trigrams

Trigrams are groups of three consecutive elements, such as words or characters, within a larger sequence. In language processing, they help analyze patterns by examining sets of three words or letters at a time. For example, in the phrase "machine learning models," the trigrams are "machine learning models" (if considering words) or "mac-hine-lear-ning" (if considering characters). Trigrams are useful for predicting what comes next, understanding context, or detecting language patterns. They are a fundamental building block in natural language processing, providing a balance between capturing context and maintaining manageable computational complexity.
