These models can often be adapted to domain-specific tasks with relatively limited training data by using transfer learning techniques to fine-tune pre-trained large language models (see, e.g.,).
Fine-Tuning: Adjusting the pre-trained model on the limited domain-specific data.
Feature Extraction: Using the pre-trained model to extract features and train a smaller model on those features.
Domain Adaptation Techniques: Domain adaptation techniques apply things like domain-specific pre-training or multi-task learning to specialize the model even more.
Regularization: add techniques on top of architecture such as dropout, weight decay, and early stopping to avoid overfitting.
Data Augmentation: Creating more fake data to improve training
