Welcome to the Transformer Basics tutorial! 🌟 This guide will walk you through the fundamental concepts of the Transformer architecture, a revolutionary model in natural language processing (NLP).
What is a Transformer?
The Transformer is a deep learning model introduced in the paper "Attention is All You Need" by Google Research. Unlike traditional RNNs or CNNs, it relies entirely on self-attention mechanisms to process input sequences, enabling parallel computation and better handling of long-range dependencies.
Key Components
Self-Attention Mechanism 🧠
Allows the model to weigh the importance of different words in a sentence dynamically.Positional Encoding 🗺️
Adds information about the position of each word in the sequence.Feed-Forward Neural Networks ⚙️
Each position independently processes the data through a fully connected layer.Encoder-Decoder Structure 🔗
The model consists of multiple encoder and decoder layers, with attention bridges between them.
Why Use Transformers?
- Parallel Processing: Unlike sequential models, Transformers can compute all parts of the input simultaneously.
- Scalability: Efficiently handles long sequences with self-attention.
- Versatility: Applied to tasks like machine translation, text summarization, and more.
