In order to avoid the curse of dimensionality, which is often encountered in big data analysis, manifold learning assumes that high-dimensional data is embedded in a low-dimensional smooth manifold. However, in practical applications, the data sets often contain inevitable noise, and the manifold learning algorithm itself is often sensitive to noise. Therefore, in order to reduce the interference of noise to the manifold learning algorithm, we propose a new projective noise reduction algorithm based on Laplacian smoothing. The main idea of this algorithm is to perform Laplacian smoothing on a data set before projection of the sample points, so that the data set can present expected manifold structure, which solves the problem that the sample points are too scattered and deviated from the main manifold well. In avoid of the over-smoothing problem caused by Laplacian smoothing algorithm, we propose to control the number of iterations based on the variance reduction. The experimental results show that the proposed algorithm can reduce the noise as well as maintain the manifold structure, and the noise reduction effect is superior to the traditional noise reduction algorithm.

On the background of more and more demands for the evaluation of municipal engineering projects, the benefits of municipal engineering are paid more and more attention, and, at present, the research focus in the field of engineering is more on the benefit of single index than comprehensive evaluation benefits, this paper puts forward the concept of “comprehensive benefit” evaluation of municipal engineering based on various indicators of comprehensive engineering benefits. This paper puts forward an evaluation model of comprehensive benefits of municipal projects based on triangular fuzzy number and fuzzy comprehensive evaluation method, which can carry out post evaluation of comprehensive benefits of various municipal projects under various modes such as PPP, BT and BOT. Through example demonstration, it is proved that the evaluation model is scientific, practical and operable, which provides favorable engineering measures for the sustainable development of the city and the construction of a resource-saving and City friendly society.

In the Internet financial industry, it is of great significance to the user's credit default risk management, but the traditional machine learning model has low prediction accuracy. This paper proposes a two-stage credit default identification model based on BP-RF (Back Propagation Neural Network with Random Forest). Firstly, the feature of transaction data is extracted automatically by constructing the neural network, and then classified and predicted by the random forest algorithm. The model is verified with millions of data sets provided by the lending club. The results show that the model has better performance than the traditional model, with an accuracy of 95.1%, AUC index of 89.0% and ACC index of 93.1%, which proves that the model is more suitable for the field of credit default prediction.

In the era of big data, sharing economy relies on the rapid development of data analysis and acquisition technology, and it also drives the fast growth of short-term rental housing in the sector of housing. In this process of development, there are many deteriorating management problems, such as infringement of rights, potential fire hazards and disclosure of privacy. The resulting conflicts and disputes, accidents, and the issues of the public safety become more and more serious. In the face of the chaos of the short-term rental housing industry, according to the sample statistics and Internet big data research, this paper plugged up the management loopholes in the short-term rental housing management from the perspective of joint construction, joint governance and shared benefits in the new era. In terms of method, this paper analyzed the data by constructing the integral model, took the safety risk issues existing in the daily operation of short-term rental housing as the index, and established the model of “quantitative integral early warning mode for abnormal problems of short-term rental housing”. Besides, it divided the risk of short-term rental housing into three levels, i.e. medium-low risk, high risk and tremendous risk, and carried out the corresponding risk classification management.

By analyzing the previous order quantity, supplier's supply quantity and transshipment homeopathy quantity, this paper designed the ordering scheme of raw materials for a building and decoration board manufacturer, and considered the transportation of raw materials. First of all, this paper finds four factors that affect suppliers: total supply quantity, supply times, supply satisfaction rate and average supply completion rate, determines the coefficient by AHP, and considers scoring, and selects 50 most important suppliers. Next, select the important suppliers from top to bottom, and order their historical maximum supply every week until the maximum production capacity is met. According to the order price, give priority to a and c, and reduce b. Finally, select materials with low loss and high transportation yield. Finally, the number of selected enterprises is increased, and the most Class A materials and the least Class C materials are purchased, so as to maximize the production capacity and minimize the losses while ensuring that one supplier is transported by only one forwarder.

From the perspective of time evolution, it analysis the trends and changes of selected projects, journal distribution, domestic and foreign cooperation. It also uses the SciVal big data to explore the research topics. The research shows: (1) An important way for high Altmetrics papers to increase their influence is the media focus and reports. (2) In the long-term benign development process, domestic top journals have attracted the attention of many scholars in the world and the international media. It provided a good academic exchange platform for domestic scholars. (3) International social media mainly focuses on the climate environment, genetic technology, health and hygiene. It also focuses on two-dimensional nanomaterials, photocatalytic technology, quantum science and other emerging frontier fields.
