# `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. |
|
|
|
|
|
| Tokenizer | Japanese | English | Multilingual | |
|
| --- | --- | --- | --- | |
|
| Qwen | 0.24 | 0.27 | 0.27 | |
|
| llama-2 | 0.40 | 0.29 | 0.36 | |
