# RoBERTa Turkish medium WordPiece 66k (uncased)
|
12 |
-
|
13 |
-
Pretrained model on Turkish language using a masked language modeling (MLM) objective. The model is uncased.
|
14 |
-
The pretrained corpus is OSCAR's Turkish split, but it is further filtered and cleaned.
|
15 |
-
|
16 |
-
Model architecture is similar to bert-medium (8 layers, 8 heads, and 512 hidden size). Tokenization algorithm is WordPiece. Vocabulary size is 66.7k.
