Transformers have become one of the cornerstones in the landscape of Machine Learning. Initially designed for Natural Language Processing (NLP), their versatility has seen them extend into realms such as computer vision and reinforcement learning. This blog celebrates that leap in evolution, providing you with a comprehensive study guide to embark on your journey of mastering transformers.

What Are Transformers?

At their core, transformers are a type of model architecture primarily designed to process sequential data, such as text. Central to their operation is the attention mechanism, which allows the model to focus on relevant parts of the input data and weigh their importance accordingly. You can think of transformers as a chef who is preparing a dish and must select the best ingredients while ignoring those that don’t add value.
