Least squares regression - Fisher College of Business
... This is a quick tutorial to get you up to speed on least squares regression in case you have not seen it before or need a refresher. You will see more of it in other business classes but this explanation should work for our purposes. The idea of least squares regression is to find a best solution to ...

A Complete Characterization of a Family of Solutions to a
... For the full characterization of the set of solutions to Equation (1), initially the problem is looked at from a geometrical point of view (cf., Campbell and Atchley, 1981). It is assumed that the number of samples N is smaller than or equal to the feature dimensionality n. In the undersampled case, ...

... Definition: Let A and B be two matrices. These matrices are the same, that is, A = B if they have the same number of rows and columns, and every element at each position in A equals the element at corresponding position in B. * This is not trivial if elements are real numbers subject to digital appr ...

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.
