Unpacking Transformer-Based NLP

The evolution of NLP has been significantly marked by the advent of transformer-based models. These revolutionary models, which include the GPT variants, have ushered in a new era of language understanding and generation, redefining the capabilities of AI in dealing with human language. Prior to the rise of transformers, NLP predominantly relied on various other architectures, such as Recurrent Neural Networks (RNNs) and Convolutional Neural Networks (CNNs), each tailored for specific aspects of language tasks. However, transformers brought a game-changing concept to the table with their dynamic attention mechanisms and contextual word embeddings, allowing them to effectively capture contextual information and dependencies, regardless of the distance between words in a sentence.
