Due to high cost and time spent on traditional negotiation, in the last two decades automated negotiation has been considered. Similarly, in an automated negotiation, competing parties often do not reveal their complete or true preferences. Such setting is called an incomplete information environment. To overcome the complexity that it generates, agents can try to use online opponent modeling, learning the preferences of the opponent during the negotiation. This paper tries to find settings in which the opponent modeling helps agents to improve their performance in a bilateral negotiation. The results of the experiments show that the use of modeling by one or both of the agents will definitely improve social welfare. But when one agent uses opponent modeling, its utility is not necessarily increased.","PeriodicalId":386952,"journal":{"name":"2017 Artificial Intelligence and Signal Processing Conference (AISP)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133843051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this framework, clustering can be done based on the structure of a base classifier. By use of this framework, new clustering methods can be generated, or some classic ones may be regenerated considering underlying theory of a particular classifier. As a sample of the proposed framework, Parzen windows classifier is used as the base classifier to generate a variety of clustering algorithms including some well-known methods, complete and single linkage.","PeriodicalId":386952,"journal":{"name":"2017 Artificial Intelligence and Signal Processing Conference (AISP)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114463075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Search-based methods extract relevant tags for an image based on the tags of nearest neighbor images in the training set. In these methods, similarity of two images is determined based on the distance between feature vectors of the images. Thus, it is essential to extract informative feature vectors from images. In this paper, we propose a framework that utilize deep learning to obtain visual representation of images. We apply different architectures of convolutional neural networks (CNN) to the input image and obtain a single feature vector that is a rich representation for visual content of the image. In this way, we eliminate the usage of multiple feature vectors used in the state-of-the-art annotation methods. We also integrate our feature extractors with a nearest neighbors approach to obtain relevant tags of an image. Our experiments on the standard datasets of image annotation (including Corel5k, ESP Game, IAPR) demonstrate that our approach reaches higher precision, recall and F1 than the state-of-the-art methods such as 2PKNN, TagProp, NMF-KNN and etc.","PeriodicalId":386952,"journal":{"name":"2017 Artificial Intelligence and Signal Processing Conference (AISP)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122203868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Advantages of device-to-device communications include increased spectral efficiency, increased power and energy efficiency, increased capacity, service quality assurance, reduced interference, improved reliability, reduced latency, improved coverage and cost efficiency. However, the using of device-to-device communication technology in the cellular networks causes interference; because the same resources are shared between two types of users. Hence, we need to reduce the interference between the devices-to-device in the cellular network. One way to prevent interference or reduce it is to allocate resources appropriately.

These kinds of data have some limitations which make them different from batch datasets and therefore the process of learning is confronted with many challenges. Since concept drift is one of the most important challenge among them, different techniques as well as our proposed method focus on solving this issue. Our method sequentially updates the constructed model such that the structure and parameters always remains compatible with any new characteristics of data. For having low computational time of modifying the model, we propose a simple updating formula based on minimizing the classification accuracy in each step through gradient descent.

Signal classification is based on optimized Support Vector Machine (SVM) by Particle Swarm Optimization (PSO) algorithm. EEG signals of FC3, C3, CP3, FC4, C4 and CP4 Channels that are related to hands movement as well as Cz and FCz channels that are related to feet movement are considered. Radial basis function (RBF) and penalty functions of SVM are optimized through PSO algorithm. For validation of SVM-PSO classifier, the EEG signals are collected from two databases: PhysioNet and BCI Competition III, then features including Power Spectral Density (PSD) and wavelet parameters are used as the input of the classifier. By comparing the results of the SVM and SVM-PSO classifiers, is concluded that performance of classifier in terms of accuracy is increased through PSO algorithm. SVM-PSO classification accuracy for wavelet and PSD features are obtained 81% and 92%, respectively. The best algorithm is used to control a two degrees of freedom (one for left and right hand movements and the other for left and right foot movements) industrial robot experimentally.

We perform a wide range of our daily tasks with mobile devices like browsing the internet, checking mail, social networking and transforming money. As these smart devices become more popular and usable, they attracted more attackers. Recently, mobile malwares increased sharply and their caused detriments menace the usability and privacy due to the sensitive data which are stored in these devices. According to the intense increase in the number of these attacks yearly, malware detection becomes a prominent topic in mobile security. Since traditional signature based techniques which are used by commercial anti-virus have failed to detect new and obfuscated malwares, machine learning approaches have been employed to find and detect behavior patterns of malwares from extracted features. In this paper, a new heuristic malware detection technique was proposed based on compression methods. The momentous superiority of this approach is using opcode as an input for compression models which causes accuracy to be increased. To assess the potency of the proposed methods, several experiments are conducted. The experimental results of method show promising improvement of accuracy to support the main idea.","PeriodicalId":386952,"journal":{"name":"2017 Artificial Intelligence and Signal Processing Conference (AISP)","volume":"2022 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127606585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, we propose an elegant way to create initial rule-base according to the solution of the underlying MDP to increase the performance of the algorithm. We evaluate our proposed approach on several standard benchmark problems and compare it to the state-of-the-art methods.
