Definition
A tetragram is a sequence of four adjacent elements taken from a string of text or other data. These elements, similar to bigrams and trigrams, can be letters, numbers, or words, depending on the specific application. ➕➕ Tetragrams are used in fields like cryptography, data compression, and even music analysis to identify and analyze patterns. They offer a more detailed view than bigrams and trigrams by examining longer sequences. For example, "this is an example" is a tetragram. They provide richer insights into the structure and relationships within a data set.
