What is self-attention?

A mechanism in neural networks that allows the model to focus on specific parts of the input data

Self-attention is a way for a neural network to weigh the importance of different parts of the input data, such as words in a sentence, and focus on the most relevant ones when making predictions

Self-attention is like a spotlight that shines on specific words or phrases in a sentence, highlighting their importance and helping the model understand the context better

For example, in a language translation task, self-attention can help the model focus on the words 'bank' and 'river' when translating the sentence 'I went to the bank by the river', to ensure that the correct meaning is conveyed

Self-attention is commonly used in natural language processing tasks, such as language translation, question answering, and text summarization, to improve the model's ability to understand the input data

One common misconception is that self-attention is only used for natural language processing tasks, when in fact it can be applied to other areas, such as computer vision and speech recognition

Self-attention was first introduced in the paper 'Attention Is All You Need' by Vaswani et al. in 2017, and has since become a widely used technique in the field of natural language processing
