weak orthogonal matching pursue algorithm cannot obtain high-precision reconstructed signals in the measurement process. Thus, this study proposes an improved SWOMP algorithm called DHP-SWOMP, which is based on partial Hadamard matrix, to overcome the aforementioned shortcoming. First, Dice coefficient matching is introduced to effectively distinguish the atomic correlation and ensure the selection of the best atom for overcoming the similar atom selection in traditional SWOMP algorithm. Then, the sampling partial Hadamard matrix is proposed as the measurement matrix to overcome the issue of failing to obtain high-precision reconstructed signals when Gaussian matrix is used in SWOMP algorithm. The random independence of the matrix is used to improve the reconstruction accuracy of the algorithm. Simulation results show that the proposed algorithm improves the signal-to-noise ratio by 53.97%, shortens the reconstruction time by 87.60%, reduces the mean square error by 15.46%, and have smaller recovery residual and higher signal reconstruction rate than SWOMP algorithm based on Gaussian matrix.

This paper investigates the problem of stability for neutral-type memristive neural networks (NMNN s) with uncertainties satisfying Lipschitz condition. The technology for dynamic quantization control input is suggested, which can reduce the burden of digital communication by utilizing quantization input. Introducing dynamic quantization parameters effectively avoids quantization saturation phenomenon. Then, using the Lyapunov- Krasovskii functional (LKF) theory and integral inequality, to assure the system's stability, new sufficient conditions are recommended. Through the analysis of the viability of solving linear matrix inequalities (LMIs), we derived the feedback gain matrix and determined a new range for the dynamic quantization parameter. Finally, we provide one numerical example with simulations to validate the usefulness of our proposed theoretical results.

The surge in computervision applications has amplified the need for precise and resilient car classification systems. Addressing this, our research delves into enhancing the accuracy and adaptability of systems classifying four car types: Audi, Mahindra Scorpio, Swift, and Tata Safari. Our approach used a rich training dataset of carefully curated and annotated images representing the targeted car categories, coupled with a validation dataset for model refinement. Utilizing the YOLOv8 deep learning model, we embarked on rigorous training and validation phases. A key emphasis was on combating overfitting, ensuring our model's wider applicability. Our efforts culminated in a commendable 91 % accuracy. This paper offers a gamut of insights: illustrative charts, detailed outcomes, and a thorough dissection of the confusion matrix. Our results highlight YOLOv8's prowess in car classification and its promise in bolstering object recognition systems, all while adeptly navigating overfitting challenges.

In order to fully explore the time-series correlation of power load data and improve the prediction accuracy of power load, this paper proposes a neural network-based deep learning approach for power load prediction. Firstly, the relevant electric power data are obtained and divided into appropriate sample sizes, and the samples are normalized; then, a prediction model based on LSTM is built to explore the correlation between different features, and the corresponding model of this neural network is further trained and validated on the data test set; finally, a comparison between LSTM and other algorithms such as SVM, ANN, GAOS and GM are performed. The results show that the LSTM prediction algorithm can better track the trend of power load change, with higher prediction accuracy and efficiency.

Falls among the elderly population present significant risks, including serious injuries and even death. Prompt detection of falls is crucial for immediate assistance and notification to relevant parties. However, current fall detection systems face challenges and privacy concerns. To address this, a new system is proposed using a Convolutional Neural Network (CNN) and optimizing Optical Flow images through preprocessing in spatial and frequency domains. The system incorporates the Viola-Jones algorithm for human face and action recognition. It is designed for detecting falls in home or room environments, covering various postures - standing, sitting, walking, and falling. Surveillance cameras in public spaces capture relevant data for training the model. The system achieves impressive accuracy and precision, highlighting its effectiveness in fall detection applications.
