Hybrid Artificial Intelligence Model for Reliable Decision Making in Power Transformer Maintenance Through Performance Index Vinícius Faria Costa Mendanha, André Pereira Marques, Lucas Santos de Aguiar, Juliermy Junio Pacheco dos Santos, Álisson Assis Cardoso, et al. Energies, 2025 The preventive maintenance of power transformers is essential to ensure their reliability and is supported by efficient predictive techniques and accurate diagnostics. In this context, the objective of this work is to present a hybrid Artificial Intelligence (AI) model for reliable decision making in transformer maintenance based on performance index monitoring. The innovation lies in the application of Monte Carlo filters to monitor the operational state of transformers combined with a novel clustering strategy. The used methodology includes the development of an algorithm for outlier removal in the historical series of each predictive technique as well as the implementation of stochastic filters to forecast the overall operational condition. The results demonstrate the robustness and effectiveness of the developed model. This work contributes a new AI-based strategy for supporting preventive maintenance decisions, enabling precise and individualized actions for each piece of equipment, with broad applicability to companies in the electrical power sector.
Two-Stage Dimensionality Reduction for Social Media Engagement Classification Jose Luis Vieira Sobrinho, Flavio Henrique Teles Vieira, Alisson Assis Cardoso Applied Sciences Switzerland, 2024 The high dimensionality of real-life datasets is one of the biggest challenges in the machine learning field. Due to the increased need for computational resources, the higher the dimension of the input data is, the more difficult the learning task will be—a phenomenon commonly referred to as the curse of dimensionality. Laying the paper’s foundation based on this premise, we propose a two-stage dimensionality reduction (TSDR) method for data classification. The first stage extracts high-quality features to a new subset by maximizing the pairwise separation probability, with the aim of avoiding overlap between individuals from different classes that are close to one another, also known as the class masking problem. The second stage takes the previous resulting subset and transforms it into a reduced final space in a way that maximizes the distance between the cluster centers of different classes while also minimizing the dispersion of instances within the same class. Hence, the second stage aims to improve the accuracy of the succeeding classifier by lowering its sensitivity to an imbalanced distribution of instances between different classes. Experiments on benchmark and social media datasets show how promising the proposed method is over some well-established algorithms, especially regarding social media engagement classification.
Resource scheduling scheme for 5G mmWave CP-OFDM based wireless networks with delay and power allocation optimizations Marcus Vinícius G. Ferreira, Flávio H. T. Vieira, Alisson A. Cardoso ETRI Journal, 2023 In this paper, to optimize the average delay and power allocation (PA) for system users, we propose a resource scheduling scheme for wireless networks based on Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP‐OFDM) according to the first fifth‐generation standards. For delay minimization, we solve a throughput maximization problem that considers CP‐OFDM systems with carrier aggregation (CA). Regarding PA, we consider an approach that involves maximizing goodput using an effective signal‐to‐noise ratio. An algorithm for jointly solving delay minimization through computation of required user rates and optimizing the power allocated to users is proposed to compose the resource allocation approach. In wireless network simulations, we consider a scenario with the following capabilities: CA, 256‐Quadrature Amplitude Modulation, millimeter waves above 6 GHz, and a radio frame structure with 120 KHz spacing between the subcarriers. The performance of the proposed resource allocation algorithm is evaluated and compared with those of other algorithms from the literature using computational simulations in terms of various Quality of Service parameters, such as the throughput, delay, fairness index, and loss rate.
