Attention Mechanisms

Attention mechanisms play a crucial role in sequence modeling by allowing dependencies to be modeled without considering their distance in input or output sequences. They enhance the performance of models by capturing relevant information effectively.

Overview

Attention mechanisms are a crucial component of modern machine learning, particularly in natural language processing and computer vision. They enable models to focus on relevant parts of the input data, improving their performance and understanding of context. By allowing models to weigh the importa...

Key Terms

Attention
A mechanism that allows models to focus on specific parts of the input data.

Example: In translation, attention helps the model focus on relevant words.

Self-Attention
A type of attention where the input sequence is compared to itself.

Example: Used in transformers to weigh words in a sentence.

Multi-Head Attention
An extension of self-attention that allows multiple attention mechanisms to run in parallel.

Example: Enables the model to capture different aspects of the input.

Transformer
A model architecture that uses attention mechanisms to process data.

Example: BERT and GPT are popular transformer models.

Contextual Representation
A representation of data that considers the context in which it appears.

Example: Word embeddings that change meaning based on surrounding words.

Neural Network
A computational model inspired by the human brain, used in machine learning.

Example: Used for tasks like image recognition and language processing.
