// MODEL OPTIMIZATION AND PROMPT SYNTAX TERM

Self-Attention

Self-attention helps a model understand how different parts of an input, like words in a sentence, relate to each other by weighing their importance.

TECHNICAL DEFINITION

Self-attention is a mechanism in transformer architectures that allows a model to weigh the importance of different elements in an input sequence relative to each other, computing a contextualized representation for each element.

BACKGROUND

A large language model (LLM) is a neural network trained on a vast amount of text for natural language processing tasks, especially language generation. LLMs can typically generate, summarize, translate and analyze text in many contexts, and are a foundational technology behind modern chatbots. Biased or inaccurate training data can make an LLM's output less reliable.
