Correlation matrices for 87-PN time-slice vectors
Neural Tensor Networks with Diagonal Slice Matrices
... Here, since x 1 , x 2 ∈ R n , W 1 , W 2 ∈ R k×n , this linear mapping is a transformation from R 2n to R k . Linear mapping, which is a standard com- ponent of NNs, has been applied successfully in many tasks. However, ...
