Improving Language Understanding by Generative Pre-Training

Overview

This paper introduces the Generative Pre-Training (GPT) model, demonstrating that a generative language model can be fine-tuned to perform various natural language understanding tasks. It uses a semi-supervised approach, first pre-training on a large unlabeled text corpus with a language modeling objective, then supervised fine-tuning on downstream tasks.

Use cases

• Fine-tuning a pre-trained language model for text classification
• Adapting GPT for natural language inference benchmarks
• Using GPT as a baseline transformer for generative language tasks

Pros

• Pioneered the pre-train then fine-tune paradigm for NLP tasks
• Demonstrated strong zero-shot and transfer learning capabilities
• Open access paper with detailed methodology for reproducibility

Cons

• Model architecture is relatively small by modern standards (117M parameters)
• Requires significant computational resources for pre-training from scratch
• Outperformed by larger subsequent models and newer training techniques
