The number of people connected to internet has increased exponentially. This growth has spawned an unparalleled amount of information, both real and fake, that gets circulated through the digital networks with relative ease and permanence. The fast spread of fake news has created a desperate need of reliable and automated systems of detection. Ensemble learning has demonstrated some significant potential in alleviating this problem by boosting the strengths of classification by integrating diverse models. This study compares three ensemble learning methods - Bagging, Boosting, and Cascading to determine their relative effectiveness in classification tasks. The Bagging model, achieved an accuracy of 86.58% and a Matthews Correlation Coefficient (MCC) of 0.7392, showing high precision but low recall. AdaBoost with 50 estimators performed well with an accuracy of 83.74% and an MCC of 0.6752 in the Boosting category but Gradient Boosting outperformed it with an accuracy of 85.95% and a MCC of 0.7200. The cascading ensemble, combining multiple base classifiers, outperformed all other models with 90.06% accuracy, F1-score of 89.76% and Matthews correlation coefficient (MCC) of 0.8026. Findings reveal that cascading ensemble increases the model's resilience through the combination of complementary decision boundaries of different classifiers. Among the strategies that were evaluated, the cascading method with a multi model approach offers the best precision-recall balance, making it the most effective ensemble technique for the examined dataset.

Crop classification is important in improving agricultural production, efficiency in resource management and sustainable agriculture. The paper introduces a machine learning-based scheme of intelligent crop classification using agro-climatic and soil-related variables that are highly interconnected with the definite crop growth needs. The dataset includes the most important attributes, including the nutrient content (N, P, K), temperature, humidity, soil pH, and rainfall, all of which affect the suitability of crops and the potential to produce. Numerical methods of operation have contributed immensely to the efficiency of crop recommender systems in the sense that they have been able to capture the complexity of interactions between environmental factors and crop reactions. Four machine learning algorithms, i.e., Random Forest Classifier, Gradient Boosting Classifier, K-Nearest Neighbors, and Support Vector machine, were adopted and tested using typical performance indicators of accuracy, precision, recall and F1-score. In the experiment, the highest accuracy of 0.948 was obtained with the help of Random Forest and Gradient Boosting classifiers, which proves that they are more effective in approximating non-linear patterns and minimizing classification error. K-Nearest Neighbors and Support Vector machine yielded good results also having a 0.943 and 0.936 accuracy respectively and this confirms their applicability in the differentiation of crops using multi-dimensional feature space.
Parkinson's disease (PD)—being a gradual neurodegenerative disorder affecting motor and cognitive skills—requires early and proper diagnose for effective management. This work applies advanced ensemble machine learning methods, stacking, and cascading algorithms for a better diagnosis of Parkinson's disease. The study uses a diverse dataset consisting of patients' demographic data, clinical features, and diagnostic features, trying to prove that ensemble methods outperform individual machine learning algorithms. The results show that ensemble learning methods much better predict and resist uncertainty, proving better than the base classifiers with 95.01% accuracy, 96.93% recall rate, and 0.8938 in Matthews Correlation Coefficient (MCC). That is to say, the other methods do offer improvements la stacking, which forms a meta-classifier out of multiple models, and cascading, which processes predictions from one model into the next, gives great improvements over stand-alone methods with very strong diagnostic precision. Such findings suggest that ensemble learning effectively minimizes false classification rates and thereby improves the early detection of Parkinson’s disease. The study emphasizes machine learning, especially ensemble methods, as the operating system within decision support for clinical systems for neurodegenerative disorders. With the diversity in patient data and model integration optimization, they certainly pave the road to enhanced diagnostic accuracy. Subsequent investigations may consider the use of larger multicenter data sets, more biomarkers, and deployments in real-time healthcare settings to further assess and improve predictive models.

Most of the developing countries rely on agriculture for their annual growth, a greater section of GDP contribution is affected by its agriculture. Alongside this, major industries rely upon the agricultural to derive their profit. The farmers of many countries are still dependent on classical methods as they are not aware of various technologies and lack significant knowledge in the sector. Consequently, the loss in the agricultural domain accounts for poor quality seed and delayed sowing, environmental hazards, attacks by insects, irrelevant harvesting etc. However, these factors cannot be controlled but can be monitored and an effective strategy can be adopted with the help of the Internet of Things (IoT). IoT-assisted agriculture can help to monitor the conditions and predict the yield which can be useful in taking decision about crops. However, there are no concurrent real-time forecasting strategies that can avail the inputs from different sensors and give parameter-specific or complete forecasting of the yields. To overcome this issue, a Rule-Based Context-Aware (RBCA) framework is proposed that considers a specialized IoT setup to help yield-forecasting of different crops by using available parameters as input. The proposed model uses a probabilistic mapping theory with residual analysis. The model can help to analyze if the given conditions of agriculture-setup are good enough for the growth of a particular crop by using the standard growing environment as matching criteria. Both numerical and realtest data for various crops between the years 1981 and 2012 are used for evaluating the performance of the model.

