The train_mean_token_accuracy is an important metric for evaluating the performance of language models during the fine-tuning process. It provides a direct measure of how accurately the model is predicting the individual tokens in the training data, which is a key indicator of the model's learning and ability to generate accurate text.Understanding this metric can help machine learning practitioners better interpret the results of their fine-tuning experiments and make informed decisions about model architecture, hyperparameters, and training strategies.
the train_mean_token_accuracy represents the percentage of tokens in the training batch that were correctly predicted by the model.
This metric provides a direct measure of the model's ability to accurately predict the individual tokens in the training data, which is an important indicator of the model's performance during fine-tuning.
