AMB-DSGDN: Adaptive Modality-Balanced Dynamic Semantic Graph Differential Network for Multimodal Emotion Recognition
The paper proposes AMB-DSGDN, an Adaptive Modality-Balanced Dynamic Semantic Graph Differential Network for multimodal emotion recognition. It addresses limitations in existing approaches by introducing modality-specific subgraphs, a differential graph attention mechanism to filter noise and capture dynamic emotional dependencies, and an adaptive modality balancing mechanism to manage modality contributions. This aims to improve the accuracy and robustness of emotion recognition in complex conversational settings.

Dynamic Emotional Dependency Modeling
The AMB-DSGDN introduces modality-specific subgraphs (intra-speaker and inter-speaker) combined with a differential graph attention mechanism. This novel approach explicitly models temporal evolution and interactive relationships, effectively filtering shared noise and amplifying context-relevant emotional signals.

Adaptive Modality Contribution Balancing
A key innovation is the adaptive modal dropout mechanism. This dynamically estimates a dropout probability for each modality based on its real-time contribution to emotion modeling, mitigating the overwhelming influence of dominant modalities (e.g., text) and ensuring balanced information fusion.
| Noise Level | AMB-DSGDN Performance (wa-F1) |
|---|---|
| 0.0 | 75.64% (IEMOCAP), 66.18% (MELD) |
| 0.3 | 75.30% (IEMOCAP), 65.26% (MELD) |
| 0.7 | 74.44% (IEMOCAP), 64.92% (MELD) |
Enhanced Noise Robustness Across Modalities
Experiments show that AMB-DSGDN maintains stable performance even with significant Gaussian noise injected into multimodal features, demonstrating its ability to filter redundant information and preserve discriminative emotional representations under challenging conditions.
Scalable Long-Sequence Dialogue Emotion Recognition
Problem: Traditional models struggle with context forgetting and performance degradation in long dialogues.
Solution: AMB-DSGDN uses dynamic cross-modal contribution balancing and differential relation graph modeling to maintain stable emotion recognition, even over 20-50 utterance sequences.
Benefit: Enables robust and adaptive emotional understanding in extended conversational AI applications.
Scalable Long-Sequence Dialogue Emotion Recognition
The model demonstrates superior performance on long-sequence dialogue subsets of IEMOCAP, effectively capturing long-range contextual dependencies and maintaining stable emotion recognition over extended interactions. This is crucial for applications like customer service bots or mental health monitoring where conversation length is significant.
| Metric | DiffRGCN Overhead (IEMOCAP) | Modality Balancing Overhead (IEMOCAP) |
|---|---|---|
| Inference Time | +11.70% | +21.45% |
| Throughput | -12.86% | -7.45% |
| Batch Time | +17.22% | +10.50% |
Computational Overhead Analysis
While AMB-DSGDN introduces additional computational overhead due to differential graph attention and relational embeddings, this is managed within acceptable limits, especially when compared to performance gains. The window-based subgraph modeling helps maintain scalability.
