Exponentiated Gradient Algorithms for Conditional Random Fields and Max-Margin Markov Networks
Log-linear and maximum-margin models are two commonly-used methods in supervised machine learning, and are frequently used in structured prediction problems. Efficient learning of...

Randomly shifted lattice rules for unbounded integrands
We study the problem of multivariate integration over Rd with integrands of the form f(x)d(x) where d is a probability density function. Practical problems of this form occur comm...

An EEG-based BCI system for 2D cursor control
Abstract— In this paper, an electroencephalogram (EEG)based brain computer interface (BCI) is proposed for two dimensional cursor control. The horizontal and vertical movements o...

Bias in the LEVIATHAN Stream Cipher
We show two methods of distinguishing the LEVIATHAN stream cipher from a random stream using 236 bytes of output and proportional effort; both arise from compression within the ci...