Accurate fracture classification is essential for efficient diagnosis and treatment planning. This paper presents a CNN-based automated fracture classification model and verifies its high accuracy and reliability. The model was verified with a confusion matrix heatmap, which verified its exceptional performance with negligible misclassifications. Fracture Dislocation, Comminuted Fracture, and Pathological Fracture were correctly identified with 100% accuracy, and misclassification errors were insignificant. The model achieved an overall accuracy of 99%, and precision, recall, and F1-scores were always between the range of 0.97 and 1.00. High macro-average and weighted average scores also validate its generalizability. The CNN architecture, consisting of convolutional, pooling, and fully connected layers, efficiently extracts and processes useful features in a computationally efficient way. Training analysis indicated a high convergence trend, with accuracy progressively improved and loss substantially decreased with each epoch. The steep decline of loss in initial stages of training verifies an optimized learning process, which testifies to the reliability of the model. This paper suggests that the proposed CNN model offers a strong and efficient solution for automated fracture detection. Future work will involve dataset expansion, including heterogeneous imaging modalities, and model optimization for clinical deployment.
Parkinson's disease (PD) is a chronic, non-fatal, and well-known progressive neurological disorder, the symptoms of which often overlap with other diseases. Effective treatment of diseases also requires accurate and early diagnosis, a way that patients can lead healthy and productive lives. The main PD signs are resting tremors, muscular rigidity, akinesia, postural instability, and non-motor signs. Clinician-filled dynamics have traditionally been an essential approach to monitoring and evaluating Parkinson's Disease (PD) using checklists. Accurate and timely diagnosis of Parkinson's disease (PD), a chronic and progressive neurological ailment, can be difficult due to its symptoms overlapping with those of other disorders.

Transfer learning improves generalization and permits domain adaptation, especially for small or resource-constrained datasets, while lowering training time, resource needs, and overfitting concerns. This work aims to design and assess a general transfer learning paradigm for the reliable prognosis of Parkinson’s disease based on DaTscan images that consider feature extraction and the performance of a variety of ML algorithms. This work aims to explore the use of transfer learning with pre-trained deep learning models to extract features from DaTscan images in order to improve classification accuracy. The sample of this study is made up of 594 DaTscan images from 68 participants, 43 with PD and 26 healthy. Out of the four algorithms employed; the Random Forest, Neural Network, Logistic Regression, and Gradient Boosting models, transfer learning-based features were applied. Four indices of accuracy, namely Area Under the Curve (AUC), Classification Accuracy (CA), F1 Score, Precision, Recall and Matthews Correlation Coefficient (MCC) were used to evaluate four machine learning models on a PD classification task such as Random Forest, Neural Network, Logistic Regression, and Gradient Boosting. Neural networks outperformed the other models, showing robustness and reliability with an AUC of 0.996, CA of 0.973, and MCC of 0.946. Gradient Boosting performed competitively, coming in second with an AUC of 0.995 and MCC of 0.925. Random Forest performed the worst, with an AUC of 0.986 and an MCC of 0.905, whereas Logistic Regression had an AUC of 0.991 and an MCC of 0.926.

The paper is a comparative analysis of two popular deep learning architectures, EfficientNet and ResNet-50, which are used as feature extractors with four additional classifiers: Neural Network, Logistic Regression, Gradient Boosting, and Random Forest. Experimentation was done on a dataset of 4,217 fundus images (4 eye conditions, Normal, Cataract, Glaucoma, and Diabetic Retinopathy). The deep features were extracted and they were used to train the classifiers and their performance measured by using accuracy, F1-score, AUC and MCC. It is observed that EfficientNet with a Neural Network gives the best results with an AUC of 0.980 and a precision of 0.888. Logistic Regression and Gradient Boosting also score well with the Random Forest always scoring the lowest points.
