MOSEI demonstrate that no strategy consistently outperforms Late Concatenation, performance is highly sensitive to hyperparameters, and ratio calibration does not yield reliable gains, highlighting that loss is not utility and gradients are not importance.

arXiv:2607. 10599v1 Announce Type: new Abstract: Multimodal sentiment analysis relies on language, visual, and acoustic cues, but utterance-level modality quality may vary due to occlusion, background noise, motion blur, or imperfect transcripts, causing conventional fusion to over-trust unreliable modalities.

arXiv:2607. 08573v1 Announce Type: new Abstract: Multimodal emotion and sentiment recognition is commonly addressed by early fusion, which concatenates modalities before classification, or late fusion, which combines independently trained unimodal predictors.

arXiv:2606. 02679v1 Announce Type: new Abstract: Multimodal systems often benefit from combining information across language, sound, and visual streams, but this benefit is not guaranteed.
