Matrix Inverse -- from Wolfram MathWorld
where is the identity matrix.Courant and Hilbert (1989, p. 10) use the notation to denote the inverse matrix.. A square matrix has an inverse iff the determinant (Lipschutz 1991, p. 45). The so-called invertible matrix theorem is major result in linear algebra which associates the existence of a matrix inverse with a number of other equivalent properties.

tf–idf - Wikipedia
The inverse document frequency is a measure of how much information the word provides, i.e., if it's common or rare across all documents. It is the logarithmically scaled inverse fraction of the documents that contain the word (obtained by dividing the total number of documents by the number of documents containing the term, and then taking the logarithm of that quotient):
