| Challenge: | a prerequisite for building large-scale generative models for other languages is access to large amounts of high-quality text data and powerful computational resources. |
| Approach: | They present a 3.5 billion parameter autoregressive language model, trained on a 100 GB Swedish corpus. |
| Outcome: | The proposed model performs well on a 100 GB Swedish corpus and is competent in comparison with existing models of similar size. |

| Challenge: | In this paper, we present a multi-task benchmark for Swedish language models . we address methodological challenges, such as mitigating the Anglocentric bias when creating datasets for a less-resourced language . |
| Approach: | They propose a multi-task NLP benchmark for Swedish language models . they propose to use superlim to evaluate Swedish language model performance . |
| Outcome: | The proposed benchmark does not approach ceiling performance on any of the tasks, suggesting it is difficult to implement. |
Fine-Grained Controllable Text Generation Using Non-Residual Prompting (2022.acl-long)
Copied to clipboard
| Challenge: | Existing approaches to control the text generation process are not expressive enough. |
| Approach: | They propose an encoder-decoder architecture that enables intermediate text prompts at arbitrary time steps. |
| Outcome: | The proposed architecture is expressive and versatile on multiple experimental settings. |

| Challenge: | a growing interest in building and applying large language models for languages other than English is fueling interest in developing LLMs for smaller languages. |
| Approach: | They describe the development process for the first native large generative language model for the North Germanic languages, GPT-SW3. |
| Outcome: | The proposed model is based on the generative language model for the North Germanic languages . it is a first-generation model with a high-quality data set and a low cost of implementation . |
