Recent medical research has significantly emphasized the need for early illness diagnosis due to the fast rise of the world's population. Since there are now more people in the world, the danger of dying from breast cancer is rising at an exponential rate. Breast cancer is currently the second deadliest form of cancer out of all the forms that are known. When it comes to illness diagnosis, having access to an automated disease detection system is very helpful to medical professionals since it enables them to provide dependable, effective, and quick reactions while also lowering the mortality rate. This research assesses the hybridization of two deep learning models, a convolutional neural network (CNN) and an artificial neural network (ANN) - the well-known BreakHis_v1_400X dataset (a dataset for breast cancer histopathological images) to work with. The performance of these approaches is evaluated based on several criteria, including accuracy, sensitivity, specificity, precision, false-positive rate, and F1 score. In addition, we evaluate these methods by calculating the area under the curve for accuracy and recall, as well as the receiver operating characteristic curve. According to the findings, the hybridized CNN-ANN achieved the most remarkable accuracy, precision, AUC, and F1 score, with respective values of 89.47%, 86.18%, 89.46%, and 89.08%. © 2024 IEEE.

This paper presents an application of a mixture of Hidden Markov Models (HMMs) as a tool for verification of IoT fuel sensors. The IoT fuel sensors report the level of fuel in tanks of a petrol station, and are a key component for monitoring system reliability (billing), safety (fuel/oil leak detection) and security (theft prevention). We propose an algorithm for learning a mixture of HMMs based on a continual learning principle, i.e. it adapts the model while monitoring a sensor over time, signalling unexpected or anomalous sensor reports. We have tested the proposed approach on a real-life data of 15 fuel tanks being monitored with the FuelPrime system, where it has shown a very good performance (average area under ROC curve of 0.94) of detecting anomalies in the sensor data. Additionally we show that the proposed method can be used for trend monitoring and present qualitative analysis of the short and long term learning performance. The proposed method has promising performance score, the resulting model has a high degree of explainability, limited memory and computation requirements and can be easily generalized to other domains of sensor verification. © 2023 Polish Information Processing Society.

A technology is proposed for estimating the probability that a share price will fall below the minimum level. The exact expression is obtained for the required probability under the assumption that the behavior of the share price is described by the well-known model of Samuelson, according to which the relative change in price is the sum of the non-random trend and the Wiener process. The obtained result is qualitatively analyzed for various relations of the problem parameters. © 2023 IEEE.

This study provides insights into SLAM performance on embedded systems and introduces an unsupervised parameter tuning approach for enhanced localisation accuracy. Our paper benchmarks a ROS 2-based indirect Simultaneous Localisation and Mapping (SLAM) system across six NVIDIA Jetson devices: Orin Nano 4 GB, Orin Nano 8 GB, Orin NX 8 GB, Orin NX 16 GB, AGX Orin 32 GB Auvidea, and AGX Orin 32 GB Devkit, using sequences from the KITTI dataset. The edge devices differ significantly in GPU computing power, number of CPU cores, CPU clock frequency as well as memory. SLAM evaluations are conducted within Docker containers to ensure consistency, with feature detection parameters optimised using an unsupervised tuning approach for each device. In addition to localisation accuracy, hardware utilisation is analysed, revealing that less than a half of CPU capabilities and approximately 5– 10 % of GPU power are utilised. The results indicate that in the default configuration devices with lower computing power demonstrate higher fluctuation in SLAM localisation accuracy. However, optimising feature parameters improves accuracy stability, especially for less powerful edge devices, indicating that even lower-powered but more energy-saving devices can achieve similar performance when an optimised balance between feature quantity and runtime constraints is achieved.

In recent years, face recognition systems have faced increasingly security threats, making it essential to employ Face Anti-spoofing (FAS) to protect against various types of attacks in traditional scenarios like phone unlocking, face payment and self-service security inspection. However, further exploration is required to fully secure FAS in long-distance settings. In this paper, we propose two contributions to enhance the security of face recognition systems: Dynamic Feature Queue (DFQ) and Progressive Training Strategy (PTS). DFQ converts the conventional binary classification task into a multi-classification task. It treats live samples as a closed set and attack samples as an open set by using a dynamic queue that stores the features of spoofing samples and updates them. On the other hand, PTS targets difficult samples and iteratively adds them in batches for training. The proposed PTS divides the entire training set into blocks, trains only a small portion of the data, and gradually increases the training data with each stage while also incorporating low-scoring positive samples and high-scoring spoof samples from the test set. These two contributions complement each other by enhancing the model’s ability to generalize and defend against various types of attacks, making the face recognition system more secure and reliable. Our proposed methods have achieved top performance on ACER metric with 4.73% on the SuHiFiMask dataset [11] and won the first prize in Surveillance Face Anti-spoofing track of the Challenge@CVPR 2023.

