用最大似然估计训练分类器，用Train.txt里的数据进行训练，用Test.txt的数据进行性能检测(Use the maximum likelihood estimation training classifier, use the data in Train.txt to train the classifier and use the data in Test.txt to test the performance of the classifier)

用最优化方法解决最优化问题的技术称为最优化技术，它包含两个方面的内容： (1)建立数学模型，即用数学语言来描述最优化问题。模型中的数学关系式反映了最优化问题所要达到的目标和各种约束条件； (2)数学求解，数学模型建好以后，选择合理的最优化方法进行求解。 (With optimization method to solve the optimization technology, called the optimum technology, it contains two aspects: (1) established the mathematical model, which is the mathematical language to describe the optimization problem. Model of the mathematical relationship reflects the optimal problem to achieve and all constraint conditions (2) solving mathematics, mathematical model built after, choice of reasonable solution of the optimization method.)
