|
|
|
This repository provides a small-sized Japanese GPT-2 model. The model was trained using code from Github repository [rinnakk/japanese-pretrained-models](https://github.com/rinnakk/japanese-pretrained-models) by [rinna Co., Ltd.](https://corp.rinna.co.jp/) |
|
|
|
# How to use the model |
|
|
|
*NOTE:* Use `T5Tokenizer` to initiate the tokenizer. |
|
|
|
~~~~ |
|
from transformers import T5Tokenizer, GPT2LMHeadModel |
|
|
|
tokenizer = T5Tokenizer.from_pretrained("rinna/japanese-gpt2-small") |
|
tokenizer.do_lower_case = True # due to some bug of tokenizer config loading |
|
|
|
model = GPT2LMHeadModel.from_pretrained("rinna/japanese-gpt2-small") |

# Model architecture |
|
A 12-layer, 768-hidden-size transformer-based language model. |
|
|
|
# Training |
|
The model was trained on [Japanese CC-100](http://data.statmt.org/cc-100/ja.txt.xz) and [Japanese Wikipedia](https://dumps.wikimedia.org/other/cirrussearch) to optimize a traditional language modelling objective on 8\\*V100 GPUs for around 15 days. It reaches around 21 perplexity on a chosen validation set from CC-100. |
|
|
|
# Tokenization |
|
The model uses a [sentencepiece](https://github.com/google/sentencepiece)-based tokenizer, the vocabulary was trained on the Japanese Wikipedia using the official sentencepiece training script. |
