With the development of frequent items and frequent sequences mining, the technology of data mining turns to solve the problem of structural pattern mining. In this paper, we introduce transformation rules and define a new representation of tree sequences by using transformation sequences. Then we propose an efficient approach to enumerate frequent transformation subsequences (FTSs) of trees from...
How to create highly-reputable designs and hot-selling products is an essential issue on product design. This paper presents an experimental study to explore the relationship between the consumers' perceptions and product form elements, using one linear quantitative technique (i.e. the grey model) and one nonlinear quantitative technique (i.e. the neural network model). Thirty representative personal...
This paper mainly discussed the properties of orthomorphic latin square, the equivalent relation between orthomorphism and orthomorphic latin square transversal, proposed a constructing method of orthomorphism by orthomorphic latin square transversal, counted the number of orthomorphisms and obtained a better lower bound of orthomorphisms.
