bcms-bertic-parlasent-bcs-bi

Binary text classification model based on classla/bcms-bertic and fine-tuned on the BCS Political Sentiment dataset.

This classifier classifies text into only two categories: Negative vs. Other. For the ternary classifier (Negative, Neutral, Positive) check this model.

Fine-tuning hyperparameters

Fine-tuning was performed with simpletransformers. Beforehand a brief sweep for the optimal number of epochs was performed and the presumed best value was 9. Other arguments were kept default.


model_args = {
        "num_train_epochs": 9
        }

Performance in comparison with ternary classifier

model	average macro F1
bcms-bertic-parlasent-bcs-ter	0.7941 ± 0.0101
bcms-bertic-parlasent-bcs-bi (this model)	0.8999 ± 0.012
