This problem can reduce the accuracy of classification models and affect the validity of results. The aim of our paper is to compare several techniques for correcting class imbalances in medical datasets and to evaluate the impact of these techniques on machine learning performance. In our paper, we used an imbalanced dataset to train a convolutional neural network (CNN) model. We then tested correction techniques such as sampling and cost-sensitive learning. Finally, we used recall, precision, accuracy and F1 score to evaluate the model's performance. The results show that the use of correction techniques led to a significant improvement in the performance of the classification model. The cost-sensitive learning technique gave the best results, particularly for the detection of minority classes. This method increased the weight of classification errors associated with minority classes, thus improving the detection of critical cases. The results of this study underline the importance of dealing with imbalances in the data to improve the performance of classification models in the medical field. The use of methods such as cost-sensitive learning not only improves model performance, but also enables more reliable decisions to be made, which is essential for ensuring more accurate diagnoses and better quality of care.

The high costs of traditional treatments and the limited availability of specialized medical equipment contribute to these challenges. Current diagnostic methods often rely on specific electrocardiogram (ECG) parameters, which may not capture the nuanced complexities necessary for accurate diagnosis. To address these issues, our study proposes an innovative solution: an accessible and cost-effective ECG monitoring system. This system not only captures electrical signals from the heart but also translates them into numerical values using advanced modulation techniques. A trained deep learning model then analyzes this data to accurately identify any potential complications or confirm a healthy cardiac state. Our approach also allows for remote diagnosis and treatment. By utilizing an MQTT server, ECG data can be efficiently transmitted to experts for evaluation and intervention when necessary. Our meticulously fine-tuned Artificial Neural Network (ANN) architecture has achieved an impressive accuracy of 95.64%, surpassing existing methodologies in this field. Designed with resource-strapped regions in mind, our system offers a lifeline to rural areas lacking access to medical professionals and advanced equipment. Its affordability ensures that even individuals with limited financial means can benefit from timely and accurate cardiac monitoring, potentially saving lives and reducing the burden of cardiovascular diseases in underprivileged communities.

These devices can handle small to medium computing tasks, but they fall short when it comes to large-scale processes, making computational offloading a crucial solution. Cloud computing and fog computing provide an effective platform for offloading tasks from mobile devices.

By intelligently adjusting user power levels, the proposed approach significantly improves detection reliability while maintaining stringent false alarm constraints, even under challenging low-SNR conditions. The goal is to enhance spectrum sensing performance by maximizing the probability of detection (Pd) while maintaining a constrained probability of false alarm (Pf). Cyclostationary Feature Detection (CFD) and Matched Filter Detection (MFD) techniques are applied to evaluate detection performance under varying Signal to noise ratio (SNR) conditions. Simulation results demonstrate that the optimized framework not only strengthens detection performance particularly for high order QAM but also enhances overall system responsiveness.  Also CFD surpasses MFD in higher SNR scenarios due to its ability to exploit cyclic features of modulated signals, which are preserved even in moderately noisy environments. The integration of PSO further enhances system performance, offering a practical and scalable solution for next-generation Internet of Things (IoT)-enabled spectrum sharing environments.
