Monopulse antenna can provide multiple beams simultaneously and use single pulse echo signal to form sum and difference signals for ranging and angle measurement. As the front end of the monopulse radar system, the performance of the monopulse antenna is crucial to the range detection and angle measurement accuracy of the radar system. For the monopulse antenna system, the pattern characteristics determine its performance. In this paper, the factors affecting the pattern characteristics of monopulse antenna are studied.

Recently, quantitative investment has become a new way of investment finance, which combines the model with the computer to predict the investment stock trend more efficiently and accurately. Stock trend forecasting is one of the difficult and important tasks in modern quantitative investment systems. With the development of artificial intelligence technology, many deep learning models have emerged. The application of deep learning in the stock market not only reduces the difficulty of stock analysis and trend prediction, but also introduces new investment methods and ideas for investors. However, most of the models are based on volume and price data, and the consideration of stock relationships are relatively simple, so we propose a Spatial-Temporal Graph Neural Network model fusing Barra factors (BSTGNN), which integrates factor knowledge, mines potential inter-stock relationships, and fully consider the heterogeneity of the relationship. The experiments conducted on the real-world stock market dataset prove that BSTGNN perform better than the baseline methods.

Pseudo-labeling has emerged as a popular and effective approach for utilizing unlabeled data. However, in the context of semi-supervised multi-label learning (SSMLL), conventional pseudo-labeling methods encounter difficulties when dealing with instances associated with multiple labels and an unknown label count. These limitations often result in the introduction of false positive labels or the neglect of true positive ones. To overcome these challenges, this paper proposes a novel solution called Class-Aware Pseudo-Labeling (CAP) that performs pseudo-labeling in a class-aware manner. The proposed approach introduces a regularized learning framework incorporating class-aware thresholds, which effectively control the assignment of positive and negative pseudo-labels for each class. Notably, even with a small proportion of labeled examples, our observations demonstrate that the estimated class distribution serves as a reliable approximation. Motivated by this finding, we develop a class-distribution-aware thresholding strategy to ensure the alignment of pseudo-label distribution with the true distribution. The correctness of the estimated class distribution is theoretically verified, and a generalization error bound is provided for our proposed method. Extensive experiments on multiple benchmark datasets confirm the efficacy of CAP in addressing the challenges of SSMLL problems. The implementation is available at https://***/milkxie/SSMLL-CAP.

Clustering is the solution for grouping a plenty of data when there is no knowledge of the classes. Clustering is typically a well-known algorithm in the origins of machine learning or artificial intelligence. However, artificial intelligence is, unfortunately, relatively hard to understand for some reasons, hence, followed by the rise of explainable artificial intelligence research. In this paper, we propose an alternative approach to grouping problem-solving by using a dynamic programming procedure in the context of dynamic time warping. We conduct a cluster analysis in stagewise optimization with the following four steps; (1) define an optimal value function, (2) formulate recurrence relation, (3) set the boundary condition, and (4) answer is given by. We also demonstrate a numerical example along with its table-filling solution in the case of grading students' scores into $k$ clusters. The results conclude that dynamic time warping algorithm may have preferences to be an alternative solution for certain machine learning tasks beyond traditional unsupervised methods instead.
