How to Get Started with the Model

from transformers import AutoTokenizer, AutoModel

tokenizer = AutoTokenizer.from_pretrained("deepvk/deberta-v1-base")
model = AutoModel.from_pretrained("deepvk/deberta-v1-base")

text = "Привет, мир!"

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

Training Details

Training Data

400 GB of filtered and deduplicated texts in total. A mix of the following data: Wikipedia, Books, Twitter comments, Pikabu, Proza.ru, Film subtitles, News websites, and Social corpus.

Deduplication procedure

1. Calculate shingles with size of 5
2. Calculate MinHash with 100 seeds → for every sample (text) have a hash of size 100
3. Split every hash into 10 buckets → every bucket, which contains (100 / 10) = 10 numbers, get hashed into 1 hash → we have 10 hashes for every sample
4. For each bucket find duplicates: find samples which have the same hash → calculate pair-wise jaccard similarity → if the similarity is >0.7 than it's a duplicate
5. Gather duplicates from all the buckets and filter

Training Hyperparameters

The model was trained on a machine with 8xA100 for approximately 30 days.

Evaluation

We evaluated the model on Russian Super Glue dev set. The best result in each task is marked in bold. All models have the same size except the distilled version of DeBERTa.
