Model Card for Model ID

This is a flan-t5-base model finetuned using QLoRA (PEFT) on dialogSum dataset : https://huggingface.co/datasets/knkarthick/dialogsum

Model Details

Training Details:

This is just a basic fine tuned model using below training args and params

lora_config = LoraConfig( r=16, lora_alpha=32, target_modules=['q','k','v','o'], lora_dropout=.05, bias='none', task_type=TaskType.SEQ_2_SEQ_LM #flan-t5 )

output_dir = f'/kaggle/working/qlora-peft-flant5-base-dialogue-summary-training-{str(int(time.time()))}'

peft_training_args_4bit = TrainingArguments( output_dir=output_dir, auto_find_batch_size=True, learning_rate=1e-3, # Higher learning rate than full fine-tuning. num_train_epochs=200, logging_steps=10, max_steps=200
)

peft_trainer_4bit = Trainer( model=peft_model_4bit, args=peft_training_args_4bit, train_dataset=tokenized_dataset_cleaned["train"], eval_dataset=tokenized_dataset_cleaned['validation'] )
