Papers with modality-specific representations
ConFEDE: Contrastive Feature Decomposition for Multimodal Sentiment Analysis (2023.acl-long)
Copied to clipboard
| Challenge: | Multimodal sentiment analysis aims to predict the sentiment of video content. |
| Approach: | They propose a framework that performs contrastive representation learning and contrastive feature decomposition to enhance the representation of multimodal information. |
| Outcome: | The proposed framework outperforms baseline methods on CH-SIMS, MOSI and MOSEI datasets on a range of metrics. |
X-FLoRA: Cross-modal Federated Learning with Modality-expert LoRA for Medical VQA (2025.emnlp-main)
Copied to clipboard
| Challenge: | Medical visual question answering (VQA) and federated learning (FL) are important tools for privacy-preserving collaborative learning. |
| Approach: | They propose a cross-modal FL framework that uses modality-expert low-rank adaptation for medical visual question answering (VQA) X-FLoRA enables the synthesis of images from one modality to another without requiring data sharing . |
| Outcome: | Experiments show that X-FLoRA outperforms existing FL methods in terms of performance . XFLorage enables synthesis of images from one modality to another without data sharing . |
CLASP: Cross-modal Alignment Using Pre-trained Unimodal Models (2024.findings-acl)
Copied to clipboard
| Challenge: | Recent advances in speech-text pretraining rely on parallel speech- text data . however, data accessibility is a challenge due to the limited data available. |
| Approach: | They propose a framework for jointly performing speech and text processing without parallel corpora during pre-training but only downstream. |
| Outcome: | The proposed framework extracts distinct representations for speech and text, aligning them effectively in a newly defined space using a multi-level contrastive learning mechanism. |
Conversation Understanding using Relational Temporal Graph Neural Networks with Auxiliary Cross-Modality Interaction (2023.emnlp-main)
Copied to clipboard
| Challenge: | Emotion recognition is a crucial task for human conversation understanding . multimodal data, e.g., language, voice, and facial expressions, add complexity to the task. |
| Approach: | They propose a relational temporal Graph Neural Network with Auxiliary Cross-Modality Interaction framework that captures conversation-level cross-modality interactions and utterance-level temporal dependencies with modality-specific manner for conversation understanding. |
| Outcome: | The proposed framework captures conversation-level cross-modality interactions and utterance-level temporal dependencies with the modality-specific manner for conversation understanding. |
