WebIn machine learning, the word tensor informally refers to two different concepts that organize and represent data. Data may be organized in an M-way array that is informally referred to as a "data tensor". However, a tensor is a multilinear mapping over a set of domain vector spaces to a range vector space. Observations, such as images, movies, …
