Robust online motion planning with reachable sets

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2013.Cataloged from PDF version of thesis.Includes bibliographical references (p. 51-55).In this thesis we consider the problem of generating motion plans for a nonlinear dynamical system that are guaranteed to succeed despite uncertainty in the environment, parametric model uncertainty, disturbances, and/or errors in state estimation. Furthermore, we consider the case where these plans must be generated online, because constraints such as obstacles in the environment may not be known until they are perceived (with a noisy sensor) at runtime. Previous work on feedback motion planning for nonlinear systems was limited to offline planning due to the computational cost of safety verification. Here we augment the traditional trajectory library approach by designing locally stabilizing controllers for each nominal trajectory in the library and providing guarantees on the resulting closed loop systems. We leverage sums-of-squares programming to design these locally stabilizing controllers by explicitly attempting to minimize the size of the worst case reachable set of the closed-loop system subjected to bounded disturbances and uncertainty. The reachable sets associated with each trajectory in the library can be thought of as "funnels" that the system is guaranteed to remain within. The resulting funnel library is then used to sequentially compose motion plans at runtime while ensuring the safety of the robot. A major advantage of the work presented here is that by explicitly taking into account the effect of uncertainty, the robot can evaluate motion plans based on how vulnerable they are to disturbances. We demonstrate our method on a simulation of a plane flying through a two dimensional forest of polygonal trees with parametric uncertainty and disturbances in the form of a bounded "cross-wind". We further validate our approach by carefully evaluating the guarantees on invariance provided by funnels on two challenging underactuated systems (the "Acrobot" and a small-sized airplane).by Anirudha Majumdar.S.M

Website Phishing Technique Classification Detection with HSSJAYA Based MLP Training

Website phishing technique is the process of stealing personal information (ID number, social media account information, credit card information etc.) of target users through fake websites that are similar to reality by users who do not have good intentions. There are multiple methods in detecting website phishing technique and one of them is multilayer perceptron (MLP), a type of artificial neural networks. The MLP occurs with at least three layers, the input, at least one hidden layer and the output. Data on the network must be trained by passing over neurons. There are multiple techniques in training the network, one of which is training with metaheuristic algorithms. Metaheuristic algorithms that aim to develop more effective hybrid algorithms by combining the good and successful aspects of more than one algorithm are algorithms inspired by nature. In this study, MLP was trained with Hybrid Salp Swarm Jaya (HSSJAYA) and used to determine whether websites are suspicious, phishing or legal. In order to compare the success of MLP trained with hybrid algorithm, Salp Swarm Algorithm (SSA) and Jaya (JAYA) were compared with MLPs trained with Cuckoo Algorithm (CS), Genetic Algorithm (GA) and Firefly Algorithm (FFA). As a result of the experimental and statistical analysis, it was determined that the MLP trained with HSSJAYA was successful in detecting the website phishing technique according to the results of other algorithms

Investigation of Preschool Education Teachers, Preschool Children and Mothers' Opinions on Artificial Intelligence

Nowadays, artificial intelligence, which is used in different fields with the increase in the number of works and transactions carried out in digital environment, is also used in the field of education. The main purpose of this study is to examine the views about artificial intelligence of preschool children, their mothers and teachers. The research was planned with phenomenology research design, one of the qualitative research methods. The study group of the research was formed by selecting a total of 30 people in the convenience sampling method, including 5 preschool teachers teaching in public and private independent kindergartens, 1 student from each teacher's 5-year-old class and his/her mother. The data were collected through interviews and the interview questions were prepared by the researchers as open-ended questions. According to the results of the research, it was concluded that although the teachers defined artificial intelligence on the correct scientific basis, they did not have sufficient knowledge, did not use it in educational environments to increase the productivity of children and were worried. Considering the answers given by mothers and children to the questions about artificial intelligence, it can be interpreted that artificial intelligence is not defined correctly and there is a lack of knowledge, mothers have concerns that artificial intelligence may be harmful for their children, and children see artificial intelligence as a living being that they can talk to

