This study proposes a new prairie dog optimization algorithm version called EPDO. This new version aims to address the issues of premature convergence and slow convergence that were observed in the original PDO algorithm. To improve performance, several modifications are introduced in EPDO. First, a dynamic opposite learning strategy is employed to increase the diversity of the population and prevent premature convergence. This strategy helps the algorithm avoid falling into local optima and promotes global optimization. Additionally, the Lévy dynamic random walk technique is utilized in EPDO. This modified Lévy flight with random walk reduces the algorithm’s running time for the test function’s ideal value, accelerating its convergence. The proposed approach is evaluated using 33 benchmark problems from CEC 2017 and compared against seven other comparative techniques: GWO, MFO, ALO, WOA, DA, SCA, and RSA. Numerical results demonstrate that EPDO produces good outcomes and performs well in solving benchmark problems. To further validate the results and assess reliability, the authors employ average rank tests, the measurement of alternatives, and ranking according to the compromise solution (MARCOS) method, as well as a convergence report of EPDO and other algorithms. Furthermore, the effectiveness of the EPDO algorithm is demonstrated by applying it to five design problems. The results indicate that EPDO achieves impressive outcomes and proves its capability to address practical issues. The algorithm performs well in solving benchmark and practical design problems, as supported by the numerical results and validation methods used in the study. © The Author(s) 2024.

Unsupervised function getting to know for image segmentation is a method of utilizing machine learning algorithms to identify the features of an image that can be maximum appropriate for segmentation responsibilities without requiring any previously classified statistics. By using the usage of clustering algorithms together with k-way or Self-Organizing Maps, the set of rules is capable of extracting specific capabilities from the picture and grouping patterns or objects into separate clusters. Those clusters can then be used to identify the specific additives within the picture and reap a segmentation result. This approach has been mainly useful for segmenting herbal pix, where the capabilities of the gadgets aren't without problems manually described because of the complex and varied nature of the records. Furthermore, it's been proven to achieve advanced accuracy in comparison to standard rule-based segmentation strategies. © 2024 IEEE.

IEEE Transactions on Transportation Electrification 2025年

This paper proposed a robust model predictive control for permanent magnet synchronous motors taking into account the effect of disturbance. A structure cascading extended Kalman filter (EKF) and linear extended state observer (LESO) is used to estimate the position of the motor without using encoders. Firstly, the voltage vector reference containing information of the system speed and current are predicted using the deadbeat control. Meanwhile, the ultra-local model of the system is built considering the lumped disturbance of the motor. The disturbed part of the ultra-local model is updated online according to the information of voltage and current in past two moments. Then, a cascaded EKF-LESO is designed to efficiently estimate position and speed, taking into account disturbances such as measurement noise and model parameter uncertainty. Experimental results verify the effectiveness and advantages of the proposed method. © 2015 IEEE.

The identification and categorization of soiling using artificial intelligence is essential for improving solar photovoltaic (PV) system efficiency. It is possible to use focused and effective cleaning techniques on solar panels by classifying and comprehending the particular types of pollutants. This research proposes a modified convolutional neural network (CNN) approach to efficiently classify soiling on solar PV panels. In contrast to the conventional method, the suggested CNN model is created using simple images rather than images plus time series data. As a result, processing speed is increased. Additionally, the suggested model achieved 96.91 percent accuracy. This success establishes our suggested methodology as a ground-breaking development in soiling type detection, providing improved accuracy and a unique strategy in contrast to current approaches. The trained and tested model is deployed on the web using the Flask. Flask is a powerful and flexible microweb framework for Python, Finally, a comparison is made between the existing method and the proposed method. © 2024 IEEE.

This paper studies the Partial Optimal Transport (POT) problem between two unbalanced measures with at most n supports and its applications in various AI tasks such as color transfer or domain adaptation. There is hence a need for fast approximations of POT with increasingly large problem sizes in arising applications. We first theoretically and experimentally investigate the infeasibility of the state-of-the-art Sinkhorn algorithm for POT, which consequently degrades its qualitative performance in real world applications like point-cloud registration. To this end, we propose a novel rounding algorithm for POT, and then provide a feasible Sinkhorn procedure with a revised computation complexity of Oe(n2/Ε4). Our rounding algorithm also permits the development of two first-order methods to approximate the POT problem. The first algorithm, Adaptive Primal-Dual Accelerated Gradient Descent (APDAGD), finds an Ε-approximate solution to the POT problem in Oe(n2.5/Ε). The second method, Dual Extrapolation, achieves the computation complexity of Oe(n2/Ε), thereby being the best in the literature. We further demonstrate the flexibility of POT compared to standard OT as well as the practicality of our algorithms on real applications where two marginal distributions are unbalanced.
