Unsupervised Learning Trojan, Arturo Geigel
Unsupervised Learning Trojan, Arturo Geigel
CCE Theses and Dissertations
This work presents a proof of concept of an Unsupervised Learning Trojan. The Unsupervised Learning Trojan presents new challenges over previous work on the Neural network Trojan, since the attacker does not control most of the environment. The current work will presented an analysis of how the attack can be successful by proposing new assumptions under which the attack can become a viable one. A general analysis of how the compromise can be theoretically supported is presented, providing enough background for practical implementation development. The analysis was carried out using 3 selected algorithms that can cover a wide variety of …
Element Detection In Japanese Comic Book Panels, Toshihiro Kuboi
Element Detection In Japanese Comic Book Panels, Toshihiro Kuboi
Master's Theses
Comic books are a unique and increasingly popular form of entertainment combining visual and textual elements of communication. This work pertains to making comic books more accessible. Specifically, this paper explains how we detect elements such as speech bubbles present in Japanese comic book panels. Some applications of the work presented in this paper are automatic detection of text and its transformation into audio or into other languages. Automatic detection of elements can also allow reasoning and analysis at a deeper semantic level than what’s possible today. Our approach uses an expert system and a machine learning system. The expert …
Using A Model Of Temporal Latency To Improve Supervisory Control Of Human-Robot Teams, Kyle Lee Blatter
Using A Model Of Temporal Latency To Improve Supervisory Control Of Human-Robot Teams, Kyle Lee Blatter
Theses and Dissertations
When humans and remote robots work together on a team, the robots always interact with a human supervisor, even if the interaction is limited to occasional reports. Distracting a human with robotic interactions doesn't pose a problem so long as the inclusion of robots increases the team's overall effectiveness. Unfortunately, increasing the supervisor's cognitive load may decrease the team's sustainable performance to the point where robotic agents are more a liability than an asset. Present approaches resolve this problem with adaptive autonomy, where a robot changes its level of autonomy based on the supervisor's cognitive load. This thesis proposes to …

Social Sensing For Urban Crisis Management: The Case Of Singapore Haze, Philips Kokoh Prasetyo, Ming Gao, Ee Peng Lim, Christie N. Scollon

Sensing social media for trends and events has become possible as increasing number of users rely on social media to share information. In the event of a major disaster or social event, one can therefore study the event quickly by gathering and analyzing social media data. One can also design appropriate responses such as allocating resources to the affected areas, sharing event related information, and managing public anxiety. Past research on social event studies using social media often focused on one type of data analysis (e.g., hashtag clusters, diffusion of events, influential users, etc.) on a single social media data …
Faults Identification In Three-Phase Induction Motors Using Support Vector Machines, Rama Hammo
Faults Identification In Three-Phase Induction Motors Using Support Vector Machines, Rama Hammo
Master of Technology Management Plan II Graduate Projects
Induction motor is one of the most important motors used in industrial applications. The operating conditions may sometime lead the machine into different fault situations. The main types of external faults experienced by these motors are over loading, single phasing, unbalanced supply voltage, locked rotor, phase reversal, ground fault, under voltage and over voltage. The machine should be shut down when a fault is experienced to avoid damage and for the safety of the workers. Computer based relays monitor the machine and disconnect it during the faults. The relay logic used to identify these faults requires sophisticated signal processing techniques …
A Visualization And Simulation Tool That Will Generate Effective Patrolling Strategies To Protect The U.S. Borders From Illegal Intrusion Using Game Theoretic Methods And Models, Eric Gutierrez
Open Access Theses & Dissertations
In the recent decade, the United States Border Patrol has increased the presence of border security officers at points of entry along the U.S.- Mexico border. In response to this increased presence of border security officials at ports of entries, illegal intruders have rerouted their intrusions in between ports of entry, in harsher terrain areas of the U.S. (e.g., the Arizona desert). The U.S. Border Patrol could benefit from a tool that plans effective border patrolling routes, and helps border security officials to make risk-based decisions for resource allocation. We are currently developing a tool called Genetic Algorithm for a …
