Understanding the Transformer Architecture

Introduction

Since its introduction in 2017, the Transformer architecture has become the cornerstone of natural language processing. This article provides an in-depth yet accessible explanation of Transformer’s core mechanisms.

Why Do We Need Transformers?

Before Transformers, RNNs and LSTMs were the mainstream methods for sequence modeling. However, they had several limitations:

  1. Sequential Computation - Cannot be parallelized, leading to low training efficiency
  2. Long-range Dependencies - Difficulty capturing long-distance contextual information
  3. Gradient Issues - Long sequences prone to vanishing gradients

Transformers elegantly solve these problems through the self-attention mechanism.
