QA-MoE: Towards a Continuous Reliability Spectrum with Quality-Aware Mixture of Experts for Robust Multimodal Sentiment Analysis
Multimodal Sentiment Analysis (MSA) aims to infer human sentiment from textual, acoustic, and visual signals. In real-world scenarios, however, multimodal inputs are often compromised by dynamic noise or modality missingness. Existing methods typically treat these imperfections as discrete cases or assume fixed corruption ratios, which limits their adaptabil-ity to continuously varying reliability conditions. To address this, we first introduce a Continuous Reliability Spectrum to unify missingness and quality degradation into a sin-gle framework. Building on this, we propose QA-MoE, a Quality-Aware Mixture-of-Experts framework that quantifies modality reliability via self-supervised aleatoric uncertainty. This mechanism explicitly guides expert routing, en-abling the model to suppress error propagation from unreliable signals while preserving task-relevant information. Extensive experiments indicate that QA-MoE achieves competitive or state-of-the-art performance across diverse degradation scenarios and exhibits a promising One-Checkpoint-for-All property in practice.
Executive Impact
QA-MoE dramatically enhances Multimodal Sentiment Analysis (MSA) by introducing a continuous reliability spectrum, allowing for adaptive performance across diverse real-world data imperfections. This results in significant accuracy improvements and a robust 'One-Checkpoint-for-All' capability, drastically reducing operational complexity and ensuring reliable sentiment understanding in dynamic environments.

| C-MIB | 84.7 | 83.9 |
| MM-Boosting | 85.3 | 84.8 |
| SAM-LML | 87.8 | 86.9 |
| QA-MoE (Ours) | 88.4 | 87.6 |
0.9%
Performance lead over SAM-LML at severe noise levels (λ=0.7).
The framework maintains a low computational cost of 4.33 GFLOPs per sample and high throughput (1,510 samples/sec), making it suitable for real-time deployment.
Real-time Deployment Efficiency
Scenario: A financial institution needs to analyze live customer feedback streams (text, audio, video) to detect sentiment shifts instantly, even with varying data quality due to network fluctuations and background noise. Traditional models fail under these 'in-the-wild' conditions, requiring frequent retraining or performing poorly.
Solution: QA-MoE's 'One-Checkpoint-for-All' capability and efficient sparse expert activation allow a single model to adapt dynamically. It processes imperfect inputs by quantifying modality reliability via self-supervised aleatoric uncertainty, routing signals to specialized experts, and suppressing unreliable signals without needing retraining for each noise level.
Outcome: The institution successfully deploys QA-MoE, achieving 1,510 samples/sec throughput and maintaining high accuracy despite dynamic noise. This leads to a significant reduction in operational overhead and enables proactive customer support, preventing potential churn by identifying negative sentiment early.
