In recent years, the butterfly optimization algorithm (BOA) has attracted a lot of attention because of its precise balance mechanism between exploitation and exploration. However, due to the shortcomings such as insufficient accuracy and slow convergence speed, the practical application of BOA is limited to a certain extent. This paper has two main contributions: 1) An elite-based butterfly optimization algorithm (eBOA) is proposed, which introduces an elite subgroup and gives full play to the positive role of elite elements in evolution. eBOA uses the optimal butterfly and the random elite butterfly to intervene in the global and local search operators respectively, thereby guiding the population to evolve in a more potential direction. Then, eBOA superimposes an existing parameter as a weight on the basis vector of the global search operator to speed up the convergence. 2) A preprocessing method for speckle images and disparity data that can be used in deep learning is proposed, and a novel 3D speckle reconstruction method is generated by combining eBOA with a deep network. In terms of results, comparative experiments based on 20 benchmark functions and 7 advanced meta-heuristic algorithms show that eBOA has excellent optimization capability;The comparison experiments of 5 deep networks confirm that the new reconstruction method can significantly improve the accuracy of speckle reconstruction models, and once again verify the remarkable optimization performance of eBOA.

Real-world problems are complex as they are multidimensional and multimodal in nature that encourages computer scientists to develop better and efficient problem-solving methods. Nature-inspired metaheuristics have shown better performances than that of traditional approaches. Till date, researchers have presented and experimented with various nature-inspired metaheuristic algorithms to handle various search problems. This paper introduces a new nature-inspired algorithm, namely butterfly optimization algorithm (BOA) that mimics food search and mating behavior of butterflies, to solve global optimization problems. The framework is mainly based on the foraging strategy of butterflies, which utilize their sense of smell to determine the location of nectar or mating partner. In this paper, the proposed algorithm is tested and validated on a set of 30 benchmark test functions and its performance is compared with other metaheuristic algorithms. BOA is also employed to solve three classical engineering problems (spring design, welded beam design, and gear train design). Results indicate that the proposed BOA is more efficient than other metaheuristic algorithms.

Because of dust, trees, high buildings in the surrounding area, partial shading conditions (PSC) occur in photovoltaic (PV) systems. This condition affects the power output of the PV system. Under PSC there is a global maximum power point (GMPP) besides there are a few local maximum power points (LMPP). This condition makes the maximum power point tracking (MPPT) procedure a challenging task. In order to solve this issue, soft computing techniques such as gray wolf optimization (GWO), particle swarm optimization (PSO) and Gravitational Search algorithm (GSA) are implemented. However, the performance of MPP trackers still needs to be improved. The main contribution of this paper is improving the tracking speed by implementing BOA to the MPPT of the PV system under PSC. Thus, in real-time applications a promising alternative presented to the literature to improve the performance of the PV systems under variable PSC because of its fast tracking speed. PV system consists of PV array, boost converter and load are modeled and simulated in MATLAB/Simulink. BOA algorithm is implemented for three different insolation scenarios on the PV array. The results of the BOA algorithm verified by a comparative analysis with PSO-GSA and GWO algorithms. The results show that BOA can give high accuracy and better tracking speed than these algorithms in recent literature.

Cognitive radio (CR) is the best candidate for the growing demands of wireless connectivity in the internet of things (IoT). In the CR network, sensing performance is enhanced through cooperative spectrum sensing (CSS). However, security issues in CSS are to be tackled for reliable sensing. The malicious users (MUs) threaten the spectrum sensing that forward false sensing information to the fusion center (FC). To this end, this paper proposes an optimum CSS employing a penalty-reward-based butterfly optimization algorithm (PRBOA). The optimum coefficient vector enables FC to degrade the sensing notifications of the different categories of MUs in contrast with the normal secondary users (SUs). The coefficient vector and threshold are employed in the soft decision fusion to produce the global decision at the FC. A novel penalty-reward scheme is introduced in this work that assigns a penalty to the reports of MUs and rewards the normal SUs. The PRBOA scheme proposed in this work shows improved sensing results.

In this article, a new maximum power point tracking algorithm based on a modified butterfly optimization algorithm has been proposed. The proposed method is capable of differentiating between different partial shading patterns, uniform shading, solar intensity, and load variation conditions with fast convergence speed (CS). Only one dynamic variable is used as a tuning parameter reducing the complexity of the algorithm. The search space skipping method has been proposed to improve the CS. The proposed method is hybridized with a constant impedance method to improve the response time of the system for fast varying load variations. The proposed method has been validated experimentally on the SEPIC converter topology with a sampling time of 0.05 s. The experimental validation proved the average tracking time for different shading patterns is less than 1 s with steady-state efficiency of 99.85% on average. The CS for uniform shading conditions is improved by 47.20%. The response to load variation is also improved by 86.15% and becomes eligible to be utilized for fast varying load variations. Finally, the comparison table based on the MPPT rating has been presented to determine the effectiveness of the proposed method among other popular metaheuristic approaches used for MPPT.

Network intrusion detection systems analyze traffic in a medical IoT system to detect abnormal behaviors. Machine learning and artificial intelligence (AI) algorithms are widely used in designing intrusion detection systems to prevent attacks on a medical IoT system. In this paper, an artificial neural network is employed to detect abnormal behavior in a medical IoT system. The accuracy of the detection depends heavily on the features that are fed into the artificial neural network. Selecting the important and discriminative features of network traffic is a crucial and challenging issue because it has a significant impact on the learning process. In the proposed method, the butterfly optimization algorithm which is a meta-heuristic optimization algorithm is employed to select the optimal features for the learning process in an artificial neural network. The results achieved, 93.27% accuracy, indicate the capability of the butterfly optimization algorithm to determine discriminative features of network traffic data. The proposed algorithm outperformed the decision tree, support vector machine, and ant colony optimization, which was proposed in previous researches for the same goal.

MULTIMEDIA TOOLS AND APPLICATIONS 2024年第30期83卷 73817-73839页

Speaker recognition is extensively applied in several applications, namely identity verification, electronic voice eavesdropping, surveillance, voice recognition, etc. In an effective speaker recognition system, the extraction and selection of salient and discriminative features is an essential process for accurately identifying the speakers. Therefore, a novel hybrid framework is introduced in this research manuscript. Initially, the input data are acquired from the three-benchmark databases: THUYG-20 SRE corpus, Ryerson Audio-Visual Database of Emotional Speech and Song (RAVDESS), and LibriSpeech. Further, the emotional features are extracted by utilizing hybrid feature extraction techniques which are, amplitude, zero cross rate, energy, Root Mean Square (RMS), statistical moments, autocorrelation, and Mel-Frequency Cepstral Coefficients (MFCC). Then, the feature optimization is carried out using Improved butterfly optimization algorithm (IBOA) that decreases the computational time and complexity of the recognition model. At last, a hybrid classifier: Convolutional Neural Network (CNN) with Long Short Term Memory (LSTM) is implemented for speaker recognition, and its performance is analyzed in terms of F1-score, specificity, accuracy, Positive Predictive Value (PPV), and sensitivity. The empirical investigation demonstrated that the IBOA-based hybrid LSTM network achieved 92.65%, 96.97% and 96.98% of recognition accuracy on the LibriSpeech, RAVDESS and THUYG-20 SRE corpus databases. These results are more impressive than the comparative models, Deep Neural Network (DNN), random forest, K-Nearest Neighbor (KNN), LSTM, Multi class Support Vector Machine (MSVM), Deep Convolutional Recurrent Neural Network (DCRNN), Golden Ratio aided Neural Network (GRaNN), deep sequential LSTM, and Probabilistic Neural Network (PNN).
