In statistics, the expectation–maximization (EM) algorithm is an iterative method for finding maximum likelihood or maximum a posteriori (MAP) estimates of parameters in statistical models, where the model depends on unobserved latent variables.
For this reason EM is frequently used for data clustering, verification and identification of the speaker (biometric tasks), author profiling based on his documents, automatic document categorization, and many more applications.

In order to compile this program, you need first compile and install the zlib library from their website, or using your preferred software distribution channels (aptitude, yum, macports, etc) in order to install it (with the dev packages). On some systems this library can be installed by default.
On Mac Os X and Linux distributions you can simple use the make command on the system shell to compile it, and then sudo make install to install it on yout system (by default on /usr/bin). We recommend the use of the lastest version of the GCC compiler (because the code generated by LLVM is, for now, much slower).
