We develop ensemble Convolutional Neural Networks (CNNs) to classify the transportation mode of trip data collected as part of a large-scale smartphone travel survey in Montreal, Canada. Our proposed ensemble library is composed of a series of CNN models with different hyper-parameter values and CNN architectures. In our final model, we combine the output of CNN models using "average voting", "majority voting" and "optimal weights" methods. Furthermore, we exploit the ensemble library by deploying a Random Forest model as a meta-learner. The ensemble method with random forest as meta-learner shows an accuracy of 91.8% which surpasses the other three ensemble combination methods, as well as other comparable models reported in the literature. The "majority voting" and "optimal weights" combination methods result in prediction accuracy rates around 89%, while "average voting" is able to achieve an accuracy of only 85%.

Partial discharge measuring is the mean tool of diagnosis in High voltage systems, equipment and solid dielectrics. Void or any defect in solid dielectrics will produce the partial discharge and may cause permanent failure after some time. According to type of defect, it will produce different patterns of partial discharge. In this paper we will study patterns of partial discharge in solid dielectric that voids are artificially have made in this materials according to experimental measuring in High voltage laboratory. The patterns will distinct with neural network and results of different type of neural network will be discussed.
