The invention discloses a personalized commodity recommending method which integrates attributes and structural similarity. In the method, users and commodities are used as nodes with characteristic information to be mapped to a network by integrating the attribute information and structural similarity information, and an information network chart is established according to the purchasing relation between customers and the commodities; and interests and preference among user node pairs are measured by the integrated attributes and structural similarity in the information network chart, and the nearest neighbor is selected by the interests and the preference to improve the accuracy of recommending. On the basis of the recommending method, the invention also discloses a personalized commodity recommending method which integrates the measurement of the attributes and the structural similarity. In the system, the interests and the preference of the users are measured accurately by a computing method of integrating the similarity of the attributes and the similarity of node structure backgrounds in the information network chart, and the generation efficiency of the nearest neighbor is improved by utilizing clustering technology. The method and the system can be applied to electronic commerce, and provide personalized commodity recommending for the users.

Automatic generation method for handwritten Chinese font library based on deep neutral network

The invention discloses an automatic generation method for a handwritten Chinese font library based on a deep neutral network. The method is characterized in that font characteristics are reconstructed through a small number of handwritten Chinese characters; a font style migration network is established; and font style characteristics of font forms not handwritten by a user are estimated throughthe font style migration network, font form contents of a reference font are combined with a handwriting style of the user to achieve migration to a target handwriting style, and target font form pictures are generated, so that the complete handwritten Chinese font library is obtained. The method provided by the invention has the advantages that the method is an end-to-end generation method, and high-quality Chinese font forms are generated without extraction of strokes or components of Chinese characters or manual intervention, so that the handwritten font library creation efficiency is greatly improved, the generation of a personalized font library becomes simple and convenient, the requirement of ordinary people for the personalized handwritten font library can be met, and the development progress of the personalized font library can be accelerated.

Method for preparing electrodes of super capacitor based on nickel foam and products thereof

The invention discloses a method for preparing electrodes of a dissymmetric super capacitor based on nickel foam. The method comprises the steps: washing the nickel foam, soaking the nickel foam into a graphene oxide aqueous solution to obtain nickel foam in which graphene oxide deposits, serving the nickel foam in which the graphene oxide deposits as precursor materials, and respectively adopting a three-electrode method for preparaing a positive electrode and a negative electrode of the dissymmetric super capacitor, wherein the positive electrode is composed of composite materials of graphene, a carbon nanometer tube and the nickel foam, and the negative electrode is composed of composite materials of graphene, manganese dioxide and the nickel foam. The invention further discloses some other methods for preparing the electrodes of the super capacitor based on the similar principle, and products which correspond to the methods. By means of the methods and the products, respective high-ratio capacitance characteristics of the composite materials are fully played, and energy density of the super capacitor is improved. In addition, usage of various combined reagents can be avoided, and accordingly large-batch industrial production is conducted in a mode of convenient control, low cost and low energy consumption.
