Genetic Algorithm and Data Mining Techniques for Design Selection in Databases
Nowadays, variable selection is fundamental to large dimensional statistical modelling problems, since large databases exist in diverse fields of science. In this paper, we benefit from the use of data mining tools and experimental designs in databases in order to select the most relevant variables for classification in regression problems in cases where observations and labels of a real-world dataset are available. Specifically, this study is of particular interest to use health data to identify the most significant variables containing all the necessary important information for classification and prediction of new data with respect to a certain effect (survival or death). The main goal is to determine the most important variables using methods that arise from the field of design of experiments combined with algorithmic concepts derived from data mining and metaheuristics. Our approach seems promising, since we are able to retrieve an optimal plan using only 6 runs of the available 8862 runs.
In order to help manager to make termination decision for the ongoing RD project timely and correctly, the authors review and compare the theory and methodology of termination decision from the literature. Furthermore, we discuss the considerable importance to identify attributes of an ongoing RD project. To identify attributes of an ongoing RD project, the authors examine characteristics and scopes of neural network. Thus, the feasibility of neural network, which is possibly used in RD project termination decisions, is further explored. On the basis of the theory and methodology of neural network, this study attempts to develop a mode identification method to make RD project termination decisions in an effective manner. Finally, the validity of the proposed method is verified by an example. The result shows that the method is both simple and practical.
