Applications with large-scale data are processed on a distributed system, such as Spark, as they are data- and computation-intensive. Predicting the performance of such applications is difficult, because they are influenced by various aspects of configurations from the distributed framework level to the application level. In this paper, we propose a completion time prediction model based on machine learning for the representative deep learning model convolutional neural network (CNN) by analyzing the effects of data, task, and resource characteristics on performance when executing the model in Spark cluster. To reduce the time utilized in collecting the data for training the model, we consider the causal relationship between the model features and the completion time based on Spark CNN’s distributed data-parallel model. The model features include the configurations of the Data Center OS Mesos environment, configurations of Apache Spark, and configurations of the CNN model. By applying the proposed model to famous CNN implementations, we achieved 99.98% prediction accuracy about estimating the job completion time. In addition to the downscale search area for the model features, we leverage extrapolation, which significantly reduces the model build time at most to 89% with even better prediction accuracy in comparison to the actual work.

Image deconvolution has been an important issue recently. It has two kinds of approaches: non-blind and blind. Non-blind deconvolution is a classic problem of image deblurring, which assumes that the PSF is known and does not change universally in space. Recently, Convolutional Neural Network (CNN) has been used for non-blind deconvolution. Though CNNs can deal with complex changes for unknown images, some CNN-based conventional methods can only handle small PSFs and does not consider the use of large PSFs in the real world. In this paper we propose a non-blind deconvolution framework based on a CNN that can remove large scale ringing in a deblurred image. Our method has three key points. The first is that our network architecture is able to preserve both large and small features in the image. The second is that the training dataset is created to preserve the details. The third is that we extend the images to minimize the effects of large ringing on the image borders. In our experiments, we used three kinds of large PSFs and were able to observe high-precision results from our method both quantitatively and qualitatively.
