On the Virtues of Generic Programming for Symbolic Computation
The purpose of this study is to measure the impact of C level code polynomial arithmetic on the performances of AXIOM highlevel algorithms, such as polynomial factorization. More p...

An Improved Algebraic Attack on Hamsi-256
Hamsi is one of the 14 second-stage candidates in NIST’s SHA-3 competition. The only previous attack on this hash function was a very marginal attack on its 256-bit version publi...

New Commutative Semifields and Their Nuclei
Abstract. Commutative semifields in odd characteristic can be equivalently described by planar functions (also known as PN functions). We describe a method to construct a semifield...

Constrained monotone regression of ROC curves and histograms using splines and polynomials
Receiver operating characteristics (ROC) curves have the property that they start at (0,l) and end at (1,O) and are monotonically decreasing. Furthermore, a parametric representat...

A variational EM algorithm for learning eigenvoice parameters in mixed signals
We derive an efficient learning algorithm for model-based source separation for use on single channel speech mixtures where the precise source characteristics are not known a pri...
