php-symfony-security

infrastructure for sophisticated authorization systems

The Symfony Security Component makes it possible to easily separate authorization logic from user providers that hold the users credentials. It ships with facilities for authenticating using HTTP basic or digest authentication, interactive form login or X.509 certificate login. Furthermore it optionally also allows an application to implement its own authentication strategies. In addition the component contains an advanced ACL system and provides ways to authorize authenticated users based on their roles.

r-cran-rocr

GNU R package to prepare and display ROC curves

ROC graphs, sensitivity/specificity curves, lift charts, and precision/recall plots are popular examples of trade-off visualizations for specific pairs of performance measures. ROCR is a flexible tool for creating cutoff-parametrized 2D performance curves by freely combining two from over 25 performance measures (new performance measures can be added using a standard interface). Curves from different cross-validation or bootstrapping runs can be averaged by different methods, and standard deviations, standard errors or box plots can be used to visualize the variability across the runs. The parametrization can be visualized by printing cutoff values at the corresponding curve positions, or by coloring the curve according to cutoff. All components of a performance plot can be quickly adjusted using a flexible parameter dispatching mechanism. Despite its flexibility, ROCR is easy to use, with only three commands and reasonable default values for all optional parameters.

libio-event-perl
