Missing values often exist in scientific datasets. Therefore, practical methods for missing data imputation and classification are necessary for machine learning, data analysis. The k-Nearest Neighbor (KNN) algorithm is a simple and effective algorithm in missing data imputation and classification. This paper focuses on the missing data classification problem and proposes a new classification method based on the local mean k-nearest centroid neighbour. When making classification judgments, the proposed method examines the closeness and symmetrical arrangement of the k neighbours and adopts the local mean-based vector of the k centroid neighbours for each class. We run classification error experiments on six UCI datasets to see how well the proposed method performs when there is missing data. Experimental results show that the performance of our proposed method obtains a significant improvement compared to the most advanced KNN-based algorithms.

The text of power grid business cost demand is complex and the description cannot be unified and standardized. As a single text description involves multiple business types, it is difficult to judge the business cost type. This paper presents a classification method of clustering specific cost types for business cost requirements text. Firstly, the business cost requirement text is transformed, and the key weight parameters in the Chinese word segmentation model are improved iteratively according to the cost representation report to obtain the global semantic vector. At the same time, the weights of recognition loss values of different samples were dynamically modified according to the difficulty of sample fitting. In this paper, the existing text clustering model is improved by k-means clustering algorithm model, and the cost types of 450 real business cost demand texts in the province are identified. The results show that the performance index value of the text classification method proposed in this paper is better than the commonly used text classification method, and the F1 value of the algorithm in this paper reaches more than 93%. The value of F1 is more than 3.5% higher than that of single BERT model.

The key challenges of the financial industry are the volatility and complexity of the stock market, so how to make optimal trading strategy to maximize the total profit in all market conditions has become an important issue to the professional researchers and investors. This paper describes a hybrid stock trading strategy model based on long short-term memory (LSTM) networks. The Complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) algorithm and sample entropy (SE), combined with LSTM, are used to construct the integrated prediction model, which has dramatically improved the forecast precision. On the premise of accurate prediction, the extreme value theory (EVT) is introduced to improve the predictive ability of dynamic value at risk (VaR), which can manage the risk of portfolio. To forecast stock trends, the approach of analytic hierarchy process (AHP) is applied to assign weights to related factors. The final trading decisions are made by establishing trading signals and scoring models. Based on models above, the integrated trading strategy model is constructed as an automated trading decision tool. Taking Gold and Crude oil as examples, the profit results are proved to be decent through trading simulations.

With the development of social economy, the market mechanism tends to be perfect, which promotes the tourism industry to a new height. With the rapid development of tourism industry, management problems have become increasingly prominent. This paper makes an in-depth analysis of tourism planning and management from multiple perspectives. In view of the poor performance of the original optimal tourism route optimization model in obtaining the shortest route, this paper constructs the optimal tourism route optimization model based on ant colony optimization algorithm, sets the route selection process, and uses ant colony algorithm to complete the optimal route selection. According to the results of route selection, pheromone update rules and route model format are set to complete the construction of optimal route optimization model. Compared with the traditional model, the path chosen by the model is shorter and the cost is lower. At the same time, using BP neural network model and matlab calculation program to evaluate tourism resources can avoid the influence of subjective factors on the evaluation results to the greatest extent. On this basis, the evaluation model is designed, and the error value of the evaluation model is analyzed. This paper mainly focuses on the relevant measures of tourism management and puts forward a tourist flow forecasting model based on data mining. Firstly, the historical data of tourism flow are collected, and then the chaos algorithm is introduced to construct the learning sample of tourism flow prediction. Finally, the particle swarm optimization algorithm is introduced to optimize the parameters of the tourist flow forecasting model. The simulation results show that, compared with the BP neural network optimized by particle swarm optimization and support vector machine, this model can describe the changing characteristics of passenger flow in scenic spots more accurately, and the prediction error of passenger flow in scenic spots is much smaller than that of the contrast model, and a more ideal passenger flow prediction result is obtained, which can put forward a new solution strategy in the field of tourism management.

The ILS electromagnetic environment can easily be changed by large objects reflection, which result in degradation of the signal-in-space. Therefore, how to choose a suitable localizer antenna is very important. The higher the operating category of ILS is, the stricter requirements for the localizer course structure will be, especially for Category Ⅱ/III, In the paper, three typical antennas are compared by computer simulation, and the results show the scalloping of course structures under different types of antennas. Computer simulation is very helpful to study the selection of localizer antenna for ILS Category Ⅱ/III. Computer simulation can identify the structure disturbance before construction and help engineers find solutions. This can also effectively protect electromagnetic environment of the airport and ensure operation safety.
