Tikhonov regularization and randomized GSVD

Y Wei, P Xie, L Zhang - SIAM Journal on Matrix Analysis and Applications, 2016 - SIAM
The generalized singular value decomposition (GSVD) is one of the essential tools in
numerical linear algebra. This paper proposes a regularization method, combining Tikhonov …

Formation of similarity-reflecting binary vectors with random binary projections

DA Rachkovskij - Cybernetics and Systems Analysis, 2015 - Springer
We propose a transformation of real input vectors to output binary vectors by projection
using a binary random matrix with elements {0, 1} and thresholding. We investigate the rate …

Building a world model with structure-sensitive sparse binary distributed representations

DA Rachkovskij, EM Kussul, TN Baidyk - Biologically Inspired Cognitive …, 2013 - Elsevier
We present a new cognitive architecture named Associative-Projective Neural Networks
(APNNs). APNNs have a multi-module, multi-level, and multi-modal design that works with …
