Minority Positive Sampling for Switching Points - an Anecdote for the Code-Mixing Language Modeling (2020.lrec-1)
Copied to clipboard
| Challenge: | Multilingual people code-mix using English phonetic typing and insertion of anglicisms in their native language. |
| Approach: | They propose to use minority positive sampling to selectively induce more sample to achieve better performance. |
| Outcome: | The proposed model performs better than other models, but switching points are the main challenge . |

| Challenge: | Existing scaling laws for language models are limited to a limited number of languages, but they can be applied to arbitrary number of different languages. |
| Approach: | They propose a scaling law for general-purpose decoder-only language models trained on multilingual data that shifts focus from individual languages to language families. |
| Outcome: | The proposed scaling law can be applied to models trained on multilingual data . it can be used to predict performance across multiple languages and models . |
Switch Point biased Self-Training: Re-purposing Pretrained Models for Code-Switching (2021.findings-emnlp)
Copied to clipboard
| Challenge: | Code-switching (CS) is a phenomenon of switching between multiple languages . current models cannot handle CS due to lack of annotated data and limited resources. |
| Approach: | They propose a self-training method to repurpose existing models using a switch-point bias by leveraging unannotated data to reduce the gap between the switch point performance and retain overall performance on two distinct language pairs. |
| Outcome: | The proposed model reduces the gap between the switch point performance while retaining the overall performance on two distinct language pairs. |
