With the continuous development of data science and financial technology, financial data visualization methods have become an essential key technology in the field of financial data analysis today. From the technical point of view, the mainstream visualization analysis takes the fusion of large screen and multiple views, and the nature of its visualization effect is more focused on the enumeration display, without fully analyzing the data characteristics from the essence. The single view visualization analysis technology is difficult to get clear and effective visualization display through correlation analysis, dimensionality reduction algorithms and principal component analysis. From the application point of view, credit card customer data, as an important part of financial data, has positive practical significance in customer profiling, product recommendation and risk prediction, and the targeted improvement research of its visualization method has an important role. The semantic feature group method combines the domain knowledge and data distribution characteristics of credit card customer churn data, composes and analyzes the semantic feature groups, and obtains explicit visualization and analysis results by combining the understanding of the actual problem and the numerical characteristics of the data itself. The accuracy and efficiency of the data representation based on the semantic feature group method are verified by comparing the data dimensionality reduction visualization methods such as multi-view fusion method, T-distribution random neighborhood embedding and principal component analysis in the experiment. © 2023 SPIE.

To enable mobile robots to perform different tasks intelligently and autonomously in different work scenarios, we usually use SLAM to achieve simultaneous localization and map building of the robot mainly using to complete the functions. Localization and mapping are done only by detecting and matching feature points in the image, which only utilizes the geometric information in the environment and cannot obtain the linguistic information in the environment, resulting in the robot not being able to perceive the surrounding environment well. Location and mapping can only be done by detecting and matching the feature points in the image. Only the geometric information in the environment is used, and the linguistic information in the environment cannot be obtained, which makes the robot unable to perceive the environment well. In this paper, a three-dimensional semantic map is implemented based on the system design. The data uses RGBD image sequence, and the target detection algorithm YOLOv4 is applied to ORB-SLAM2 system to extract the semantic information in the environment. A three-dimensional dense point cloud map constructed by ORB-SALM2 system is segmented using an improved LCCP algorithm. Semantic information in the environment is projected to the three-dimensional point cloud according to the globally consistent camera posture, and a three-dimensional dense point cloud map with semantic information is constructed. © 2023 SPIE.

In terms of music genre classification, neural networks and machine learning models have their respective advantages. This paper aims to compare the performance and feature extraction capability between neural networks and traditional machine learning algorithms on music genre classification. All the components of 9 main music features, each with seven statistical values, were extracted as essential features, and different dimension reduction methods were applied. This paper compares the performance of training the features by neural networks and machine learning models. Finally, this paper used the output of layers in the neural networks as features and applied traditional machine learning models for training to see if their performance could be optimized. The result showed that the performance was raised by about 20%, compared to the essential features, and raised by about 5%, compared to the reduced features. So, it can be concluded that the feature extraction capability of neural networks is better than traditional machine learning models. Also, using features filtered by neural networks and applying traditional machine learning models for training is a method providing both excellent performance and high efficiency. © 2022 IEEE.

With the rapid development of the Internet of Things and the exploration of its application scenarios, embedded devices are deployed in various environments to collect information and data. In such environments, the security of embedded devices cannot be guaranteed and are vulnerable to various attacks, even device capture attacks. When embedded devices are attacked, the attacker can obtain the information transmitted by the channel during the encryption process and the internal operation of the encryption. In this paper, we analyze various existing white-box schemes and show whether they are suitable for application in IoT. We propose an application of WBEAs for distributed devices in IoT scenarios and conduct experiments on several devices in IoT scenarios. © 2022 IEEE.

Scene classification is a popular and important question in computer vision and has been developed in different areas. Applying computer vision to artworks has become a popular topic in recent years. However, the traditional random sampling to identify the artworks through machine learning requires a large data set and, therefore, a higher cost to get a solid result. This paper compares random sampling and active learning (uncertainty sampling) performance using a data set (8446 paintings) of the 50 most influential painters in Europe from the 13th to the 20th century. and then propose that the active learning strategy can build a stronger model that requires smaller data sets. The active learning model can be further improved through training in larger data sets and applied in the artwork recognition for artificial intelligence.. © 2022 IEEE.

In the process of auto parts products from manufacturing to quality inspection, it is inevitable that there will be defects on the surface due to aging of machine tools or human factors. How to better apply computer vision technology to defect detection of auto parts is still an issue discussed by the industry and academia. For the condition that sufficient labeled samples is usually not available in the industrial field, this paper uses an improved few-shot metric learning model to identify auto parts samples. According to the traditional few-shot learning models lack of the considerations of channel level and internal relations of support set, this paper adds ECA module and Transformer module to few-shot learning. Add more attention to the key information of support set and query set samples at channel level while increasing the attention to the intrinsic feature of support set, to improve the classification effect. © 2022 IEEE.

In an increasingly information-based modern society, online shopping has gradually become the first choice for people to buy goods. Therefore, more and more e-commerce platforms have emerged, such as Tmall, JD, etc., and e-commerce economy has gradually become an important part of promoting social progress. Since most e-commerce reviews are short texts, it takes a lot of time for consumers to search for useful information for themselves. Therefore, this paper clusters short texts for the first time, and takes the user's review text as the input of the model to get the clustering results. The review text with similar views will be grouped into the same cluster, At the same time, we can get the topic words in each cluster, that is, where consumers pay most attention in the consumption process. Due to the large number of comment texts, we use Dirichlet and multinomial mixed model as the first clustering model, because this model does not need to set the clusters number in advance, and has good performance on large-scale data sets. For the results of the first clustering, although consumers' concerns can be analysed, it is difficult to judge consumers' attitudes, so we take the subject words in the clustering results as input to form a new short text, use TF-IDF to extract the features of the short text constructed by the subject words, then use K-means method to judge the emotional polarity, and then use homogeneity, integrity NMI effectively evaluates the clustering results. Through the experimental results of two clusters, we can clearly find out where consumers pay most attention after purchasing a certain commodity. For example, after purchasing clothes, most consumers focus on the materials and brands of clothes. After clustering, we can get the clustering results of all consumers and the clustering subject words, that is, consumers in the same cluster have similar concerns about goods. After the second clustering, the emotional polarity of consumers can be analyz

Abstractive text summarization is an important research field in natural language learning. Compared with the extracted text summary, it is more in line with the preparation steps of the manual summary. In traditional machine learning, supervised learning is the main method. Text annotation, feature extraction, classification training, and weight extraction are also very different from those based on deep learning. Starting with the task of abstractive text summarization based on deep learning, this paper summarizes the current research status of abstractive text summarization, in-depth analysis of multiple designs of encoder-decoder for current deep learning methods, and points out the difficulties of current research and the hot direction of future development. © 2022 IEEE.