Detecting Poisoning Attacks on Hierarchical Malware Classification Systems

Anti-virus software based on unsupervised hierarchical clustering (HC) of malware samples has been shown to be vulnerable to poisoning attacks. In this kind of attack, a malicious player degrades anti-virus performance by submitting to the database samples specifically designed to collapse the classification hierarchy utilized by the anti-virus (and constructed through HC) or otherwise deform it in a way that would render it useless. Though each poisoning attack needs to be tailored to the particular HC scheme deployed, existing research seems to indicate that no particular HC method by itself is immune. We present results on applying a new notion of entropy for combinatorial dendrograms to the problem of controlling the influx of samples into the data base and deflecting poisoning attacks. In a nutshell, effective and tractable measures of change in hierarchy complexity are derived from the above, enabling on-the-fly flagging and rejection of potentially damaging samples. The information-theoretic underpinnings of these measures ensure their indifference to which particular poisoning algorithm is being used by the attacker, rendering them particularly attractive in this setting

Modelado en 3D de una puerta de la ciudad de Rennes del siglo XV: Portes Mordelaises

[EN] The Portes Mordelaises, remnants of the medieval city walls of Rennes, France, has been the subject of several archaeological excavations until 2017. From these excavations, we created a three-dimensional (3D) model of the site reconstructed as it would have appeared during the 15th century, including the surrounding plus the interiors of its famed towers. Once our efforts and results were officially recognised as being of national interest by the French Ministry of Culture and Communication, Department of Heritage and the National Museum Service of France, we presented our virtual model reconstruction in an exhibition curated by the Museum of Bretagne, entitled "Rennes, les vies d'une ville" (Rennes, the Lives of a City). This approach to 3D reconstruction of the site served to further study Rennes’ origins, its construction, organisation, as well as its historic relationship to surrounding territories. The main objective of this work was to investigate, using of a significant and com[ES] Las Portes Mordelaises, restos de las murallas medievales de la ciudad de Rennes, Francia, han sido objeto de varias excavaciones arqueológicas hasta el año 2017.

Web tabanlı bir yazılım uygulamasını barındırmak için uzun bir zaman boyunca kullanılan yegâne araç, sunucu edinme veya kiralama yoluyla web uygulamalarını kullanıcıların hizmetine sunmaktı. Bulut teknolojisinin ortaya çıkışı ile bu yönteme önemli bir alternatif ortaya çıkmıştır. Bulut sayesinde başta yazılım uygulamalarını barındırma hizmetleri olmak üzere, dosya depolama, veri işleme, veri tabanı barındırma gibi birçok hizmet Google ve Amazon gibi büyük şirketlerin yanında irili ufaklı birçok başka şirket tarafından da sunulmaya başlanmıştır. Sunulan hizmetler bulut başlığı altında tek bir hizmetten birden fazla hizmete kadar değişmektedir. Bulut kavramı sunulan servislerin dışsallığına gönderme yapmakla beraber yeterli olanağa sahip şirketlerin kendi bünyelerinde de oluşturabilecekleri bir altyapıyı da ifade etmektedir. Türkçe yazında bulut teknolojilerine yönelik ilgi mevcut olmakla birlikte bu çalışmalar bulut çözümlerinin kavramsal boyutlarını ele almakta ancak işletmeler açısından pratik yararları değerlendirmemektedir. Bu çalışmada, bu boşluğu doldurmak amacıyla yönetim bilişim sistemleri perspektifinde bulut platformunun olumlu ve olumsuz özellikleriyle ilişkili yazını incelenmiş; daha sonra yazında geçen ve risk veya olumsuzluk olarak ele alınan konuların yeni girişimler için geçerli olmayabileceği ortaya konmuştur. Ayrıca işletmelerin özellikle yeni girişimlerin bulut platformunu kullanmalarının yaratacağı faydalar ve geleneksel alternatifleri ile mukayesesi ele alınmıştır.Up to emerging cloud technologies, the only way to host a web application was by purchasing or renting a server or using hosting services. The cloud technology emerged as a new alternative in the market. With cloud technology, many services, such as file hosting, data warehousing, and web hosting have begun to be offered by small and large companies such as Google and Amazon. Services which offered by these companies vary from a single service to multiple services under the cloud technology title. The 'cloud' concept refers to the externalities of the services offered and also refers to the infrastructure that companies with sufficient capabilities can create in their own structures. While there is interest in cloud technologies in Turkish literature, these studies deal with the conceptual dimensions of cloud solutions but do not assess their practical benefits in terms of enterprises. This study examines the positive and negative aspects of the cloud platform in terms of management information systems in order to fill this gap and it is revealed that the topics which considered as risk or negativity may not be valid for new ventures. In addition, the benefits of usage of the cloud technologies and its alternatives for enterprises especially for new ventures have been evaluated
