Natural Language Processing with Flair

By: Tadej Magajna

Overview of this book

Flair is an easy-to-understand natural language processing (NLP) framework designed to facilitate training and distribution of state-of-the-art NLP models for named entity recognition, part-of-speech tagging, and text classification. Flair is also a text embedding library for combining different types of embeddings, such as document embeddings, Transformer embeddings, and the proposed Flair embeddings. Natural Language Processing with Flair takes a hands-on approach to explaining and solving real-world NLP problems. You'll begin by installing Flair and learning about the basic NLP concepts and terminology. You will explore Flair's extensive features, such as sequence tagging, text classification, and word embeddings, through practical exercises. As you advance, you will train your own sequence labeling and text classification models and learn how to use hyperparameter tuning in order to choose the right training parameters. You will learn about the idea behind one-shot and few-shot learning through a novel text classification technique TARS. Finally, you will solve several real-world NLP problems through hands-on exercises, as well as learn how to deploy Flair models to production. By the end of this Flair book, you'll have developed a thorough understanding of typical NLP problems and you’ll be able to solve them with Flair.

Using managed services for deploying and using Flair models

Unlike self-serving, where most aspects of the ML life cycle need to be taken care of manually, the managed and fully managed ML services sell the idea of a complete out-of-the box ML as a service solution.

Most of these services offer guarantees about service availability (what percentage of the time the service is guaranteed to be working) and scalability (the ability to scale without having to refactor the entire infrastructure every time the user base grows). Some services also offer management of the entire ML life cycle called Machine Learning Model Operationalization (MLOps) management. But some managed services may have trouble providing support for all the features and tasks Flair is capable of solving. This applies to almost all popular ML-as-a-service solutions, with one exception – the Hugging Face Models Hub.
