What does IDF mean?
Inverse Document Frequency (IDF) is a measure of the importance of a word within a collection of documents, such as a corpus or a database. It is a numerical representation of how unique or important a word or a term is within a collection of documents.
IDF is a component of the Term Frequency-Inverse Document Frequency (TF-IDF) weighting scheme, which is widely used in various natural language processing tasks, including document retrieval, text classification, and information retrieval systems.
