irony_pt_Portugal

This model is a fine-tuned version of roberta-base on part of the MultiPICo dataset. It achieves the following results on the evaluation set:

• Loss: 0.0033
• Accuracy: 0.5693
• Precision: 0.4453
• Recall: 0.7483
• F1: 0.5584

Model description

The model is trained considering the annotation of annotators from Portuguese only, on instances in Portuguese (PT and BZ linguistic varieties). The annotations from these annotators are aggregated using majority voting and then used to train the model.

Training and evaluation data

The model has been trained on the annotation from annotators from Portugal from the MultiPICo dataset (instances in Portuguese). The data has been randomly split into a train and a validation set.

Training procedure

Training hyperparameters
