| Challenge: | Task-oriented dialog (TOD) is one of the central objectives, hallmarks, and applications of machine intelligence. |
| Approach: | They propose a multilingual, multi-domain, multiparallele ToD dataset that offers culturally adapted dialogs in 4 languages for training and evaluation of multilingual and cross-lingual systems. |
| Outcome: | The proposed dataset is large-scale and culturally adapted to enable training and evaluation of multilingual and cross-lingual ToD systems. |

| Challenge: | Existing systems trained for Arabic or Turkish using annotated data fully parallel to English ToD data still exhibit diminished ToD task performance. |
| Approach: | They define new quantitative measures of absolute and relative equivalence in system performance, capturing disparities across languages and within individual languages. |
| Outcome: | The proposed measures capture disparities across languages and within individual languages. |
Text-to-Code Generation with Modality-relative Pre-training (2024.eacl-long)
Copied to clipboard
| Challenge: | Large pre-trained language models have been applied to programming language tasks with great success, often through further pre-training of a strictly-natural language model. |
| Approach: | They propose to map programming language modalities into the same embedding space by separating embeddable spaces between modality and modality-relative training objectives. |
| Outcome: | The proposed model can be adapted and represented differently depending on which modality they belong to and to the ultimate benefit of the downstream task. |
