Maxent是一种不像GLM那样成熟的统计方法,因此一般使用它的指导方针较少,估计预测中误差量的方法也较少。最大熵建模是统计和机器学习研究的一个活跃领域。有关最近的机器学习评论,可以参阅Olden等人于2008写的一篇文章“Machine learning methods without tears: A primer for ecologists” 。 Maxent 在R中的实现: Sys...

One of the advanced algorithms in the field of computer science is Genetic Algorithm inspired by the Human genetic process of passing genes from one generation to another.It is generally used for optimization purpose and is heuristic in nature and can be used at various places. For eg – ...
Genetic Programming (GP) is a type of Evolutionary Algorithm (EA), a subset of machine learning. EAs are used to discover solutions to problems humans do not know how to solve, directly. Free of human preconceptions or biases, the adaptive nature of EAs can generate solutions that are compa...

2.9 遗传算法(genetic algorithm) 遗传算法模拟生物繁殖的突变、交换和达尔文的自然选择(在每一生态环境中适者生存)。它把问题可能的解编码为一个向量,称为个体,向量的每一个元素称为基因,并利用目标函数(相应于自然选择标准)对群体(个体的集合)中的每一个个体进行评价,根据评价值(适应度)对个体进行选择、交换、变...
For example, the choice of appropriate representation and the corresponding set of genetic learning operators is an important set of decisions facing a user of a genetic algorithm. The study of genetic algorithms is proceeding at a robust pace. If experimental progress and theoretical understanding ...
