 ## 用語集 Terminology
 
+Importance Matrix (imatrix)  
+An "imatrix" is a data structure used to optimize the quantization of a model. You create one by passing text to the [llama-imatrix](https://github.com/ggerganov/llama.cpp/tree/master/examples/imatrix) command.  
+
+重要行列（imatrix)  
+「imatrix」は、モデルの量子化を最適化するために使用されるデータ構造です。[llama-imatrix](https://github.com/ggerganov/llama.cpp/tree/master/examples/imatrix)コマンドにテキストを与えて作成します

 wiki.test.raw score  
-Perplexity Score measured using [wiki.test.raw](https://huggingface.co/datasets/Salesforce/wikitext/viewer/wikitext-103-raw-v1/test) published by Salesforce and the [llama-perplexity](https://github.com/ggerganov/llama.cpp/blob/master/examples/perplexity/README.md) command with -c 512 setting.

 ja-wiki.test.raw perplexity score  
-Perplexity score measured in the same way using Japanese data ([ja-wiki.test.raw](https://huggingface.co/dahara1/imatrix-jpn-test/blob/main/ja-wiki.test.raw)) with the same file size as wiki.test.raw, extracted from a Japanese wiki.

 Bartowski model  
 [Bartowski](https://huggingface.co/bartowski) is an individual who has quantized many models and contributed to the community. He created an imatrix from the English-only data [calibration_datav3.txt](https://gist.github.com/bartowski1182/eb213dccb3571f863da82e99418f81e8) and used it to quantize his model.
