Learning rate scheduling
As mentioned, proper learning rate scheduling is often used for effective fine-tuning. The following code demonstrates common learning rate scheduling techniques for LLM fine-tuning, offering both linear and cosine warmup strategies to optimize training:
- First, we set up the scheduling framework with the required imports and function initialization:
from transformers import ( get_linear_schedule_with_warmup, get_cosine_schedule_with_warmup) def fine_tune_with_lr_scheduling( model, tokenizer, dataset, scheduler_type="linear", num_epochs=3 ): tokenized_dataset = dataset.map( lambda examples: tokenize_function(examples, tokenizer), batched=True)
- Next, we configure optimized training parameters with improved defaults:
