However, its performance can degrade in the presence of modeling errors and uncertainties in the system dynamics. To enhance the robustness and accuracy of the Kalman filter, the concept of a Fading-Memory Kalman Filter (FMKF) has been introduced. The FMKF incorporates a fading-memory mechanism that effectively mitigates the impact of modeling errors and reduces permanent estimation errors. By assigning time-varying weights to past measurements and predictions, the FMKF adaptively adjusts its influence on the current state estimation. This mechanism allows the FMKF to better accommodate dynamic system behavior and parameter changes. In this paper, the effectiveness of the FMKF is evaluated by comparing it with the standard Kalman filter. The performance of both filters is assessed in scenarios where modeling errors are present, and parameter variations occur. The results demonstrate that the FMKF outperforms the standard Kalman filter by providing more accurate and robust state estimates, even in the presence of modeling errors. The FMKF's ability to adaptively update the weights based on the relevance of past information allows it to effectively handle dynamic system behavior and changing parameters.

On the other hand, the clustering of important genetic data, which often have high dimensions, faces many limitations using traditional methods. In the current work, a new semi-supervised ensemble spectral clustering (EPLSC) algorithm based on the graph p-Laplacian for genetic data is introduced. In the proposed approach, we first propagate the pairwise must-linked as well as cannot-linked constraints on all data. Then the feature space is randomly split into various unequal subspaces. Using the updated pairwise constraints, semi-supervised spectral clustering is performed in each subspace independently. Then, using the results of each one, an adjacency matrix is created based on ensemble learning. Next, by using several search operators in environments composed of different subspaces, the best set of subspaces is obtained. Experimental validation on 15 high-dimensional genetic datasets demonstrates that EPLSC outperforms existing methods, achieving improvements of up to 18% in Normalized Mutual Information (NMI) and 15% in Adjusted Rand Index (ARI) compared to traditional semi-supervised techniques. This indicates that EPLSC not only enhances clustering efficacy but also effectively addresses the unique challenges posed by genetic data.

These emails, sent in bulk for commercial and malicious purposes, can bypass traditional spam filters, necessitating the development of high-accuracy models for effective detection. A major challenge in spam filtering is reducing false positives, which can lead to legitimate emails being incorrectly classified as spam, impacting users' email communication. In this study, deep learning (DL) and natural language processing (NLP) methods were employed to develop a spam detection model. Five DL-based models—Dense, CNN, LSTM, CNN-LSTM, and BERT—were evaluated. Data preprocessing included stemming, lemmatization, and text vectorization using Word2Vec to enhance feature extraction. The models were trained on a real dataset, and their accuracy was assessed using multiple evaluation indices. The findings demonstrated that, among the tested models, BERT achieved the highest accuracy (99.33%), outperforming all other approaches in spam detection. Its ability to understand contextual relationships and mitigate false positives makes it highly suitable for real-world applications. Given its computational demands, future research should focus on optimizing BERT for real-time deployment through model compression and parallel execution. Additionally, further testing on larger and more diverse datasets and implementing multilingual spam filtering capabilities will enhance its practical utility.

In three-phase systems, using three-phase conversion to the synchronous reference frame, linear controllers can be easily used to control the inverter due to the conversion of AC parameters in the synchronous frame to dc components. The design of linear controllers in single-phase systems is often difficult because of the oscillating nature of these systems. In some cases, single-phase conversion to synchronous frame is used, which has its problems, such as delays in converting single-phase values to two-phase. To tackle this problem, proportional-resonance (PR) instruments can be used at a specific resonant frequency. However, for single-phase systems where all the harmonies are present in the inverter current, an unlimited number of PR instruments are required. Therefore, not all harmonies can be controlled in this way. To overcome this, a iterative control system can be used. The control method presented in this paper uses delay intervals with positive feedback. Under these conditions, the control gain in the dynamic model of the iterative control system is very high for all harmonies and allows tracking the reference current and voltage values with a zero steady-state error in all harmonies. In addition, the performance of the iterative control system in the face of single-phase systems will be very favorable.

A major challenge in spam filtering is reducing false positives, which can lead to legitimate emails being incorrectly classified as spam, impacting users' email communication. In this study, deep learning (DL) and natural language processing (NLP) methods were employed to develop a spam detection model. Five DL-based models—Dense, CNN, LSTM, CNN-LSTM, and BERT—were evaluated. Data preprocessing included stemming, lemmatization, and text vectorization using Word2Vec to enhance feature extraction. The models were trained on a real dataset, and their accuracy was assessed using multiple evaluation indices. The findings demonstrated that, among the tested models, BERT achieved the highest accuracy (99.33%), outperforming all other approaches in spam detection. Its ability to understand contextual relationships and mitigate false positives makes it highly suitable for real-world applications. Given its computational demands, future research should focus on optimizing BERT for real-time deployment through model compression and parallel execution. Additionally, further testing on larger and more diverse datasets and implementing multilingual spam filtering capabilities will enhance its practical utility.

In three-phase systems, using three-phase conversion to the synchronous reference frame, linear controllers can be easily used to control the inverter due to the conversion of AC parameters in the synchronous frame to dc components. The design of linear controllers in single-phase systems is often difficult because of the oscillating nature of these systems. In some cases, single-phase conversion to synchronous frame is used, which has its problems, such as delays in converting single-phase values to two-phase. To tackle this problem, proportional-resonance (PR) instruments can be used at a specific resonant frequency. However, for single-phase systems where all the harmonies are present in the inverter current, an unlimited number of PR instruments are required. Therefore, not all harmonies can be controlled in this way. To overcome this, a iterative control system can be used. The control method presented in this paper uses delay intervals with positive feedback. Under these conditions, the control gain in the dynamic model of the iterative control system is very high for all harmonies and allows tracking the reference current and voltage values with a zero steady-state error in all harmonies. In addition, the performance of the iterative control system in the face of single-phase systems will be very favorable.
