Notebooks

Here are some of the notebooks included in the notebooks directory:

Part I - Introduction to Large Language Models

• 2_semantic_search.ipynb: An introduction to semantic search using OpenAI and open source models.
• 3_prompt_engineering.ipynb: A guide to effective prompt engineering for instruction aligned LLMs.

Part II - Getting the Most Out of LLMs

• 4_fine_tuned_classification.ipynb: Learn how to perform text classification through fine-tuning OpenAI models
  • Check out UPDATED 4_fine_tuned_classification_sentiment.ipynb for the updated version of the previous notebook because OpenAI made a new Fine-tuning API and Amazon revoked access to the dataset I used (always keeping me on my toes, thanks everyone)
• 5_adv_prompt_engineering.ipynb: Advanced techniques for prompt engineering including k-shot, semantic k-shot, chain of thought prompting, chaining, and building a retrieval augmented generating (RAG) enabled chatbot with GPT-4.
• 5_VQA.ipynb: Introduction to prompt chaining and Visual Question Answering (VQA) with open source LLMs
• 6_recommendation_engine.ipynb: Building a recommendation engine using custom fine-tuned LLMs
  • Check out this colab notebook here for the most recent update of this case study with more graphs and more compute! https://colab.research.google.com/drive/1JfxyxdGCDjYeO52Bk1JzW4Af94xndTws?usp=sharing

Part III - Advanced LLM Usage

• 7_using_our_vqa.ipynb: A notebook to use the VQA system we built in the previous notebook.
• 7_rl_flan_t5_summaries.ipynb: Using Reinforcement Learning (RL) to produce more neutral and grammatically correct summaries with the FLAN-T5 model.
• 8_latex_gpt2.ipynb: Fine-tuning GPT-2 to generate LaTeX formulas
• 8_anime_category_classification_model_freezing.ipynb: Fine-tuning a BERT model to classify anime categories with a comparison between freezing model layers and keeping the model unfrozen.
• 8_optimizing_fine_tuning.ipynb: Best practices for optimizing fine-tuning of transformer models - dynamic padding, gradient accumulation, mixed precision, and more.
• 8_sawyer_1_instruction_ft.ipynb: Fine-tuning the instruction model for the SAWYER bot.
• 8_sawyer_2_train_reward_model.ipynb: Training a reward model for the SAWYER bot from human preferences.
• 8_sawyer_3_rl.ipynb: Using Reinforcement Learning from Human Feedback (RLHF) to further align the SAWYER bot
• 8_sawyer_4_use_sawyer.ipynb: Using our SAWYER bot
• 9_distillation.ipynb: An exploration of knowledge distillation techniques for transformer models.

We will continue to add more notebooks exploring topics like fine-tuning, advanced prompt engineering, combining transformers, and various use-cases. Stay tuned!

How to Use
