Comparing Different Classifiers for Automatic Age Estimation

Lanitis, A.; Draganova, C.; Christodoulou, Chris C. (2004)

We describe a quantitative evaluation of the performance of different classifiers in the task of automatic age estimation. In this context, we generate a statistical model of facial appearance, which is subsequently used ...

Critical mass of Wilson fermions: A comparison of perturbative and Monte Carlo results

Follana, E.; Panagopoulos, Haralambos G. (2001)

We calculate the critical value of the hopping parameter, κc , in lattice QCD with Wilson fermions, to two loops in perturbation theory. This quantity is an additive renormalization
