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.

Analyzing work functions and the IO variables they
need is an important component of designing and evaluating
complex systems. We develop a biclustering method for jointly
grouping work functions a...

2011/5/9
A novel method of Fisher’s linear discriminant (FLD) in the residual space is put forward for
the representation of face images for face recognition, which is robust to the slight local
feature chan...
