Fine-Tuning Large Language Models: Unlocking Their Full Potential

Fine-Tuning Large Language Models

• Foundational models are fundamental models that serve as building blocks for more complex models and applications in artificial intelligence (AI) and machine learning (ML).
• Large language models (LLMs) like BERT and GPT-4 are examples of foundational models that learn from and generalize across a large amount of data, enabling them to capture underlying patterns and relationships.
• To manage LLMs for highly critical tasks and handling sensitive data, fine-tuning can be used. Techniques like reinforcement learning and prompt engineering are available, but retrieval augmentation (RAG) techniques like search APIs, vector databases and parameter-efficient fine-tuning (PEFT) are discussed here.
• RAG techniques help incorporate external knowledge into an LLM to improve accuracy and data leakage management, allowing for context enrichment, fact verification and answer generation.
• Search examples and SerpApi Google Search API can automate data retrieval, save time and resources and improve accuracy and consistency. Vector databases can provide precise and targeted knowledge retrieval and enhance the efficiency and effectiveness of your knowledge management processes.
• PEFT methods offer a cost-efficient and faster alternative to fine-tuning by adapting pre-trained models to downstream applications, only fine-tuning a small number of extra model parameters.
• Integration of these techniques can empower executives and technical leaders.

In artificial intelligence and machine learning, a foundational model refers to a fundamental or base model that is the building block for more complex models and applications. It typically encompasses a broad range of knowledge, understanding and capabilities that form the basis for more specialized models or tasks. Foundational models learn from and generalize across a large amount of data, enabling them to capture underlying patterns and relationships. Stanford Institute for Human-Centered Artificial Intelligence popularized the term “foundation model.” We called these models large language models, or LLMs for short.

Examples of foundational models like BERT, and variants of GPT, like GPT-3, GPT-3.5, GPT-4 and so on, are models that have been pre-trained on a massive amount of text data and can generate human-like responses to prompts, answer questions and perform various natural language processing tasks. They serve as a foundation for developing more focused language models or applications.

Texts generated by foundational or LLMs, like ChatGPT, are fluent, coherent and informative. They can generalize from the vast world knowledge encapsulated within them, which contributes to their impressive capabilities. However, due to the imperfect knowledge encoding process, LLMs tend to hallucinate. Often, this can be problematic when deployed for highly critical tasks. Protecting data in regulated organizations is crucial. Using a foundational model directly might not be ideal in situations involving sensitive data, as it might generate text based on its pre-trained data. Adapting the AI to your data and maintaining privacy can be achieved by fine-tuning it with your data.

Fine-tuning can help manage LLMs for highly critical tasks and sensitive data. By fine-tuning these models, we can make them more effective at analyzing sentiment, answering questions and identifying text. Several techniques are available for fine-tuning foundational models, including reinforcement learning and prompt engineering. In this post, however, we’ll discuss some new forms of retrieval augmentation (RAG.) RAG techniques incorporate external knowledge into an LLM to improve accuracy and data leakage. The retrieval process queries the external knowledge source based on the input prompt or query. A RAG technique can identify the source of trained information and preserve data lineage (where it came from) over simple search and retrieval against foundation models. Pre-trained foundational models do not keep this information. You can use the retrieved data in a variety of ways, including:

Context enrichment: The retrieved knowledge can provide additional context or relevant facts to help the model generate more informed responses.

Fact verification: The retrieved information can be used to verify or validate statements made by the model, ensuring the accuracy of the generated output.

Answer generation: In question-answering tasks, the retrieved information can provide potential answers or evidence to support the model’s response.

Retrieval augmentation combines the strengths of pre-trained language models, which are highly effective at language understanding, with comprehensive external information. A broader knowledge base than pre-training can improve the model’s quality, accuracy and relevance.

Use the latest knowledge management techniques to stay ahead of the curve.

Overview of Using Parameter-Efficient Fine-Tuning (PEFT) with LLMs

PEFT Methods: PEFT methods enable efficient adaptation of pre-trained language models to various downstream applications without fine-tuning all the model’s parameters. They only fine-tune a small number of extra model parameters, significantly reducing computational and storage costs.

Benefits of PEFT:

• Fine-tuning with a small amount of data
• Improved generalization to other scenarios
• Particularly useful for fine-tuning large language models and models like StyleGAN and AI art models
• Resulting checkpoints are considerably smaller, making it easier to manage and store the fine-tuned models

PEFT and LoRa: PEFT employs various techniques, including Low-Rank Adaptation (LoRa), to efficiently fine-tune large language models. LoRa focuses on adding extra weights to the model while freezing most of the pre-trained network’s parameters. This approach helps prevent catastrophic forgetting during the fine-tuning process.

Hugging Face PEFT Library: Hugging Face has released a library that integrates PEFT with the transformers and accelerates libraries. This integration allows users to easily fine-tune pre-trained models from various companies using PEFT.

PEFT Framework: The provided context includes LLM-Adapters, an easy-to-use framework that integrates various adapters into LLMs and can execute adapter-based PEFT methods for different tasks. The framework includes state-of-the-art open-access LLMs such as LLaMA, BLOOM, OPT and GPT-J, as well as widely used adapters such as Series.

Resources: The given context provides a link to the PEFT documentation on huggingface.co/docs/peft, which can provide more detailed information about the PEFT methods and their implementation.

Parameter-Efficient Fine-Tuning (PEFT) is used to fine-tune large pre-trained language models with fewer parameters. It aims to achieve comparable performance while significantly reducing the computational resources and time required for training. The traditional approach to fine-tuning involves updating all the parameters of a pre-trained language model using a large amount of task-specific data. However, this process can be computationally expensive and time-consuming. PEFT addresses this challenge by selectively updating a subset of the model’s parameters during fine-tuning. Instead of updating all parameters, PEFT focuses on a smaller set of key parameters most relevant to the downstream task. The key idea behind PEFT is to identify the critical parameters by leveraging “importance estimation.” A parameter’s importance is determined by its impact on the model. In fine-tuning the model, parameters that have a greater impact on performance are prioritized. Once the essential parameters are identified, PEFT performs fine-tuning by updating only those parameters while keeping the remaining parameters fixed. This reduces the computational cost and training time significantly compared to full fine-tuning. PERT allows for faster experimentation and deployment of fine-tuned language models, making it a valuable technique for practical applications. It’s worth noting that PEFT is a relatively new technique, and research in this area is ongoing. Different variations and refinements of PEFT may exist, and the specific implementation details may vary depending on the research or application context.
