Array signal processing is an important branch in the field of signal processing. It has been widely used in many military and national economic fields such as radar, communications, sonar, navigation, voice signal processing, seismic monitoring, and biomedical engineering. Adaptive beamforming is an important research content in array signal processing. It is essential to perform spatial filtering through adaptive weighting of each array element to achieve the purpose of enhancing the desired signal, suppressing interference and reducing noise signals. Minimum variance distortion response (MVDR) is a commonly used algorithm. It restricts the array gain to 1 in the desired signal direction and minimizes the output power of the array to achieve the purpose of suppressing interference. However, in real-life environment, most processing speech system are affected by various types of noise, like coherence, incoherence, diffuse and ambient noise. These unwanted factors strong degrade performance of designed system. The quality and intelligibility, which one of the most important measurement of output signal, decreases when surrounding environment is too complex. In this paper, the author proposed an improved technology to enhance algorithm MVDR in diffuse noise field. The results illustrated that, the suggested algorithm allowed reducing speech distortion from 5.1÷15.5 (dB). The promising method can be further combined with many speech applications. © 2022 IEEE.

A growing number of human-centric tasks like learning, planning, and creative writing require the integration of Artificial Intelligence (AI) in the current era of exponential advancements. Such systems collect and analyze data on their own making the best use of available resources and providing creative solutions for challenging issues. The impact of AI on productivity, data analysis, flexibility, and real-time decision- making in a variety of fields is examined in this paper. Focusing on academic settings, the paper considers ethical concerns surrounding AI-generated content. According to a survey, even though many students use ChatGPT for writing and research, worries about academic integrity and plagiarism still exist.

The report proposes a dynamic routing method for Self-healing Networks (ShN). The method takes into account the specific features of ShN. During routing, the flow of service information is reduced. The search for the optimal route is carried out using a convolutional neural network. The method significantly outperforms existing methods when some network nodes fail. ©2024 IEEE.

In this paper, a Safety System-on-Chip based on the open-source RISC-V processor SweRV EH1 from Western Digital is presented. A hardware comparator concept is followed. The SSoC is implemented on a Xilinx FPGA system and extended with standard peripherals from the Xilinx IP library and from Cobham Gaisler, so that the overall system has an Ethernet interface in addition to GPIO and UART. The goal is to create a complete redundancy approach with a hardware fault tolerance of nearly 1 from input to output based on the freely available RISC-V instruction set and prove its feasibility. © 2022 The authors and IOS Press.

Speech is a natural way of communicating between human beings and as such, it triggers an interest of transforming it to a way of interaction with a computer as well. Once it is converted into a sequence of words, it can easily be applied for executing commands, thus enabling people to perform tasks easily or in some cases - tasks that are even impossible for them to be performed. The automatic speech recognition becomes a task solved with various success based on the accuracy, online/offline availability, speed. However, with the constant improvement of the neural networks, it is getting easier to solve and the most prominent solution seems to be the Transformer architecture of neural networks. In this paper, we describe the design of an encoder-decoder TensorFlow architecture and the process of training the model with a specially created Bulgarian dataset. © 2021 IEEE.

The article proposes a method of zero-watermarking for colored RGB bitmap images. This algorithm can be used to protect property rights to multimedia resources in which it is impossible to use ordinary watermarks due to the impossibility of changing the image (such as medical data where high accuracy is required and the appearance of artifacts is unacceptable) or due to the presence of a higher distortion of the container. This algorithm is based on DWT, SVD and operations in the field by modulo 256. The software implementation of the algorithm was developed (using the Accord and *** libraries to implement DWT, SVD). The software implementation of the algorithm was tested. This algorithm has advantages in the form of normalization of the average error, but it needs further research to improve its performance.

The Matura exam is the final national examination that high school students in many countries must pass to be eligible for admission to a university. This paper discusses the key factors that have the most impact in producing a reliable machine learning model for predicting students' enrollment in the university. These factors include the final grades from each high school year, matura exam results and the university entry exam points. It should be noted that demographic factors were not taken into consideration in this study. Four machine learning (ML) techniques with a total of sixteen algorithms were implemented using the Weka software: Bayes (Bayes Net, Naive Bayes, etc.), Logistic Regression (Logistic and SimpleLogistic), K-Nearest Neighbors (IBK, KStar, and LWL) and Decision Tree (J48, Random Forest, RepTree, etc.). According to the results, The RepTree algorithm performed the best with a True Positive (TP) rate of 0.902 and a False Positive (FP) rate of 0.148. The algorithm with the lowest performance was NaiveMulti with a TP rate of only 0.790. However, the range between the worst and the best-performing algorithms was 14.18%. © 2021 IEEE.

Chinese Journal of Electronics 2023年第2期19卷 211-216页

作者： Xiaohua Shi Gansha Wu Jin Maozhong Guei-Yuan Lueh School of Computer Science Beihang University Beijing China Programming System Laboratory Microprocessor Technology Labs Intel Corporation Beijing China

This paper introduced the optimization and deoptimization technologies for Escape analysis in open world. These technologies are used in a novel Escape analysis framework that has been implemented in Open runtime platform, Intel's open-source Java virtual machine. We introduced the optimization technologies for synchronization removal and object stack allocation, as well as the runtime deoptimization and compensation work. The deoptimization and compensation technologies are crucial for a practical Escape analysis in open world. We evaluated the runtime efficiency of the deoptimization and compensation work on benchmarks like SPECjbb2000 and SPECjvm98.

In this paper, we explored approaches that improve the performance of ensemble bagging classifiers for identifying the state of a computer system. The following algorithms are considered: Ensemble pruning, Advanced Voting Algorithms, Dynamic Voting Strategies, Confidence Calibration, Adaptation through Meta-Features and Meta-Learning, which allow improving the voting procedure of the bagging meta-algorithm. Artificial data was generated as initial data, which complicates the classification task and contains an increased amount of noise. In the Google Collab environment, software models of algorithms have been developed, and their quality has been assessed. It was found that the use of the Ensemble pruning and Adaptation through Meta-Features algorithm is the most qualitative. In addition, the Ensemble pruning algorithm reduces the number of basic ensemble classifiers, and, as a result, increases the efficiency of computer system identification. Based on the results of the study, a method for identifying a computer system was proposed through the integrated use of a bagging classifier and an optimization procedure based on the Ensemble pruning algorithm.
