To ensure a higher quality, capacity and production of rice, it is critical to diagnose disease early in order to decrease the usage of pesticides and reduce agricultural and environmental damage. Therefore, a Multi-scale YOLO v5 detection network is proposed to resolve rice crop disease in its early stage. The experiment initially starts with the rice leaf images from the RLD dataset for pre-processing, after which data set labels are created, which are then divided into train and test sets. DenseNet-201 is used for the backbone network and depth aware instance segmentation is used to segment the different regions of rice leaf. At next, the proposed Bidirectional Feature Attention Pyramid Network (Bi-FAPN) is used for extracting the features from the segmented image and enhances the detection of disease with different scales. The feature maps are finally identified in the detection head, where the anchor boxes are then applied to the output feature maps to produce the final output vectors by the YOLO v5 network. The experiments are conducted with RLD dataset with different existing networks. The effectiveness of the network is evaluated based on various parameters in terms of average precision, accuracy, average recall, IoU and F1 score.
Since Remote sensing images are used for a variety of applications, classification of such images is essential for extracting information. However, due to the lack of sufficient training examples, classification of remote sensing images is more complex. Also, in traditional method of classification, the statistical procedure uses only the gray value of the digital images to extract information. Neural network (NN) has a better impact in this domain. The proposed work uses an integrated NN and cuckoo Optimisation Algorithm (COA) for classification. The NN picks, organise and constructs the data to be trained into a network. The network is then trained and tested. The COA is combined with NN to aid the task of classification and to calculate the cost function. The optimization algorithm provides an appropriate feature suitable for the neural network classifier to produce final output. This hybridized technique presents the effective advantages of the neural network and further investigate the classification of the multispectral remote sensible images. The performance and error rate of the system is better when compared with other classical methods. The observed results illustrate the effectiveness of the COA to optimize the cost function. As training parameters in Neural network is found to be NP hard, utilization of COA involve its responsibility in optimizing the learning rate of NN.

Cardiovascular diseases are among the foremost common serious diseases’ poignant human health. Disorder is also prevented or relieved by early diagnosis, and this might scale back mortality rates. Distinctive risk factors mistreatment machine learning models may be a promising approach. The model that comes with totally different strategies to realize effective prediction of heart disease. For this planned model to be successful, economical information collection, information Pre-processing and information Transformation methods to form correct info for the coaching model. The model has a combined dataset. Appropriate options are hand-picked by using the Relief and LASSO techniques. New hybrid classifiers like Random Forest based Machine Learning are developed by group action the normal classifiers with fabric and boosting methods, that are employed in the coaching process. Some machine learning algorithms to calculate the accuracy, sensitivity, error rate, precision. The results are shown singly to supply comparisons. Supported the result analysis will conclude that our planned model created the very best accuracy whereas mistreatment RFBM and Relief feature choice method.
