Character
In Data Science, a character is a single symbol or letter that represents a piece of data. Characters are often used to represent categorical variables, such as gender or race, in statistical analysis. In programming, characters are used to represent text and are stored as a sequence of bytes. Character encoding is the process of assigning a unique number to each character in a character set, such as ASCII or Unicode, so that it can be represented in binary form. Natural Language Processing (NLP) relies heavily on character-level analysis, such as tokenization and stemming, to process and analyze text data. In machine learning, character-level models are used for tasks such as text classification and language modeling.
