chunk_content: P-tuning for sequence classification
  	
  It is challenging to finetune large language models for downstream tasks because they have so many parameters. To work around this, you can use prompts to steer the model toward a particular downstream task without fully finetuning a model. Typically, these prompts are handcrafted, which may be impractical because you need very large validation sets to find the best prompts. P-tuning is a method for automa
