In order to solve practical problems such as kinship storage and inference by computer, based on algebra theory, an algebraic representation model for kinship relations in the Chinese context is proposed. The proposed model first determines the set of relationships to be studied based on the kinship contained in the national standard GBT-4761-2008, and then defines the inverse operation and the binary operation of kinship on this set. Finally, based on this algebraic representation model, a corresponding kinship inference algorithm is proposed. Some unknown kinship relationships can be inferred from known kinship relationships. Compared with the previous kinship inference algorithm, a new representation model is adopted, which can solve more complex problems.

To solve the cold start problem of new movies, a collaborative filtering recommendation algorithm (IW-CFW) based on BP neural network is proposed. In this algorithm, the similarity of movies is fused by BP neural network, and the BP network model is optimized and adjusted according to the error between the predicted score and the true score, and the final prediction model is obtained. By comparing the Mean Absolute Error (MAE) and Root Mean Square Error (RMSE) of the proposed algorithm with the other three algorithms on the Movielens and Movie-little datasets, the experimental results show that the proposed algorithm can effectively solve the cold start problem of new movies and produce more accurate recommendation results.

This paper introduces a method of image data transmission between AM5706 and FPGA through VIP(Video Input Port) interface. This method is a key technology of bill image scanning module. Bill image scanning module can collect two CIS image sensor signals, which are sent to FPGA for gray value compensation preprocessing after analog-to-digital conversion. FPGA accumulates a complete line of image data and outputs it to VIP interface of AM5706. Each time AM5706 VIP device receives a full image data, it will trigger a CPU interrupt. Compared with the traditional EMIF parallel bus + EMDA method, of which can only receive one line of image data at a time, using VIP interface can greatly reduce the CPU interrupt frequency and CPU resource utilization, which is of great significance to improve the system performance and reduce the hardware cost.
