Fine-tuning is the process of adapting a pre-trained model to perform specific tasks or cater to particular domains. It involves adjusting the model's parameters through a further round of training on task-specific or domain-specific data. While conventional fine-tuning strategies… See the full description on the dataset page: https://huggingface.co/datasets/louisbrulenaudet/bofip.
