Distinguishers on round-reduced AES have attracted considerable attention in the recent years. Although the number of rounds covered in key-recovery attacks has not been increased since, subspace, yoy...
A THRESHOLD-FREE FILTERING ALGORITHM FOR AIRBORNE LIDAR POINT CLOUDS BASED ON EXPECTATION-MAXIMIZATION
Airborne LiDAR Point clouds Filtering Ground points Expectation-maximization Intensity
2018/5/14
Filtering is a key step for most applications of airborne LiDAR point clouds. Although lots of filtering algorithms have been put forward in recent years, most of them suffer from parameters setting o...
Automatic Expectation and Variance Computing for Attacks on Feistel Schemes
Generic attacks on Feistel type schemes pseudo-random permutations differential cryptanalysis
2016/2/23
There are many kinds of attacks that can be mounted on
block ciphers: differential attacks, impossible differential attacks, truncated
differential attacks, boomerang attacks. We consider generic di...

Introducing an Outcome Expectation Questionnaire and Its Psychometric Properties Regarding Leisure Time Physical Activity for Iranian Male Adolescent
Exercise Adolescent Questionnaires Reproducibility of Results Cognition Iran
2015/11/6
Background: Outcome expectation (OE) is known as a psychosocial determinant of leisure time physical activity (LTPA). Despite importance of this construct evaluation, there is no evidence of special q...
The role of temporal predictability in semantic expectation: An MEG investigation
Prediction Expectation Semantic
2015/9/2
Prior research suggests that prediction of semantic and syntactic information prior to the
bottom-up input is an important component of language comprehension. Recent work in
basic visual and audito...
Computing the Distribution Function of a Conditional Expectation via Monte Carlo: Discrete Conditioning Spaces
Probability algorithms distribution functions conditional expectation
2015/7/8
We examine different ways of numerically computing the distribution function of conditional expectations where the conditioning element takes values in a finite or countably infinite outcome space. Bo...
Cross-lingual Projected Expectation Regularization for Weakly Supervised Learning
Cross-lingual Projected Expectation Regularization Weakly Supervised Learning
2015/6/12
We consider a multilingual weakly supervised learning scenario where knowledge from annotated corpora in a resource-rich language is transferred via bitext to guide the learning in other languages. Pa...
Likely values of the Higgs vacuum expectation value
Function the higgs vacuum expectations the atoms the standard model the yukawa coupling
2014/12/18
We make an estimate of the likelihood function for the Higgs vacuum expectation value (vev) by imposing anthropic constraints on the existence of atoms while allowing the other parameters of the stand...
Generalized Expectation Criteria for Lightly Supervised Learning

2014/12/18
Machine learning has facilitated many recent advances in natural language processing and information extraction. Unfortunately, most machine learning methods rely on costly labeled data, which impedes...
Factored expectation propagation for input-output FHMM models in systems biology
input output factored hidden Markov models approximate inference variational inference expectation propagation systems biology microarray data
2013/6/14
We consider the problem of joint modelling of metabolic signals and gene expression in systems biology applications. We propose an approach based on input-output factorial hidden Markov models and pro...
Computing the posterior expectation of phylogenetic trees
Bayesian statistics BHV tree space Frechet mean geometric median phylogenetic trees posterior expectation
2013/6/14
Inferring phylogenetic trees from multiple sequence alignments often relies upon Markov chain Monte Carlo (MCMC) methods to generate tree samples from a posterior distribution. To give a rigorous appr...
Expectation Propagation for Neural Networks with Sparsity-promoting Priors

2013/4/28
We propose a novel approach for nonlinear regression using a two-layer neural network (NN) model structure with sparsity-favoring hierarchical priors on the network weights. We present an expectation ...
