# RoBERTa Turkish medium Character-level (uncased) |
|
|
|
Pretrained model on Turkish language using a masked language modeling (MLM) objective. The model is uncased. |
|
The pretrained corpus is OSCAR's Turkish split, but it is further filtered and cleaned. |
|
|
|
Model architecture is similar to bert-medium (8 layers, 8 heads, and 512 hidden size). Tokenization algorithm is Character-level, which means that text is split by individual characters. Vocabulary size is 384. |

## Note that this model does not include a tokenizer file, because it uses ByT5Tokenizer. The following code can be used for model loading and tokenization, example max length(1024) can be changed: |
|
``` |
|
model = AutoModel.from_pretrained([model_path]) |
|
#for sequence classification: |
|
#model = AutoModelForSequenceClassification.from_pretrained([model_path], num_labels=[num_classes]) |
|
|
|
tokenizer = ByT5Tokenizer.from_pretrained("google/byt5-small") |
|
tokenizer.mask_token = tokenizer.special_tokens_map_extended['additional_special_tokens'][0] |
|
tokenizer.cls_token = tokenizer.special_tokens_map_extended['additional_special_tokens'][1] |
|
tokenizer.bos_token = tokenizer.special_tokens_map_extended['additional_special_tokens'][1] |
|
tokenizer.sep_token = tokenizer.special_tokens_map_extended['additional_special_tokens'][2] |
|
tokenizer.eos_token = tokenizer.special_tokens_map_extended['additional_special_tokens'][2] |
|
tokenizer.pad_token = tokenizer.special_tokens_map_extended['additional_special_tokens'][3] |
|
tokenizer.unk_token = tokenizer.special_tokens_map_extended['additional_special_tokens'][3] |
|
tokenizer.model_max_length = 1024 |
|
``` |
