Separating Doubly Nonnegative and Completely
... Replacing C2n+1 with D2n+1 gives tractable DNN relaxation. • Can be shown that DNN relaxation is equivalent to “SDP+RLT” relaxation, and for n = 2 problem is equivalent to QPB [AB10]. • Constraints from Boolean Quadric Polytope (BQP) are valid for off-diagonal components of X [BL09]. For n = 3, BQP ...

... Since there is a solution with x3 = 1 and x5 = 0, we can write b3 as a linear combination of b1 , b2 , and b4 , specifically b3 = −b1 + 2b2 . Likewise, we can write b5 = b1 − 2b2 + b4 . Since the columns corresponding to the free variables are linear combinations of the pivot columns, the span of th ...

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.
