Documents Representation via Generalized Coupled Tensor Chain with the Rotation Group constraint (2021.findings-acl)
Copied to clipboard
| Challenge: | despite the diversity of linguistic structures, vector embedding models lack order-preserving properties . current methods for learning linguistic structure can be expensive and time-consuming . |
| Approach: | They propose a method for embedding documents and words in rotation group . they capture word order and higher-order word interactions . |
| Outcome: | The proposed model achieves the best results in document classification benchmarks. |
CTFN: Hierarchical Learning for Multimodal Sentiment Analysis Using Coupled-Translation Fusion Network (2021.acl-long)
Copied to clipboard
| Challenge: | Existing methods for multimodal sentiment analysis require all modalities as input, thus are sensitive to missing modality at predicting time. |
| Approach: | They propose to model bi-direction interplay via couple learning and exploit multiple bi-directional translations to exploit multimodal fusion embeddings. |
| Outcome: | The proposed framework achieves state-of-the-art or often competitive performance on two multimodal benchmarks with extensive ablation studies. |
