A machine learning technique to diagnose thyroid disease via proper analysis is a major classification problem. the thyroid organ is an important part of our body. It helps to control our metabolism. Less amount of thyroid hormone causes hypothyroidism, and more amount of thyroid hormone causes hyperthyroidism. therefore, the current work objective was to build a machine learning-based classification model to classify samples withthyroid disease from a publically available dataset. the classes were labeled as healthy and thyroid disease with many explanatory variables. A class balancer, namely Synthetic Minority Oversampling Technique (SMOTE), was used to balance the minority class (thyroid disease) in the dataset. In this work, filter-based feature selection algorithms, specifically mutual information in conjunction with a two-class Neural Network (NN) classifier, was used with Azure Machine learning tools to construct a predictive model. Our proposed two-class NN model build using selected features in association with SMOTE performed better than other recent ML models with an F1Score (0.982), precision (0.968), recall (0.995), and accuracy (0.981), respectively.
Linear discriminant analysis (LDA) is one of the most classical linear projection techniques for feature extraction, widely used in kinds of fields. Classical LDA is contributed to finding an optimal projection subspa...

To meet the demands of users in green building and to reduce the learning cost by intelligent control system, this paper establishes the overall design framework of intelligent control system for green building, and formulates the specific implementation scheme of system hardware and software, as well as the overall control strategy of the system. We use Kingview and Zigbee ad hoc network technology to establish wireless sensor network, to transmit and store all kinds of sensor data. RS485 bus is adopted to realize switch control of household equipment and irrigation solenoid valve, and Modbus-RTU protocol is used to realize system monitoring and control. then, the temperature control subsystem based on fuzzy-PID control algorithm is established according to the relevant theory of the fuzzy-PID control algorithm, and the simulation experiment is completed in MATLAB, which achieves better control effect. Finally, through the functional test of the acquisition and the control part of the system, it is proved that the scheme achieves the expected design requirements.

At present, in the field of fault diagnosis, deep learning has shown state-of-the-art performance in processing mechanical big data. this paper studies the deep neural networks(DNN) model based on auto-encoder, which has high performance in bearing fault diagnosis. However, the traditional structure of stacked auto-encoders has the problem of internal covariant transfer, that inhibits the training efficiency and generalization ability of the network. To overcome the aforementioned deficiency and further explore the performance of DNN, a batch normalization layer is employed in the fully connected layer of the DNN during training, so the network can obtain the stable distribution of activation values. therefore, this paper proposes a new intelligent diagnosis method named batch normalization deep neural networks(BN-DNN). Finally, the experimental results show that: (1) the performance of BN-DNN is better than DNN. (2) BN-DNN can directly process the raw vibration signals, and the diagnostic accuracy can be maintained above 99% under different working conditions.

the new load balancing methods plan to disseminate the load to the proxy servers ideally and amplify usage of the network, avoiding traffic and delay along the way. In this paper, we are proposing a novel approach for optimizing the router request time to minimize the delay, which exploits the adaptability and programmability of Software-Defined Networking. It is done by creating CDNs and balancing load using surrogate networks. It will lower the load on the original server. the load balancing is done using shortest path selection through the utilization of neural networks as a machine learning technique to choose the node withthe highest energy level and determine the fastest route for data transfer. this enhancement work in this paper is done for specific types of networks like wireless networks during the session layer transmission. In the selection process of the node for data transfer, we could use a neural network instead of a decision tree. the paper concludes withthe evaluation of achieved results and the comparison against the of performance metrics of other pre-existing approaches.

In recent years, software maintainability has become a critical attribute in software engineering to determine software quality. Hence, predicting this maintainability in an accurate and timely manner is a fundamental requirement for effective management during the software maintenance phase. this has led the software developers to pay more attention to those modules that need high maintenance. the current study proposes an Optimized Extreme learning Machine (OELM) algorithm for Software Maintainability Prediction (SMP) using three open-source datasets, viz.: Abdera, Ivy, & Rave. Since all these datasets are initially imbalanced, a Random Over Sampling technique is also used for re-sampling to avoid any problem encountered due to the imbalanced distribution of datasets. the predictive performance is analyzed based on the three performance evaluation measures, i.e., Accuracy, F1-Score, & Area under the ROC Curve. the results support the effective utilization of the proposed OELM algorithm in SMP. the OELM algorithm's performance is also compared with four different Machine learning (ML) algorithms, namely AdaBoost, Bagged CART, Flexible Discriminant Analysis, and Penalized Multinomial Regression. this comparison further supports the effectiveness of the OELM algorithm in predicting maintainability. the OELM algorithm performs 7.82%, 8.54%, and 22.98% better for Abdera, Ivy, and Rave datasets, respectively, than the other four ML algorithms taken together concerning Accuracy.

the protection of citizens' public financial resources through advanced corruption detection models in public procurement has become an almost inevitable topic and the subject of numerous studies. Since it almost always focuses on the prediction of corrupt competition, the calculation of various indices and indications of corruption to the data itself are very difficult to come by. these data sets usually have very few observations, especially accurately labelled ones. the prevention or detection of compromised public procurement processes is definitely a crucial step, related to the initial phase of public procurement, i.e., the phase of publication of the notice. the aim of this paper is to compare prediction models using text-mining techniques and machine-learning methods to detect suspicious tenders, and to develop a model to detect suspicious one-bid tenders. Consequently, we have analyzed tender documentation for particular tenders, extracted the content of interest about the levels of all bids and grouped it by procurement lots using machine-learning methods. A model that includes the aforementioned components uses the most common text classification algorithms for the purpose of prediction: naive Bayes, logistic regression and support vector machines. the results of the research showed that knowledge in the tender documentation can be used for detection suspicious tenders.
