Linear and non-linear filtering in stereopsis
Vision Research, 1994To better understand the spatial filtering operations underlying stereopsis, and their relationship to those underlying monocular localization of the same stimuli, we examined the dependence of stereoacuity on carrier and envelope size of Gabor patches.

On the Independence of Linear Functionals of Linear Processes
SIAM Journal on Applied Mathematics, 1969A class of continuous parameter random processes is defined whose members, $x(t)$, are integrals of a nonstationary random “filter” function, $h(t,\lambda )$, with respect to an independent increments process $Z(\lambda )$. Linear functionals l of $x(t)$ expressible as integrals of a random function $\phi (\lambda )$ with respect to $Z(\lambda )$ are ...

Linearity and non-linearity in cerebral hemodynamics
Medical Engineering & Physics, 2003Transcranial Doppler ultrasound has been extensively used to study cerebral hemodynamics, and yet the basic characteristics of the input/output system of blood pressure/velocity are little known. We examine whether this system can best be considered linear or non-linear.We assessed the adequacy of linear modeling in four ways: (1) Known properties of ...

Linear Systems and Linearization
2010Key to the analysis of nonlinear systems is determining the stability of the equilibria. The classical method of determining stability is to linearize the system about the equilibrium and to determine exponential rates of growth and decay for the associated linear system. The framework for carrying this out is taken up in this chapter.

Training linear SVMs in linear time
Proceedings of the 12th ACM SIGKDD international conference on Knowledge discovery and data mining, 2006Linear Support Vector Machines (SVMs) have become one of the most prominent machine learning techniques for high-dimensional sparse data commonly encountered in applications like text classification, word-sense disambiguation, and drug design. These applications involve a large number of examples n as well as a large number of features N, while each ...

On Linear Cryptanalysis with Many Linear Approximations
2009In this paper we present a theoretical framework to quantify the information brought by several linear approximations of a block-cipher without putting any restriction on these approximations. We quantify here the entropy of the key given the plaintext-ciphertext pairs statistics which is a much more accurate measure than the ones studied earlier.

Non-linearity as the Metric Completion of Linearity
2013We summarize some recent results showing how the lambda-calculus may be obtained by considering the metric completion (with respect to a suitable notion of distance) of a space of affine lambda-terms, i.e., lambda-terms in which abstractions bind variables appearing at most once.
