# XLS-R-300M Uyghur CV8 |
|
|
|
This model is a fine-tuned version of [facebook/wav2vec2-xls-r-300m](https://huggingface.co/facebook/wav2vec2-xls-r-300m) on the MOZILLA-FOUNDATION/COMMON_VOICE_8_0 - UG dataset. |
|
It achieves the following results on the evaluation set: |
|
- Loss: 0.2036 |
|
- WER: 0.2977 |
|
|
|
## Model description |
|
|
|
For a description of the model architecture, see [facebook/wav2vec2-xls-r-300m](https://huggingface.co/facebook/wav2vec2-xls-r-300m) |
|
|
|
The model vocabulary consists of the alphabetic characters of the [Perso-Arabic script conventionally used for the Uyghur language](https://omniglot.com/writing/uyghur.htm), with punctuation removed. |
|
|
|
## Intended uses & limitations |
|
|
|
This model is expected to be of some utility for low-fidelity use cases such as: |
|
- Draft video captions |
|
- Indexing of recorded broadcasts |
|
|
|
The model is not reliable enough to use as a substitute for live captions for accessibility purposes, and it should not be used in a manner that would infringe the privacy of any of the contributors to the Common Voice dataset nor any other speakers. |
|
|
|
## Training and evaluation data |
|
|
|
The combination of `train` and `dev` of common voice official splits were used as training data. The official `test` split was used as validation data as well as for final evaluation. |
|
|
|
## Training procedure |
|
|
|
The featurization layers of the XLS-R model are frozen while tuning a final CTC/LM layer on the Uyghur CV8 example sentences. A ramped learning rate is used with an initial warmup phase of 2000 steps, a max of 0.0001, and cooling back towards 0 for the remainder of the 18500 steps (100 epochs). |
|
|
|
### Training hyperparameters |
|
|
|
The following hyperparameters were used during training: |
|
- learning_rate: 0.0001 |
|
- train_batch_size: 8 |
|
- eval_batch_size: 8 |
|
- seed: 42 |
|
- gradient_accumulation_steps: 4 |
|
- total_train_batch_size: 32 |
|
- optimizer: Adam with betas=(0.9,0.999) and epsilon=1e-08 |
|
- lr_scheduler_type: linear |
|
- lr_scheduler_warmup_steps: 2000 |
|
- num_epochs: 100.0 |
|
- mixed_precision_training: Native AMP |
|
