BERT-base

Pretrained bidirectional encoder for russian language. The model was trained using standard MLM objective on large text corpora including open social data. See Training Details section for more information.

⚠️ This model contains only the encoder part without any pretrained head.

Developed by: deepvk
Model type: BERT
Languages: Mostly russian and small fraction of other languages
License: Apache 2.0

How to Get Started with the Model

python

from transformers import AutoTokenizer, AutoModel

tokenizer = AutoTokenizer.from_pretrained("deepvk/bert-base-uncased")
model = AutoModel.from_pretrained("deepvk/bert-base-uncased")

text = "Привет, мир!"

inputs = tokenizer(text, return_tensors='pt')
predictions = model(**inputs)

Training Details

The model was trained using the NVIDIA source code. See the pretraining documentation for details.

Training Data

250 GB of filtered texts in total. A mix of the following data: Wikipedia, Books and Social corpus.
