Fractal Dimension and Dimensionality Reduction

ABSTRACT In this paper we investigate the relationship between several dimensionality redu tion methods and the intrinsi dimensionality of the data in the redu ed spa e, as estimated by the fra tal dimension. We show that a su essful dimensionality redu tion/feature extra tion algorithm proje ts the data into a feature spa e with dimensionality lose to the intrinsi dimensionality of the data in...

Extension of Cube Attack with Probabilistic Equations and its Application on Cryptanalysis of KATAN Cipher

Cube Attack is a successful case of Algebraic Attack. Cube Attack consists of two phases, linear equation extraction and solving the extracted equation system. Due to the high complexity of equation extraction phase in finding linear equations, we can extract nonlinear ones that could be approximated to linear equations with high probability. The probabilistic equations could be considered as l...
