When Does Non-Negative Matrix Factorization Give a Correct Decomposition into Parts?
Non-Negative Matrix Factorization Parts
2015/8/21
We interpret non-negative matrix factorization geometrically, as the
problem of finding a simplicial cone which contains a cloud of data
points and which is contained in the positive orthant.

Foulkes characters, Eulerian idempotents, and an amazing matrix。
We construct a free fermion and matrix model representation of refined BPS generating functions of D2 and D0 branes bound to a single D6 brane, in a class of toric manifolds
without compact four-cycl...

We compute the quantum effective action induced by integrating out fermions in Yang-Mills matrix models on a 4-dimensional background, expanded in powers of a gauge-invariant UV cutoff.
Matrix Factorization for an SO(2) Spinning Top and Related Problems
Matrix Factorization SO(2) Spinning Top Related Problems
2010/11/1
We study the matrix factorization problem associated with an SO(2) spinning top by using the algebro-geometric approach. We derive the explicit expressions in terms of Riemann theta functions and dis...
The Padé iterations for the matrix sign function and their reciprocals are optimal
The Padé iterations the matrix sign function reciprocals
2010/11/12
It is proved that among the rational iterations locally converging with order s>1 to the sign function, the Pad\'e iterations and their reciprocals are the unique rationals with the lowest sum of the ...
An Elementary Proof of the Polynomial Matrix Spectral Factorization Theorem
the Polynomial Matrix Spectral Factorization Theorem
2010/11/22
A very simple and short proof of the polynomial matrix spectral factorization theorem (on the unit circle as well as on the real line) is presented, which relies on elementary complex analysis and lin...
This is a short comment on the Moyal formula for deformation quantization. It is shown that the Moyal algebra of functions on the plane is canonically isomorphic to an algebra of matrices of infinite ...
