This paper investigates the application of machine learning models for Non-Performing Loan (N. P. L) prediction in the banking sector. The study evaluates the accuracy of diverse models, including traditional algorithms and advanced machine learning approaches such as Random Forest, Gradient Boost, XGBoost, LSTM, Decision Tree, Gaussian Naive Bayes and LightGBM. Training of the models are done on the dataset 'Training Data,’ available on Kaggle under the notebook named “Loan Prediction Based on Customer Behaviour”. Data processing and analysis of the given dataset was done on Kaggle's Jupyter Notebook cloud environment by using Python programming libraries. Through rigorous experimentation, it has been attested that Random Forest classifiers stands out to be best performing model when tested across all the performance benchmarks. This information thereby offers valuable guidance for institutions aiming to strengthen N. P. L prediction mechanisms and overall risk management strategies.

Nowadays, optimizing the results of machine learning algorithms is of great importance in the field of artificial intelligence. This article analyzes the effectiveness of Lasso, Ridge, and Elastic Net regression methods to increase the reliability of the results of machine learning algorithms in assessing economic indicators. These methods help to eliminate the problems of overfitting and multicollinearity, and are aimed at improving models based on machine learning algorithms. The study tests the effectiveness of these methods on a data set of economic indicators, and uses the Grid Search method to determine the optimal values for model parameters. As a result, it is shown that these approaches can improve the accuracy and generalizability of economic indicator assessments.

Diabetes is one of the most chronic conditions seen worldwide. Its prevalence has been causing many complications, such as cardiovascular diseases, kidney failure, and neuropathy. Early prediction is crucial in helping prevent these from occurring or, at worst, to be affected minimally. In this work, we implemented various machine learning techniques to predict the onset of diabetes based on demographic and health-related data like age, body mass index (BMI), hypertension, heart disease, and blood glucose levels. The used algorithms were XGBoost, Random Forest, Stacked Ensemble, Gradient Boosting machine (GBM), and Support Vector machine (SVM). XGBoost could reach a maximum AUC of 0.979653 and a log loss of 0.0789284 with an F1-score of 0.811485. These really demonstrated strong power in the prediction of diabetes. High performance was also highlighted with the Stacked Ensemble Model, reaching an AUe of 0.979579 and an accuracy of 97.22%. These outcomes suggest that the superior ensemble methods, XGBoost and Stacked Ensembles, will provide quality prediction such that earlier diagnosis of patients with diabetes might be achieved consequently and, therefore, good recovery.

This paper examines the impact of feature selection on phishing website detection using machine learning techniques. We utilize the UCI Phishing Website dataset, which consists of 11,055 instances and 30 features with no missing values. Our results show that the random forest outperforms logistic regression, achieving an accuracy of 97.11%. By analyzing feature importance, we optimize the model by removing detrimental features, further improving accuracy to 97.74%. This study highlights the effectiveness of the random forest in phishing detection and underscores the importance of feature selection in enhancing model performance.

This study aimed to predict Coronary Heart Disease (CHD) mortality over a 10 to 15-year period using machine learning (ML) techniques. We studied a rather large variety of features associated to CHD mortality from the Sleep Heart Health Study (SHHS) dataset. Using the most important features identified through mutual information, several ML algorithms, including LR, SVM, KNN, ETC, and RF, were trained. A 10-fold cross-validation was employed to ensure accuracy. As a result, the KNN algorithm (k = 18) outperformed the others, achieving an accuracy of 76.05%, an AUC of 79.41%, a sensitivity of 81.08%, a specificity of 71.28%, and a precision of 73.48%. Our proposed approach reasonably well predicts CHD mortality many years in advance, aiming to identify critical factors for CHD mortality prediction, monitor patients, and provide early warnings of the need for prevention and treatment through medical intervention.

Stock price prediction is a challenging and dynamic task due to the high volatility and complexity of financial markets. In this study, we present a comparative analysis of several machine learning algorithms applied to the prediction of stock prices. The models explored include Gradient Boosting Regressor (GBR), Gated Recurrent Unit (GRU), Linear Regression (LR), Long Short-Term Memory (LSTM), Random Forest (RF), and Support Vector Regression (SVR). Using a dataset comprising historical stock prices from multiple companies, we evaluate the performance of each model based on accuracy and predictive stability. Daily predictions were generated for each model, and the results were assessed using metrics such as average deviation from real price. The analysis indicates that while deep learning models like GRU and LSTM exhibit a strong capacity to capture temporal patterns, ensemble methods such as GBR and RF also provide competitive accuracy for short-term forecasts. This research highlights the strengths and limitations of various approaches to stock price forecasting and offers insights into their potential applications for investment decision-making. Future work may involve extending this analysis to broader financial datasets and investigating the integration of additional market factors.

This study aims to predict the tendency of homeowners in Turkey to purchase Compulsory Earthquake Insurance (CEI) using nine different machine learning (ML) classification algorithms. The dataset includes 11 independent variables related to demographic, structural, and geographic attributes, and one binary dependent variable. Data were collected via an online survey and preprocessed by removing incomplete responses. The Gradient Boosting (GB) algorithm achieved the highest performance with 70% accuracy. According to the SHAP (SHapley Additive exPlanations) analysis, "Monthly Income," "Square Meter Area," "Number of Floors," and "Construction Year" were the most significant features. The Odds Ratios (ORs) demonstrate that individuals with higher income and those living in newer and larger residences exhibit a significantly greater likelihood of possessing CEI. It was observed that individuals with higher education levels were less inclined to purchase insurance. Detailed analysis of the obtained results is expected to contribute to more effective policy-making in the insurance sector and among public authorities.

We present a comparative analysis of different machine learning algorithms for classifying electromyography (EMG) signals for the application of prosthetic arm development. We applied four machine learning algorithms, namely Support Vector machines (SVM), K-Nearest Neighbors (KNN), Decision Trees, and Logistic Regression. These algorithms classified the signals into three classes mentioned. Our results show that SVM achieved the highest accuracy at 83 %, followed by KNN (77 %), Logistic Regression (75 %), and Decision Tree (74 %). These findings suggest that SVM is the most promising approach for EMG signal multiclass classification for the mentioned application. While these results provide a solid foundation, we discuss potential improvements through hyperparameter tuning and study with real EMG sensor data for prosthetics movement. This study contributes to the development of more responsive and intuitive machine learning-powered prosthetic arms, potentially enhancing the quality of life for individuals with upper limb amputations.

Predictive analytics is a crucial tool in business decision-making, enabling companies to forecast trends, optimize strategies, and enhance profitability. This study provides a comprehensive performance analysis of three machine learning algorithms-Random Forest (RF), Artificial Neural Networks (ANN), and Gradient Boosting (GB)-for business insights prediction. A structured dataset undergoes preprocessing, including feature engineering and encoding, before model training. Each algorithm is evaluated based on accuracy, precision, recall, Fl-score, and computational efficiency. Results indicate that Gradient Boosting outperforms the others in accuracy (90.2 %), while ANN offers superior generalization. Random Forest provides a balance between interpretability and performance. This comparative analysis aids businesses in selecting appropriate models based on their computational constraints and prediction goals.
