Papers with relative position encoding
PoD: Positional Dependency-Based Word Embedding for Aspect Term Extraction (2020.coling-main)
Copied to clipboard
| Challenge: | Existing word embeddings that capture the contextual information only produce moderate results in aspect term extraction. |
| Approach: | They propose a positional dependency-based word embedding which takes both dependency context and positional context into account for aspect term extraction. |
| Outcome: | The proposed method outperforms other embedding methods in aspect term extraction. |
Better Pre-Training by Reducing Representation Confusion (2023.findings-eacl)
Copied to clipboard
| Challenge: | Existing methods to improve pre-trained language models address information confusion in position encoding and model representations. |
| Approach: | They propose two techniques to improve pre-trained language models by decoupling directions and auxiliary regularizers. |
| Outcome: | The proposed techniques can improve pre-trained language models on GLUE benchmarks. |
Flat Multi-modal Interaction Transformer for Named Entity Recognition (2022.coling-1)
Copied to clipboard
| Challenge: | Named entity recognition (MNER) aims at identifying entity spans and recognizing their categories in social media posts with the aid of images. |
| Approach: | They propose to use sentences and general domain words to obtain visual cues to transform the fine-grained semantic representation of vision and text into a unified lattice structure and leverage entity boundary detection as an auxiliary task to alleviate visual bias. |
| Outcome: | The proposed method achieves state-of-the-art on two benchmark datasets. |
Watermarking with Low-Entropy POS-Guided Token Partitioning and Z-Score-Driven Dynamic Bias for Large Language Models (2025.findings-emnlp)
Copied to clipboard
| Challenge: | Existing watermarking methods reduce the fidelity of semantics in LLMs . |
| Approach: | They propose a low-entropy token partitioning mechanism and z-score-driven dynamic bias mechanism to enhance semantics. |
| Outcome: | The proposed framework improves semantic fidelity and robustness against bias sparsity attacks. |
PermuteFormer: Efficient Relative Position Encoding for Long Sequences (2021.emnlp-main)
Copied to clipboard
| Challenge: | Existing Transformers that scale to long sequences are not compatible with relative position encoding. |
| Approach: | They propose a Performer-based model with relative position encoding that scales linearly on long sequences. |
| Outcome: | The proposed model outperforms performer on long sequences with no computational overhead and outperformed vanilla Transformer on most of the tasks. |
