Abstract
A method of hop count matrix recovery based on a decision tree classifier, includes: S: performing a flooding process to acquire a hop count matrix {tilde over (H)} with missing entries; S: constructing a training sample set according to relationships between a part of observed hop counts in the hop count matrix {tilde over (H)}, and modeling the observed hop counts in the hop count matrix as labels of the training sample set, wherein a maximum hop count represents a number of classes; S: training a decision tree classifier according to the training sample set obtained in step S; and S: constructing a feature for an unobserved hop count, to obtain an unknown sample; and inputting the unknown sample to the trained decision tree classifier, to obtain a class of the unknown sample which represents a missing hop count at a corresponding position in the matrix, to recover a complete hop count matrix H.
