## roberta-base fine-tuned with TextAttack on the ag_news dataset

This `roberta-base` model was fine-tuned for sequence classification using TextAttack 
and the ag_news dataset loaded using the `nlp` library. The model was fine-tuned 
for 5 epochs with a batch size of 16, a learning 
rate of 5e-05, and a maximum sequence length of 128. 
Since this was a classification task, the model was trained with a cross-entropy loss function. 
The best score the model achieved on this task was 0.9469736842105263, as measured by the 
eval set accuracy, found after 4 epochs.
