yacis-electra-small

This is ELECTRA Small model for Japanese pretrained on 354 million sentences / 5.6 billion words of YACIS blog corpus.

The corpus was tokenized for pretraining with MeCab. Subword tokenization was done with WordPiece.

Model architecture

This model uses ELECTRA Small model settings, 12 layers, 128 dimensions of hidden states, and 12 attention heads.

Vocabulary size was set to 32,000 tokens.

Training data and libraries

YACIS-ELECTRA is trained on the whole of YACIS blog corpus, which is a Japanese blog corpus containing 5.6 billion words in 354 million sentences.

The corpus was originally split into sentences using custom rules, and each sentence was tokenized using MeCab. Subword tokenization for pretraining was done with WordPiece.

We used original ELECTRA repository for pretraining. The pretrainig process took 7 days and 6 hours under the following environment: CPU: Intel Core i9-7920X, RAM: 132 GB, GPU: GeForce GTX 1080 Ti x1.
