Introduction

The field of NLP was revolutionized in the year 2018 with the introduction of BERT and its Transformer companions (RoBerta, XLM, etc.). These novel transformer-based neural network architectures and innovative training methods on natural language data introduced the concept of transfer learning to NLP problems. Much like how transfer learning has already transformed the Computer Vision domain, the arrival of transformer models brought about a similar paradigm shift in NLP.

Companies like Google and Facebook trained their neural networks on extensive amounts of language data to understand the nuances of language, subsequently generating powerful language models. These models were then fine-tuned to specific datasets to achieve state-of-the-art results for particular problem statements. Furthermore, these trained models were released to the open-source community, allowing members to tailor them to their needs.

Hugging Face simplifies the process of accessing and fine-tuning these models with its Python package, Transformers.

Motivation

Despite these remarkable advancements, applying these solutions to real-world business problems remains a challenge due to the specialized knowledge required to understand and implement these methodologies effectively. This tutorial series demonstrates how users can leverage technologies along with other Python tools to fine-tune language models for specific tasks.

Before diving into the tutorials, I want to express my gratitude to various groups for their incredible work that has made these notebooks and tutorials possible:

• Hugging Face Team
• Abhishek Thakur for his amazing Youtube videos
