This is a tiny toolkit for performing training of maximum entropy models. It is a generic toolkit, which is applicable to conditional maximum entropy models. A special feature of this program is that it is written only in 132 lines of code (can be printed on one sheet of paper …). It includes training of model parameters, evaluation, perplexity and error rate computation, count-based feature reduction, Gaussian priors, feature count normalization. In addition, it is easy to use and efficient enough to deal with millions of features.
