Definition
This concept focuses on the manipulation of text where the fundamental unit of computation is a single character. It is often used in tasks requiring fine-grained text analysis, such as spell checking, OCR correction, or generating text at the byte/pixel level in older models. While modern LLMs typically operate on tokens (subwords), character-level approaches remain relevant for low-resource languages, cryptography, and specific generative tasks where token boundaries may obscure meaningful patterns.
Summary
Character computing involves processing, generating, or analyzing text at the individual character level rather than word or sentence level.
