Fourier analysis on finite groups and Schur orthogonality
... Intuitively, the discrete Fourier transform picks out the components of f with frequencies less than about n2 ; it makes sense that with only n sample points, one can only read information about that range of frequencies. Note however that as n → ∞ one will recover the classical Fourier series, so t ...

11 Linear dependence and independence
... are linearly dependent because 2x1 + x2 − x3 = 0. 2. Any set containing the vector 0 is linearly dependent, because for any c 6= 0, c0 = 0. 3. In the definition, we require that not all of the scalars c1 , . . . , cn are 0. The reason for this is that otherwise, any set of vectors would be linearly ...

Max algebra and the linear assignment problem
... This theorem suggests that assignments play a role with respect to the unique solubility of a linear equation system. And indeed, if a linear equation system with a real n × n coefficient matrix is soluble and the solution is unique, then the linear assignment problem with cost matrix A has only one ...

Non-negativity and sparsity together are desirable properties to have for basis decomposition techniques, but a statistical underpinning for such techniques is just as important. There are two main contr ...

Non-negative matrix factorization

NMF redirects here. For the bridge convention, see new minor forcing.Non-negative matrix factorization (NMF), also non-negative matrix approximation is a group of algorithms in multivariate analysis and linear algebra where a matrix V is factorized into (usually) two matrices W and H, with the property that all three matrices have no negative elements. This non-negativity makes the resulting matrices easier to inspect. Also, in applications such as processing of audio spectrograms non-negativity is inherent to the data being considered. Since the problem is not exactly solvable in general, it is commonly approximated numerically.NMF finds applications in such fields as computer vision, document clustering, chemometrics, audio signal processing and recommender systems.
