LLM Model Training & Fine-tuning Expertise

I'm seeking an expert to enlighten me on the intricacies of training and fine-tuning pretrained LLM models.

My goal is to leverage these models for text generation, text classification, and question-and-answer applications. To that end, the key areas of focus during our Q&A session will be:

- Strategies to choose the right dataset for these applications.
- Techniques to optimize hyperparameters to realize optimal performance.
- Ways to counter overfitting issues to guarantee model generality.

For this project, Python will be our preferred programming language. Ideal bidders should have solid experience in Python and a deep understanding of LLM models. Your proficiency in handling overfitting, optimizing hyperparameters, and selecting appropriate datasets will be invaluable. Let's decode the mysteries of LLMs together.
