AmsterdamDocClassificationMistral200T2Epochs

As part of the Assessing Large Language Models for Document Classification project by the Municipality of Amsterdam, we fine-tune Mistral, Llama, and GEITje for document classification. The fine-tuning is performed using the AmsterdamBalancedFirst200Tokens dataset, which consists of documents truncated to the first 200 tokens. In our research, we evaluate the fine-tuning of these LLMs across one, two, and three epochs. This model is a fine-tuned version of mistralai/Mistral-7B-Instruct-v0.2 and has been fine-tuned for two epochs.

It achieves the following results on the evaluation set:

• Loss: 0.6601

Training and evaluation data

• The training data consists of 9900 documents and their labels formatted into conversations.
• The evaluation data consists of 1100 documents and their labels formatted into conversations.

Training procedure
