L1-norm Principal-Component Analysis of Complex Data
Nicholas Tsagkarakis, Panos P. Markopoulos, Dimitris A. Pados
L1-norm Principal-Component Analysis (L1-PCA) of real-valued data has attracted significant research interest over the past decade. However, L1-PCA of complex-valued data remains t…
Efficient L1-Norm Principal-Component Analysis via Bit Flipping
Panos P. Markopoulos, Sandipan Kundu, Shubham Chamadia +1
It was shown recently that the L1-norm principal components (L1-PCs) of a real-valued data matrix ( data samples of dimensions) ca…
Optimal Algorithms for -subspace Signal Processing
Panos P. Markopoulos, George N. Karystinos, Dimitris A. Pados
We describe ways to define and calculate -norm signal subspaces which are less sensitive to outlying data than -calculated subspaces. We start with the computation of the…
