The current paper describes how to set up a fuzzy expert system by using the fuzzy algorithm. A fuzzification interface, a fuzzy algorithm, and a defuzzification procedure make up a fuzzy expert system. Fuzzification methods are used in the construction of knowledge to convert exact numerical quantities into fuzzy values. The use of the fuzzy algorithm simplifies the study process for academics by facilitating the diagnosis of rice yield metrics, such as but not limited to the Number of tillers per Hill, Number of grains per panicle, and Pest and Disease incidence. A typical method is used in the given paper to perform working of fuzzy logic based on triangular approach. By using a defuzzification approach, we can transform vague or ambiguous values into precise or crisp ones. In order to create a fuzzy expert system for rice, the validation of the proposed approach is tested using MATLAB simulation.

The medical field and other research areas fields heavily rely on artificial intelligence (AI) and machine learning (ML). Hand gesture recognition (HGR), which is a straightforward approach for interacting with machines, has drawn the attention of numerous researchers in the context of AI. Utilizing ML technique, HGR is carried out. Both the image technique and the design approach are parts of it. In the image technique, the hand picture is rebuilt utilizing the attributes of the images. However, when using the model-based approach, the image is recreated using many models, including volumetric, geometric, and others. The key difficulty in gesture control continues to be the ML individual's complexity and preparation time. Its accuracy is used to assess the HGR accuracy. Its precision is used to assess the HGR overall system performance. The many techniques and algorithms utilized in gesture control are covered in detail inside this work.

Finding stolen cars is becoming increasingly important in many urban regions. An automated system for scanning license plates can recognize vehicle numbers without the need for human interaction. This work proposes a vehicle theft detectionsystem based on neural pattern recognition, gaussian filter, and equilibrium optimization. The proposed architecture has significant speedup and higher accuracy rates. The proposed number plate recognition method has a maximum accuracy rate of 94% and an average reduction in the processing time of 32%. Pattern recognition is the process of detecting regularities and patterns in data using machine learning. These analogies may now be uncovered via statistical analysis, historical data, or machine-generated knowledge.

Properly wearing a mask can help prevent many respiratory infections, such as COVID-19. The mask detectionsystem reminds people in public places to wear masks. Therefore, it is necessary to develop an efficient mask detection algorithm. This paper proposes a YOLOv4-tiny mask detection algorithm with an attention mechanism for complex and changeable situations and small-scale target detection. The algorithm comprises the following steps. First, a hybrid domain attention mechanism CBAM is added to the feature map output by the backbone network as the input of the feature fusion network so that the network pays more attention to the effective area of the sample during training. Second, the Mosaic data enhancement method enriches the data so the model can learn global and local features better. Moreover, the learning rate cosine annealing attenuation strategy is used in training to accelerate the convergence of the model. In this paper, 5983 images are selected from WIDER Face and MAFA data sets to form a face mask data set for training and testing of the algorithm. The experimental results show that the map of the model can reach 85.21 %, the model parameters are small, and the detection speed can reach 87.79 FPS. Therefore, it is convenient for people to deploy it on mobile devices and realize real-time detection.

When conducting text sentiment analysis based on traditional deep learning models, lack of extracting deep-seated characteristics and sentence system characteristics etc. The article propose a model based on improving capsule networks. This model uses Weibo text as the research object, and uses BERT to obtain the word vector; then use CNN to extract deep phrase characteristics, LSTM networks to model the dependencies of each word in the instance, and dig out its hidden semantics; then increase attention layer is screened with effective features; finally, the improved capsule network is used to express a richer expression of text sentiment information to enhance the overall abstraction capabilities of the model. After experimenting on the dataset, it achieved good results on Weibo's sentiment analysis. The result shows that the model is better than traditional models, and it also fully shows that the model can effectively improve the accuracy of sentiment analysis.

Cybersecurity is a prerequisite for maritime safety. This study focuses on intelligent ship integrated automation system, analyzing the principles and shortcomings of these system. We propose a machine learning-based intrusion detection solution that utilizes Recursive Feature Elimination (RFE) as a feature selection algorithm and XGBoost as a classification algorithm. The Bayesian optimization algorithm is applied to optimize the hyperparameters of the XGBoost model for detecting anomalous network data. Results indicate that, compared to decision trees, logistic regression, random forests, KNN, and recent research findings, the proposed method exhibits smaller estimation errors with an overall accuracy of 99.8%. It effectively reduces vulnerabilities in ship networks, achieving a F1-score of 96.37% and a recall rate of 96.33% under sufficient dataset conditions. This approach enhances network security performance and elevates the cybersecurity level of intelligent ships.

As a nondestructive testing technique, the isothermal relaxation current (IRC) method has been applied to assess the condition of power cable insulation. In order to shorten the detection time in the field and improve the measurement accuracy, a modified measurement circuit based on an independent measurement loop was proposed to discharge the interference from the high-voltage insulated wires. Based on this circuit, the three-phase synchronous IRC measurement system was established. Furthermore, the independence and consistency of the three-phase current measurement loop were verified, which could realize the synchronous acquisition of the three-phase relaxation current. Finally, the three-phase IRC test was carried out to evaluate the aging state of the sample in service. The results showed that the aging state of each phase for the same cable might be quite different after long service.

Intelligent control system (ICS) is a new type of control system that combines advanced intelligent control technologies, such as big data and artificial intelligence, with traditional DCS, and it is the development direction of realizing production process intelligence in thermal power plants. In this paper, for the third-party intelligent applications other than DCS manufacturers, and in view of the deficiencies of existing intelligent control systems in terms of integration and extensibility, we propose a general intelligent control platform architecture design based on "microservices + containerization" and "unified interface + modularization". The platform integrates DCS internal communication interface and human-computer interaction interface, realizes the integrated monitoring and closed-loop control of general intelligent control platform and DCS, and is compatible with a variety of DCS and intelligent applications developed in different programming languages. The successful on-line operation of the general intelligent control platform on a 600MW unit of a power plant has verified the rationality and effectiveness of the system architecture design.
