A MacBERTh model fine-tuned on SQuAD_v2. Hopefully, this will allow the model to perform well on QA tasks on historical texts. Finetune parameters:
training_args = TrainingArguments(
output_dir="./results",
evaluation_strategy="epoch",
learning_rate=3e-5,
per_device_train_batch_size=64,
per_device_eval_batch_size=64,
num_train_epochs=2,
weight_decay=0.01,
lr_scheduler_type=SchedulerType.LINEAR,
warmup_ratio=0.2
)
