The transformer model revolutionizes natural language processing (NLP) by processing entire sequences at once, leveraging techniques like self-attention mechanism, positional encodings, and multi-head attention.

This article delves into the intricacies of the transformer model, starting with its foundational mechanisms like self-attention, positional encodings, and multi-head attention. It explains how these elements enable the model to process sequences simultaneously, capturing long-range dependencies effectively. The discussion expands into the architecture of encoders and decoders, highlighting the attention mechanisms within each. Key differences between the architectures, their training modalities, and prominent models like BERT and GPT are also explored, showcasing the transformative capabilities of this technology in natural language processing and beyond.
