The commercial banks need identify exceptional client in their large number of customers to prevent abnormal customer's risk. In this paper, four types of abnormal data detection method is introduced, present a new method- the k-medoids clustering algorithm combining genetic algorithm to detect the outlier. Finally, apply the algorithm to analysis credit data sets, detect outlier and identify abnormal...
The angle of break is a key factor that determines the mining damage extent of the surface in a mine, and it is also used to depict the characteristics of the mining subsidence basin. The geological and mining factors that influence the angle of break are fully analyzed. Based on the practical observational data from the ground movement monitoring stations of many mines in China, a neural network...
Genetic algorithm (GA), as a kind of important intelligence computing tool, is a wide research content in the academic circle and the application domain now. In this paper, for the mutation operation of GA, by combining with the essential feature, from structural and visualized angle, we implement different mutation strategy to individual of different fitness value in every generation, and establish...
Financial crimes such as money laundering are often committed by cooperative individuals in a hidden manner. Discovering hidden group in financial transaction networks can help to find suspects of money laundering. A method is presented to discover the hidden group based on hidden Markov model (HMM) and genetic algorithm. HMM is used to describe financial transaction network. The maximum likelihood...
Particle swarm optimization (PSO) is similar to genetic algorithm (GA) but employs different strategies and computational effort. Strategic defense military games require a high degree of coordination among the characters and thus are suitable to test the performance of algorithms. In this paper, we design a scenario of tower defense game and compare the performance of PSO and GA in terms of the damage...
We introduced a new evolutionary based algorithm and named it bisected algorithm. Bisected algorithm mimics the behavior of living creatures which reproduce through bisection. In the present study we have approached the problem from a biological perspective and extended the bisected algorithm.
By researching all kinds of methods for document clustering, we put forward a new dynamic method based on genetic algorithm (GA). K-means is a greedy algorithm, which is sensitive to the choice of cluster center and very easily results in local optimization. Genetic algorithm is a global convergence algorithm, which can find the best cluster centers easily. Among the traditional document clustering...
Genetic algorithm (GA), as a kind of important intelligence computing tool, is a wide research content in the academic circle and the application domain now. In this paper, for the mutation operation of GA, by combining with the essential feature, we establish a genetic algorithm based on schema mutation (denoted by SM-GA, for short). Further, we discuss the global convergence of CM-GA by using the...
In this paper an improved genetic algorithm is proposed to solve optimal problems applying fixed point algorithms of continuous self-mapping in Euclidean space. The algorithm operates on subdivision of searching space and generates the integer labels at the vertices, and then only mutation operator relying on the genetic encoding designed which is proposed by virtue of the concept of relative coordinates...
