The MERSA Dataset and a Transformer-Based Approach for Speech Emotion Recognition (2024.acl-long)
Copied to clipboard
| Challenge: | Existing models for speech emotion recognition lack a comprehensive dataset to design accurate models. |
| Approach: | They propose to use a multimodal dataset to build a model that integrates pre-trained wav2vec 2.0 and BERT to learn hidden representations from fused representations of speech and text. |
| Outcome: | The proposed model predicts emotions on dimensions of arousal, valence, and dominance . it achieved competitive results on the MSP-PODCAST dataset . |
Mitigating Interviewer Bias in Multimodal Depression Detection: An Approach with Adversarial Learning and Contextual Positional Encoding (2025.findings-emnlp)
Copied to clipboard
| Challenge: | Clinical interviews are a standard method for assessing depression . however, these methods neglect the broader conversational context . |
| Approach: | They develop a multimodal dialogue-level transformer that captures the dynamics of dialogue within each interview . they also build an adversarial classifier with a gradient reversal layer to learn shared representations . |
| Outcome: | The proposed model captures the dynamics of dialogue within each interview using positional embedding and question context vectors. |
