Papers with sequence-to-sequence architectures
Extractive Summarization with Text Generator (2024.naacl-long)
Copied to clipboard
| Challenge: | Existing extractive systems lack gold training signals, thereby hindering learning of extractive models. |
| Approach: | They propose to use text generators to train extractive summarizers by approximating outputs of abstractive summaries. |
| Outcome: | The proposed method can be used to train extractive summarizers without training . it is shown that the approximated summaries correlate positively with the auxiliary summary outputs. |
Exploring Unsupervised Pretraining Objectives for Machine Translation (2021.findings-acl)
Copied to clipboard
| Challenge: | Unsupervised cross-lingual pretraining has significantly reduced the need for large parallel data. |
| Approach: | They compare unsupervised cross-lingual pretraining with masking and reconstructing inputs in the decoder to produce real sentences. |
| Outcome: | The proposed methods produce inputs resembling real (full) sentences, by reordering and replacing words based on their context. |
Revisiting Character-Based Neural Machine Translation with Capacity and Compression (D18-1)
Copied to clipboard
| Challenge: | Translating characters instead of words or word-fragments can simplify the processing pipeline but results in longer sequences . |
| Approach: | They propose to use sequence-to-sequence architectures of sufficient depth to solve the problem . they also evaluate the performance versus computation time tradeoffs they offer . |
| Outcome: | The proposed models outperform models operating over word fragments in character-level NMT, the authors show . they also show that the proposed models do not match the performance of their deep character baseline model . |
Multimodal Transformer Networks for End-to-End Video-Grounded Dialogue Systems (P19-1)
Copied to clipboard
| Challenge: | Existing work on video-grounded dialogue systems is limited by feature space and semantic information. |
| Approach: | They propose multimodal transformer networks to encode videos and incorporate information from different modalities. |
| Outcome: | The proposed system generates appropriate conversational response to queries of humans based on visual and audio aspects of a given video . it also generalizes to another multimodal visual-grounded dialogue task, and obtains promising performance. |
Transformers for Bridging Persian Dialects: Transliteration Model for Tajiki and Iranian Scripts (2024.lrec-main)
Copied to clipboard
| Challenge: | Despite its profound linguistic and cultural significance, Tajiki Persian remains a low-resource language with scant digitized datasets for computational applications. |
| Approach: | They propose to use Shahnameh, a seminal Persian epic poem, to train and assess Tajiki Persian transliteration models using two prominent sequence-to-sequence architectures: GRU with attention and transformer. |
| Outcome: | The proposed model outperforms pre-trained models with attention and transformer. |
