借助于人工智能搜索技术
Xu等人提出了计算量优于B
&
B算法的全局最优特征提取BF*算法。本文在分析了BF*算法搜索树T
B
结构的基础上
提出了一种比T
具有更少节点的搜索树T
b
及相应的BF**算法。并证明
在不另增加存贮量和保持全局最优特性的前提下
BF**算法在计算量方面优于BF*算法。
With AI technology in searching
Xu
et al. presented a global optimum feature selection algorithm
BF
which is computationally superior to B&B one. Based on the analysis of search tree TB used in BF
this paper proposes a new structure of search tree
Tb
on which there are fewer nodes than on TB. A feature selection algorithm on Tb
referred as to BF
is designed
of which the computational complexity is lower than BF’s
without increasing storage and with global optimum property.
