distilrubert-tiny-cased-conversational-5k

Conversational DistilRuBERT-tiny-5k (Russian, cased, 3‑layers, 264‑hidden, 12‑heads, 3.6M parameters, 5k vocab) was trained on OpenSubtitles[1], Dirty, Pikabu, and a Social Media segment of Taiga corpus[2] (as Conversational RuBERT).

Our DistilRuBERT-tiny-5k is highly inspired by [3], [4] and architecture is very close to [5]. Namely, we use

  • MLM loss (between token labels and student output distribution)
  • KL loss (between averaged student and teacher hidden states)

The key feature is:

  • reduced vocabulary size (5K vs 30K in tiny vs. 100K in base and small)

Here is comparison between teacher model (Conversational RuBERT) and other distilled models.

DistilRuBERT-tiny was trained for about 100 hrs. on 7 nVIDIA Tesla P100-SXM2.0 16Gb.

We used PyTorchBenchmark from transformers to evaluate model's performance and compare it with other pre-trained language models for Russian. All tests were performed on NVIDIA GeForce GTX 1080 Ti and Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz

To evaluate model quality, we fine-tuned DistilRuBERT-tiny-5k on classification (RuSentiment, ParaPhraser), NER and question answering data sets for Russian. The results could be found in the paper Table 4 as well as performance benchmarks and training details.
