# `rinna/nekomata-7b`
|
|
|
|
|
|
|
|
# Overview
|
|
We conduct continual pre-training of [qwen-7b](https://huggingface.co/Qwen/Qwen-7B) on **30B** tokens from a mixture of Japanese and English datasets. The continual pre-training significantly improves the model's performance on Japanese tasks. It also enjoys the following great features provided by the original Qwen model.
|
|
* The inclusive Qwen vocabulary (vocab size > 150k) enables the model to processs Japanese texts much more efficiently than the previously released [youri series](https://huggingface.co/collections/rinna/youri-7b-654053610cb8e9d8e6289efc).
|
|
* The model supports a maximum sequence length of 32768.
|
|
|
|
The name `nekomata` comes from the Japanese word [`猫又/ねこまた/Nekomata`](https://ja.wikipedia.org/wiki/%E7%8C%AB%E5%8F%88), which is a kind of Japanese mythical creature ([`妖怪/ようかい/Youkai`](https://ja.wikipedia.org/wiki/%E5%A6%96%E6%80%AA)).
|
|
|
|
|
|
* **Library**
|
|
|
|
The model was trained using code based on [EleutherAI/gpt-neox](https://github.com/EleutherAI/gpt-neox).
|
|
|
|
* **Model architecture**
|
|
|
|
A 32-layer, 4096-hidden-size transformer-based language model. Please refer to the [Qwen paper](https://arxiv.org/abs/2309.16609) for architecture details.
|
|
|
|
* **Continual pre-training**
|
|
|
|
The model was initialized with the [qwen-7b](https://huggingface.co/Qwen/Qwen-7B) model and continually trained on around **30B** tokens from a mixture of the following corpora
|
|
- [Japanese CC-100](http://data.statmt.org/cc-100/ja.txt.xz)

# Tokenization
|
|
The model uses the original Qwen tokenizer. It augments the [`cl100k` tiktoken tokenizer](https://github.com/openai/tiktoken) and has a vocabulary size of 151,936. The inclusive vocabulary helps the model to reach a better tokenization efficiency, especially for Japanese texts.
|
|
|
|
We compared the `Qwen` tokenizer (as used in `nekomata`) and the `llama-2` tokenizer (as used in `youri`) on different text collections and found that the Qwen tokenizer achieves a much better byte2token rate (i.e. the average number of tokens produced from 1 byte of text) as following. A lower byte2token rate indicates a better tokenization efficiency.

| llama-2 | 0.40 | 0.29 | 0.36 |
