Fine-tunen voor reviewclassificatie

Je project gaat verder en je wilt de reviews nu classificeren als positief, neutraal of negatief. Je gebruikt een gefine-tuned model om de reviews automatisch te categoriseren.

De klassen TrainingArguments en Trainer zijn geïmporteerd uit transformers. De training_args, model en tokenized_datasets zijn ook al vooraf geïmporteerd.
