Transformers are the superpower behind large language models (LLMs) like ChatGPT, Bard, and LLAMA. Transformers in Action gives you the insights, practical techniques, and extensive code samples you need to adapt pretrained transformer models to new and exciting tasks.
Inside Transformers in Action youll learn
How transformers and LLMs work
Adapt HuggingFace models to new tasks
Automate hyperparameter search with Ray Tune and Optuna
Optimize LLM model performance
Advanced prompting and zero/few-shot learning
Text generation with reinforcement learning
Responsible LLMs
Technically speaking, a Transformer is a neural network model that finds relationships in sequences of words or other data by using a mathematical technique called attention in its encoder/decoder components. This setup allows a transformer model to learn context and meaning from even long sequences of text, thus creating much more natural responses and predictions. Understanding the transformers architecture is the key to unlocking the power of LLMs for your own AI applications.
This comprehensive guide takes you from the origins of transformers all the way to fine-tuning an LLM for your own projects. Author Nicole Knigstein demonstrates the vital mathematical and theoretical background of the transformer architecture practically through executable Jupyter notebooks, illuminating how this amazing technology works in action.
about the book
Transformers in Action adds the revolutionary transformers architecture to your AI toolkit. Youll dive into the essential details of the models architecture, with all complex concepts explained through easy-to-understand examples and clever analogiesfrom sock sorting to skiing! Even complex foundational concepts start with practical applications, so you never have to struggle with abstract theory. The book includes an extensive code repository that lets you instantly start playing and exploring different LLMs.
In this interesting guide, youll start by applying transformers to fundamental NLP tasks like text summarization and text classification. Then, youll push transformers farther with tasks like generating text, honing text generation with reinforcement learning, developing multimodal models, and few-shot learning. Youll discover one-of-a-kind advice on prompt engineering, as well as proven-and-tested methods for optimizing and tuning large language models. Plus, youll find unique coverage of AI ethics such as mitigating bias and responsible usage.