Wildfires not only pose a significant threat to human life and property but also have far-reaching impacts on communities and ecosystems. Effective prevention and mitigation strategies rely on accurate prediction of the path of these fires. This paper proposes the utilization of data obtained from Unmanned Aerial Vehicles (UAVs) to develop predictive models for fire spread. A comprehensive dataset is presented that includes key environmental variables that have been meticulously captured using these advanced technologies. The dataset comprises images from which essential features for predicting fire spread have been extracted. The method detailed in this article has been used to identify and incorporate crucial factors such as plant density, wind direction and speed, humidity, and geographical features. These key factors are then used to predict the spread of fires using Machine Learning (ML) techniques. After thorough study and comparison, AdaBoost and Random Forest (RF) demonstrate superior predictive capabilities. Evaluation metrics such as Mean Absolute Error (MAE) and Mean Squared Error (MSE) confirm the high accuracy and reliability of the proposed approach, achieving R-squared ( $\mathrm{R}^{2}$ ) values above 0.98. By combining advanced technological tools with analytical methodologies, this approach has the potential to enhance fire suppression and management, safeguarding lives and assets.

Convolutional Neural Networks (CNNs) have received substantial attention as a highly effective tool for analyzing medical images, notably in interpreting endoscopic images, due to their capacity to provide results equivalent to or exceeding those of medical specialists. This capability is particularly crucial in the realm of gastrointestinal disorders, where even experienced gastroenterologists find the automatic diagnosis of such conditions using endoscopic pictures to be a challenging endeavor. Currently, gastrointestinal findings in medical diagnosis are primarily determined by manual inspection by competent gastrointestinal endoscopists. This evaluation procedure is labor-intensive, time-consuming, and frequently results in high variability between laboratories. To address these challenges, we introduced a specialized CNN-based architecture called GastroFuse-Net, designed to recognize human gastrointestinal diseases from endoscopic images. GastroFuse-Net was developed by combining features extracted from two different CNN models with different numbers of layers, integrating shallow and deep representations to capture diverse aspects of the abnormalities. The Kvasir dataset was used to thoroughly test the proposed deep learning model. This dataset contained images that were classified according to structures (cecum, z-line, pylorus), diseases (ulcerative colitis, esophagitis, polyps), or surgical operations (dyed resection margins, dyed lifted polyps). The proposed model was evaluated using various measures, including specificity, recall, precision, F1-score, Mathew’s Correlation Coefficient (MCC), and accuracy. The proposed model GastroFuse-Net exhibited exceptional performance, achieving a precision of 0.985, recall of 0.985, specificity of 0.984, F1-score of 0.997, MCC of 0.982, and an accuracy of 98.5%. ©2024 the Author(s), licensee AIMS Press.

Traditional control methods may struggle to adapt to the nonlinear and uncertain characteristics in Autonomous Vehicle Control. In recent years, fuzzy control techniques, such as the Takagi–Sugeno fuzzy controller, have emerged as promising approaches for handling such complexities. Fuzzy controllers utilize linguistic variables and fuzzy logic to model system behavior, offering flexibility and robustness in dealing with uncertainties. Furthermore, Lyapunov function analysis provides a powerful tool for assessing the stability of dynamical systems. By employing Lyapunov functions, researchers can mathematically prove the stability of a system and derive stability criteria, contributing to a deeper understanding of system behavior. This paper investigates the enhancement of stability in control systems by employing Fuzzy Gain Scheduling combined with Lyapunov function analysis. Stability is a crucial aspect of control systems, ensuring their reliable and efficient operation in various dynamic environments. Traditional control techniques often struggle to handle the nonlinear and uncertain nature of modern systems. FGS offers a flexible and adaptive approach to control by adjusting controller gains based on system operating conditions. Additionally, Lyapunov function analysis provides a rigorous mathematical framework for stability assessment, enabling the verification of system stability properties. By integrating FGS and Lyapunov function analysis, this research aims to develop a robust control strategy capable of ensuring stability across a range of operating conditions. Simulation and experimental results are presented to demonstrate the effectiveness of the proposed approach in enhancing stability and performance in control systems. Specifically, the settling time was reduced by 20%, and overshoot was minimized to 5% of the steady-state value. Furthermore, in experimental tests conducted on a real-world control system setup, the proposed approach demonstrated rob
