Malware includes computer viruses, worms, trojan horses, rootkit, adware, ransomware and spyware. Due to the explosive growth in number and variety of malware, the demand of improving automatic malware detection has increased. Machine learning approaches are a natural choice to deal with this problem since they can automatically discover hidden patterns in large-scale datasets to distinguish malware from benign. In this paper, we propose different deep neural network architectures from simple to advanced ones. We then fuse hand-crafted and deep features, and combine all models together to make an overall effective ensemble framework for malware detection. The experiment results demonstrate the efficiency of our proposed method, which is capable to detect malware with accuracy of 96.24% on our large real-life dataset.","PeriodicalId":448008,"journal":{"name":"Proceedings of the 9th International Symposium on Information and Communication Technology","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132942422","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}

{"title":"Refined Cattle Detection Using Composite Background Subtraction and Brightness Intensity from Bird's Eye Images","authors":"Mami Aotani, Ryo Nishide, Yumi Takaki, C. Ohta, K. Oyama, T. Ohkawa","doi":"10.1145/3287921.3287945","DOIUrl":"https://doi.org/10.1145/3287921.3287945","url":null,"abstract":"Breeding cattle are known to be social animals that make groups as humans. Focusing on the sociality of the cattle, this paper aims to grasp and predict the conditions of breeding cattle by detecting the interactions between them. In order to detect such interactions, it is necessary to follow the behaviors of the breeding cattle to examine how they approach each other. In this study, the positions and movements of the breeding cattle are detected from bird's eye images. In the preceding study, breeding cattle were experimentally detected by the background subtraction method using multiple background images because of the poor distinctive features of breeding cattle. However, the method employed in that study used images that may not completely remove breeding cattle in a background image in order to cope with the changing brightness, which may cause errors in detection. Moreover, a huge amount of time may be consumed in selecting the optimal background image for the input image. Therefore, we propose a method in this paper by applying composite background images and reduction of search images using brightness to the method of the preceding study. The composite background image is an image obtained by overriding other images to the breeding cattle region, resultantly removing the cattle region. When creating the composite background, we consider that the image that does not contain cattle region can be used as a background image which may successfully improve the detection accuracy. When selecting an optimal background image, we also consider as that the processing time will be shortened by reducing the search images by brightness. In the experiment, the precision and the processing time are compared based on the cases with or without composite background image and by reduction of the search images by brightness. As a result, it was confirmed that the detection accuracy was improved by the proposed method and the processing time could be shortened.","PeriodicalId":448008,"journal":{"name":"Proceedings of the 9th International Symposium on Information and Communication Technology","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125779528","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}

MIM arises in many applications, such as artificial intelligence, game theory, computer networks, VLSI design and marriage problems.

Detecting and communicating these changes are still performed manually by responsible developers and administrators. Such a mechanism will not be adequate anymore in the future of large-scale IoT environments. Therefore, we present a comprehensive framework named DECOM for automatic detection and communication of service changes. Here, we assume that capabilities and interfaces of IoT devices are described and provided through REST services. To be able to detect syntactic as well as semantic changes, we transform an extended version of the interface description into a logic program and apply a sequence of analysis steps to detect changes. The feasibility and applicability of the framework are demonstrated in an IoT application scenario.","PeriodicalId":448008,"journal":{"name":"Proceedings of the 9th International Symposium on Information and Communication Technology","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128983435","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}

Quantitative trading applies a wide range of computational approaches such as statistics, physics, or machine learning to analyze, predict, and take advantage of big data in finance for investment. This work studies core components of a quantitative trading system. Machine learning offers a number of important advantages over traditional algorithmic trading. With machine learning, multiple trading strategies are implemented consistently and able to adapt to real-time market. To demonstrate how machine learning techniques can meet quantitative trading, linear regression and support vector regression models are used to predict stock movement. In addition, multiple optimization techniques are used to optimize the return and control risk in trading. One common characteristic for both prediction models is they effectively performed in short-term prediction with high accuracy and return. However, in short-term prediction, the linear regression model is outperform compared to the support vector regression model. The prediction accuracy is considerably improved by adding technical indicators to dataset rather than adjusted price and volume. Despite the gap between prediction modeling and actual trading, the proposed trading strategy achieved a higher return than the S&P 500 ETF-SPY.","PeriodicalId":448008,"journal":{"name":"Proceedings of the 9th International Symposium on Information and Communication Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130694096","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}

Recently, deep neural architectures have shown a dramatic boost in performance, but they are often too slow and burdensome for embedded and real-time applications such as video surveillance. In this paper, we describe a new object detection architecture that is faster than state-of-the-art detectors while improving the performance of small mobile models. Moreover, we apply this new architecture into the problem of vehicle detection, which is central to traffic surveillance systems. In more detail, our architecture uses an efficient backbone network in MobileNetV2, whose building blocks consist of depthwise convolutional layers. On top of this network, we build a feature pyramid using separable layers so that the model can detect objects at many scales. We train this network with smooth localization loss and weighted softmax loss in tandem with hard negative mining. Both training and test sets are built from recorded videos of Ho Chi Minh and Da Nang traffic or selected from DETRAC dataset. The experimental results show that our proposed solution can still achieve an mAP of 75% on the test set while using only around 3.4 million parameters and running at 100ms per image on a cheap machine.","PeriodicalId":448008,"journal":{"name":"Proceedings of the 9th International Symposium on Information and Communication Technology","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115051640","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}
