摘要:

特征选择是机器学习中最具挑战性的问题之一,特别是在处理高维数据时。在本文中,我们解决的问题,特征选择,并提出了一种新的方法,称为进化快,慢。这种新方法是基于使用两个并行的遗传算法具有高和低的突变率,分别。进化的快与慢需要一种新的并行架构,将快速进化的自动系统和缓慢进化的努力系统结合起来。有了这个体系结构,探索和开发可以同时进行。具有高突变率的快速进化可用于利用长跳跃来探索搜索空间中的新未知位置;具有低突变率的缓慢进化可用于利用短移动来利用搜索空间中的先前已知位置。我们的实验表明,进化快和慢实现了非常好的结果,在准确性和功能消除。

英文摘要:

Feature selection is one of the most challenging issues in machine learning, especially while working with high dimensional data. In this paper, we address the problem of feature selection and propose a new approach called Evolving Fast and Slow. This new approach is based on using two parallel genetic algorithms having high and low mutation rates, respectively. Evolving Fast and Slow requires a new parallel architecture combining an automatic system that evolves fast and an effortful system that evolves slow. With this architecture, exploration and exploitation can be done simultaneously and in unison. Evolving fast, with high mutation rate, can be useful to explore new unknown places in the search space with long jumps; and Evolving Slow, with low mutation rate, can be useful to exploit previously known places in the search space with short movements. Our experiments show that Evolving Fast and Slow achieves very good results in terms of both accuracy and feature elimination.
