In the optimization process of multi‐objective firefly algorithm, population is easy to fall into local optimum, which leads to poor population distribution and convergence. In order to solve this problem, this article proposes a multi‐objective firefly algorithm with multi‐strategy integration (MOFA‐MSI). First, in order to improve the distribution of population, MOFA‐MSI proposes a cloning strategy,...
This paper proposes an improved K-Modes clustering method based on Chi-square statistics, using Chi-square statistics to characterize the relationship between the attributes of data objects. On this basis, the new distance measure is proposed, The distance measure method not only take into account the value of an attribute of an object different from itself, but also take into account other attributes'...
Proposed in this paper is a spam filtering method based on rough set theory and Bayesian classifier algorithm. First, mutual dependence model is used to extract the features of email content. Then the amount of features are reduced by deleting redundant features with little significance on filtering effect based on rough set theory, result in a input sample with reduced number of dimension. Experiments...
Aiming at the wider use of the hierarchical network topology as well as the cost of data allocation optimization strategy in this structure was obviously lower than the general network, a network hierarchical model and algorithm based on granular computing are proposed in the paper. This algorithm maps the complex network entirely to the hierarchical network, thus we can deal with the problems of...
