Transformers, explained: Understand the model behind GPT, BERT, and T5

Introduction

The field of machine learning is constantly evolving, with new inventions pushing the boundaries of what is possible. One such groundbreaking discovery that has captured the attention of the machine learning community is the transformer neural network. Transformers have revolutionized natural language processing tasks, enabling models to perform tasks like text translation, poetry writing, code generation, and more. In this article, we will delve into what transformers are, how they work, and why they have had such a significant impact on the field of machine learning.

Transformers are a type of neural network architecture that excels at processing and understanding language data, making them a versatile tool for a wide range of natural language processing tasks. By leveraging innovations such as positional encodings, attention mechanisms, and self-attention, transformers have overcome traditional challenges faced by recurrent neural networks (RNNs) in handling sequential data like text. The ability of transformers to efficiently process large amounts of data and learn complex language structures has led to the development of powerful models like BERT, GPT-3, and T5, which have demonstrated impressive capabilities in various language tasks.
