| # mBERT swedish distilled base model (cased) | |
| This model is a distilled version of [mBERT](https://huggingface.co/bert-base-multilingual-cased). It was distilled using Swedish data, the 2010-2015 portion of the [Swedish Culturomics Gigaword Corpus](https://spraakbanken.gu.se/en/resources/gigaword). The code for the distillation process can be found [here](https://github.com/AddedK/swedish-mbert-distillation/blob/main/azureML/pretrain_distillation.py). This was done as part of my Master's Thesis: *Task-agnostic knowledge distillation of mBERT to Swedish*. | |
| ## Model description | |
| This is a 6-layer version of mBERT, having been distilled using the [LightMBERT](https://arxiv.org/abs/2103.06418) distillation method, but without freezing the embedding layer. | |
| ## Intended uses & limitations | |
| You can use the raw model for either masked language modeling or next sentence prediction, but it's mostly intended to | |
| be fine-tuned on a downstream task. | |
| ## Training data | |
| The data used for distillation was the 2010-2015 portion of the [Swedish Culturomics Gigaword Corpus](https://spraakbanken.gu.se/en/resources/gigaword). | |
| The tokenized data had a file size of approximately 9 GB. | |
| ## Evaluation results | |
| When evaluated on the [SUCX 3.0 ](https://huggingface.co/datasets/KBLab/sucx3_ner) dataset, it achieved an average F1 score of 0.859 which is competitive with the score mBERT obtained, 0.866. | |
| When evaluated on the [English WikiANN](https://huggingface.co/datasets/wikiann) dataset, it achieved an average F1 score of 0.826 which is competitive with the score mBERT obtained, 0.849. | |
| Additional results and comparisons are presented in my Master's Thesis | |
