Traffic congestion caused by greater competition for limited parking spaces in the world's major cities is a growing problem. To overcome this challenge, a study has been carried out to use a smart parking application that utilises machine learning algorithms to help predict future car parking occupancy rates at Port Macquarie campus of Charles Sturt University (CSU), Australia. Parking data was collected over a five-week period and the WEKA Machine learning Workbench was used to identify high-performing algorithms for predicting future parking occupancy rates. In the initial phase, some well known algorithms were used to investigate occupancy rates. In the next phase of the study, student class timetable data was used to enhance prediction accuracy and investigate parking occupancy trends. While most algorithms proved to be accurate in stable conditions, the KStar algorithm appeared to produce better results during highly variable conditions.

Heart disease is one of the most common problems and also a disease whose rate of increase has been higher in recent years. the complex task associated is exploitation of hidden patterns for effective and accurate prediction. there is plenty of data generated every year from various health institutes. this research focuses on development of supervised machine learning models for prediction of target heart disease. We have used publicly available heart disease datasets from University of California, Irvine (UCI) data repository for Cleveland, Switzerland, Hungarian and Long Beach. Various forms of preprocessing steps such as handling the missing values and null values, removal of duplicate entries is employed on these datasets in order to use it for developing effective models. the correlation between the features set and the target variable is studied. the prediction models are developed using effective machine learning techniques like Logistic Regression, Decision Trees, Naive Bayes, K-nearest neighbors, ensembles AdaBoost and XGBoost. the predictive performance of the developed models is compared withthe help of stable accuracy measures like accuracy, precision, recall, F1-seore, Cohen's kappa and Area Under the Curve score. K- nearest neighbors was the best model for the Cleveland dataset with 86.81% accuracy. AdaBoost algorithm gave us the highest accuracy of 98% for Switzerland dataset. Bernoulli Naive Bayes predicted the heart diseases for Hungarian dataset with 84.26% accuracy. XGBoost gave better accuracy of 82.20% for VA Long Beach dataset. the results of the study advocate the applicability of machine learning techniques to predict heart disease.

Software-Defined Networking (SDN) simplifies hardware-centric network architecture by employing forwarding devices (switches), SDN controller, and SDN applications. Depending on the SDN application that manages the controller, controller can turn a switch to act as a switch, router, firewall, etc. SDN also enables switch to access more network information through controller. Our proposed SDN application consists of traffic monitoring module and routing module to optimize the network. Traffic monitoring module will monitor switches' port utilization and routing module uses deep reinforcement learning agent trained with deep deterministic policy gradient to manage switch forwarding. Relevant flow entries are issued to OpenFlow switches to manage switch forwarding. Agent changes the routing according to the switches' port utilization and learn the best routing to minimize packet loss. the proposed method will be implemented and evaluated in the future work using Mininet to emulate data layer (hosts, switches) and open source SDN controller Ryu.

In many industries, the development is aimed towards Industry 4.0, which is accompanied by a movement from large to small quantities of individually adapted products in a multitude of variants. In this scenario, it is essential to be able to provide the price for these small batches fast and without additional costs to the customer. this is a big challenge in technical applications in which this price calculation is in general performed by local experts. From the age of expert systems, one knows how hard it is to achieve a formalised model-based on expert knowledge. So it makes sense to use today's machine learning techniques. Unfortunately, the small batches combined with typically small and midsize production enterprises (SMEs) lead to smaller databases to rely on. this comes along withdata which is often based on 3D data or other sources that lead in the first step to a lot of features. In this paper, we present an approach for such use cases that combines the advantages of model-based approaches with modern machine learning techniques, as well as a discussion on feature generation from CAD data and reduction to a low-dimensional representation of the customer requests.

With an. upsurge in the rate of data production., pervasive usage of cameras for automation and surveillance and the requirement of visual input for artificially intelligent devices all across the globe, there has been a rapid increase in the mass of image data being generated today. this gives rise to the essentiality of automated image processing required to simplify image related tasks. automated image processing bridges the gap between the human visual system and the pixel level data of images. Deep Convolution Neural Networks are being deployed expansively to analyze detect and classify images for a diverse number of tasks. these neural networks, similar to the human neural network, contain neurons with learnable weights and biases, which are trained to identify and classify different objects or features across the image. this paper presents a functional implementation of image recognition using a small convolutional neural network, proposing less complexity and yielding good classification accuracy for all tested data sets.

Research into sentiment analysis and its capabilities at analysing product reviews has increased tremendously in recent years. In this paper, we propose an approach to classify product reviews and identify use cases. Several iterations showing the application of natural language processing techniques and machine learning classifications are depicted. A number of machine learning classifiers are trained/tested in various iterations, their performance and accuracy at predicting the existence of use cases in product reviews is evaluated.

this research aims to examine automatic models to classify thai online news articles. the data set is six thousands of news articles from three mainstream websites. the news articles are classified into four categories-crime news, politic news, sport news, and entertainment news. Examinations on the classification algorithms of Decision Tree, Support Vector Machine (SVM), and Deep learning are conducted. the performance is measured by the accuracy, the recall, the precision, and the F-Measure. the results show that the accuracies of Decision Tree, SVM, and Deep learning models are 86%, 94%, and 95%, respectively.
