Game theory has found widespread use in various fields like Economics, Biology, Political science, etc. and forms an aegis for logical decision making in these areas. In computer science, due to advancing technologies, there has been a pressing need to use game theory in various problems due to the lack of scalability of traditional solutions. There has been ongoing research in various fields of computer science like security, machinelearning, cloud computing, etc. where game theoretic approaches are extensively used. In this paper, we present a review on game theoretical approaches to various fields in computer science such as privacy preservation, network security and intrusion detection and resource optimization In the end, this paper provides a comparative study of various game models used in different applications in a tabular format.

To make a practical anomaly detection system for rotating machinery in large infrastructures, such as wind turbines, providing an explanation along with the detection results is important so that faults can be easily verified by human experts. Therefore, a method for providing a visual explanation of the predictions of a convolutional neural network (CNN)based anomaly detection system is considered in this paper. More specifically, the CNN used takes the monitoring target machine's vibrational data as input and predicts whether the target's state is healthy or anomalous. A CNN visualization technique is applied this network to obtain an explanation of its predictions. In order to evaluate the obtained explanation, it is compared with an expert diagnosis made on the same data set. The results indicate that the frequency used by the experts to detect faults was also included in the network's explanation, indicating that the proposed visualization method can be used to provide useful information to help experts verify faults.

Deep learning models have recently achieved incredible performances in the Computer Vision field and are being deployed in an ever-growing range of real-life scenarios. Since they do not intrinsically provide insights of their inner decision processes, the field of eXplainable Artificial Intelligence emerged. Different XAI techniques have already been proposed, but the existing literature lacks methods to quantitatively compare different explanations, and in particular the semantic component is systematically overlooked. In this paper we introduce quantitative and ontology-based techniques and metrics in order to enrich and compare different explanations and XAI algorithms.

Integration of industrial consumers into the smart grid concept can be facilitated by optimizing load forecasting for industrial consumers. Minimizing forecast errors can improve the supplier-consumer relationship by reducing balancing costs and anticipate possible network faults. The present paper aims to research the efficiency of machinelearningapplied for industrial load. The dataset consists of hourly recorded values for electricity consumption generated by a meat processing facility. In the context of installing complex monitoring systems with high frequency recording intervals, huge amounts of data will be generated that require detalied analysis and real time processing, otherwise the investments in the smart grid are not justified, consequently disfavouring the development and digitization of electrical networks. Integration of the industrial consumer into the smart grid concept can be applied in great detail at large industrial consumers through robust forecasting. Forecasting the energy behaviour of a industrial consumer is a difficult task, high forecasting errors have been obtained due to the unpredictability of the consumer.

This paper addresses the intractability of order crossover in a partial backordering inventory problem. Here, the Artificial Neural Network (ANN), which is a machine leaning algorithm is used to solve a stochastic inventory problem. The results for examining order crossover with the back-propagation ANN shows notable reduction in inventory cost in comparison to linear regression method. A numerical study is taken to demonstrate the findings. This paper further draws insight on effectiveness of machinelearning in comparison to regression.

Based on conditional gradient, this paper present an accelerated distributed online conditional gradient algorithm denoted by ACCDOCG, which can effectively tackle the high time complexity problem of the distributed online optimization algorithm. The proposed ACCDOCG algorithm allows the network optimization objective function to be decomposed into the sum of the local objective function of each node or agent, and it utilizes the local linear optimization Oracle to replace the projection operation to improve convergence rate of the algorithm. We also theoretically analyze the convergence properties of the algorithm by introducing two types of regret bound. Finally, experimental results are implemented on various tasks, which clearly demonstrates that ACCDOCG works well in practice and compares favorably to existed optimization algorithms.

In this paper, we presented a method to acquire haptic data of texture and its corresponding roughness and hardness perceptions simultaneously. We carried a psychophysical experiment, in which subjects wearing a haptic ring with pressure and displacement sensors explore fabricated object combined with 5 springs and a texture board. We obtained a dataset labeled with perceived magnitude of roughness and harness, which provides valuable guidance to implementing haptic classifications using machinelearning algorithms and improving the realism of haptic devices.

A key step in performing quantum dynamics for a chemical system is the reduction of dimensionality to allow a numerical treatment. Here, we introduce a machinelearning approach for the (semi)automatic construction of reactive coordinates. After generating a meaningful data set from trajectory calculations, we train an autoencoder to find a low-dimensional set of non-linear coordinates for use in molecular quantum dynamics. We compare the wave packet dynamics of proton transfer reactions in both linear and non-linear coordinate spaces and find significant improvement for physical properties like reaction timescales.

Discriminative models that require full supervision are inefficacious in the medical imaging domain when large labeled datasets are unavailable. By contrast, generative modeling-i.e., learningdata generation and classification-facilitates semi-supervised training with limited labeled data. Moreover, generative modeling can be advantageous in accomplishing multiple objectives for better generalization. We propose a novel multi-task learning model for jointly learning a classifier and a segmentor, from chest X-ray images, through semi-supervised learning. In addition, we propose a new loss function that combines absolute KL divergence with Tversky loss (KLTV) to yield faster convergence and better segmentation performance. Based on our experimental results using a novel segmentation model, an Adversarial Pyramid Progressive Attention U-Net (APPAU-Net), we hypothesize that KLTV can be more effective for generalizing multi-tasking models while being competitive in segmentation-only tasks.
