The text will be the third edition of Languages and Machines: An Introduction to the Theory of Computer Science, by Thomas Sudkamp.
Wraps – A System For Determining The Probability Of Prokaryotic Protein Annotation Correctness, Benjamin K. Nelson
Wraps – A System For Determining The Probability Of Prokaryotic Protein Annotation Correctness, Benjamin K. Nelson
Student Work
Advances in sequencing technology have resulted in the sequencing of whole genomes from many simple organisms such as fungi and bacteria, while allowing the assembly of much more complex genomes like humans and chimpanzees. Consequently, association of segments of newly sequenced genomes to specific function (i.e. annotation) is being completed by comparative study of protein coding regions from previously annotated genome data. While this is an ideal procedure to process and annotate huge number of available genomic sequences, this approach can potentially lead to propagating erroneous annotation in a public sequence repository and vastly diminish the integrity of these new …
Creating A Semantic Graph From Wikipedia, Ryan Tanner
Creating A Semantic Graph From Wikipedia, Ryan Tanner
Computer Science Honors Theses
With the continued need to organize and automate the use of data, solutions are needed to transform unstructred text into structred information. By treating dependency grammar functions as programming language functions, this process produces \property maps" which connect entities (people, places, events) with snippets of information. These maps are used to construct a semantic graph. By inputting Wikipedia, a large graph of information is produced representing a section of history. The resulting graph allows a user to quickly browse a topic and view the interconnections between entities across history.
Random Number Generation: Types And Techniques, David F. Dicarlo
Random Number Generation: Types And Techniques, David F. Dicarlo
Senior Honors Theses
What does it mean to have random numbers? Without understanding where a group of numbers came from, it is impossible to know if they were randomly generated. However, common sense claims that if the process to generate these numbers is truly understood, then the numbers could not be random. Methods that are able to let their internal workings be known without sacrificing random results are what this paper sets out to describe. Beginning with a study of what it really means for something to be random, this paper dives into the topic of random number generators and summarizes the key …

Message Passing Algorithms For Map Estimation Using Dc Programming, Akshat Kumar, Shlomo Zilberstein, Marc Toussaint
Message Passing Algorithms For Map Estimation Using Dc Programming, Akshat Kumar, Shlomo Zilberstein, Marc Toussaint
Research Collection School Of Computing and Information Systems
We address the problem of finding the most likely assignment or MAP estimation in a Markov random field. We analyze the linear programming formulation of MAP through the lens of difference of convex functions (DC) programming, and use the concave-convex procedure (CCCP) to develop efficient message-passing solvers. The resulting algorithms are guaranteed to converge to a global optimum of the well-studied local polytope, an outer bound on the MAP marginal polytope. To tighten the outer bound, we show how to combine it with the mean-field based inner bound and, again, solve it using CCCP. We also identify a useful relationship …
Face Detection From Images Using Support Vector Machine, Parin M. Shah
Face Detection From Images Using Support Vector Machine, Parin M. Shah
Master's Projects
Detection of patterns in images using classifiers is one of the most promising topics of research in the field of computer vision. A large number of practical applications for face detection exist and contemporary work even suggests that any specialized detectors can be approximated by using fast detection classifiers. In this project, I have developed an algorithm which will detect face from the input image with less false detection rate using combined effects of computer vision concepts. This algorithm utilizes the concept of recognizing skin color, detecting edges and extracting different features from face. The result is supported by the …

Text Summarization, Youn S. Kim
Master's Projects
With the overwhelming amount of textual information available in electronic formats on the web, there is a need for an efficient text summarizer capable of condensing large bodies of text into shorter versions while keeping the relevant information intact. Such a technology would allow users to get their information in a shortened form, saving valuable time. Since 1997, Microsoft Word has included a summarizer for documents, and currently there are companies that summarize breaking news and send SMS for mobile phones. I wish to create a text summarizer to provide condensed versions of original documents. My focus is on blogs, …
Optimizing A Web Search Engine, Ravi Inder Singh Dhillon
Optimizing A Web Search Engine, Ravi Inder Singh Dhillon
Master's Projects
Search Engine queries often have duplicate words in the search string. For example user searching for "pizza pizza" a popular brand name for Canadian pizzeria chain. An efficient search engine must return the most relevant results for such queries. Search queries also have pair of words which always occur together in the same sequence, for example “honda accord”, “hopton wafers”, “hp newwave” etc. We will hereafter refer to such pair of words as bigrams. A bigram can be treated as a single word to increase the speed and relevance of results returned by a search engine that is based on …

Session Based Music Recommendation Using Singular Value Decomposition (Svd), Ruchit V. Mehta
Master's Projects
Technology in the modern world has over-simplified the access to information. At a click of a button we have volumes of music accessible on the Internet. Paradoxically, the abundance of available options has only made music discovery and recommendations a complex problem to solve. With huge collections of songs in the online digital libraries, finding a song or an artist is not a problem. However, an actual problem is what to look for that will intuitively satisfy a user’s need. There exists multitude of recommendation algorithms, but many of them do not consider the contextual information in which a user …
Actor-Based Concurrency In Newspeak 4, Nikolay Botev
Actor-Based Concurrency In Newspeak 4, Nikolay Botev
Master's Projects
Actors are a model of computation invented by Carl Hewitt in the 1970s. It has seen a resurrection of mainstream use recently as a potential solution to the latency and concurrency that are quickly rising as the dominant challenges facing the software industry. In this project I explored the history of the actor model and a practical implementation of actor-based concurrency tightly integrated with non-blocking futures in the E programming language developed by Mark Miller. I implemented an actor-based concurrency framework for Newspeak that closely follows the E implementation and includes E-style futures and deep integration into the programming language …

Electrocardiogram (Ecg/Ekg) Using Fpga, Vaibhav Desai
Master's Projects
FPGAs (Field Programmable Gate Arrays) are finding wide acceptance in medical systems for their ability for rapid prototyping of a concept that requires hardware/software co-design, for performing custom processing in parallel at high data rates and be programmed in the field after manufacturing. Based on the market demand, the FPGA design can be changed and no new hardware needs to be purchased as was the case with ASICs (Application Specific Integrated Circuit) and CPLDs (Complex Programmable Logic Device). Medical companies can now move over to FPGAs saving cost and delivering highly-efficient upgradable systems. ECG (Electrocardiogram) is considered to be a …
Hidden Markov Models For Software Piracy Detection, Shabana Kazi
Hidden Markov Models For Software Piracy Detection, Shabana Kazi
Master's Projects
The unauthorized copying of software is often referred to as software piracy. Soft- ware piracy causes billions of dollars of annual losses for companies and governments worldwide. In this project, we analyze a method for detecting software piracy. A meta- morphic generator is used to create morphed copies of a base piece of software. A hidden Markov Model is trained on the opcode sequences extracted from these mor- phed copies. The trained model is then used to score suspect software to determine its similarity to the base software. A high score indicates that the suspect software may be a modified …
Metamorphic Worm That Carries Its Own Morphing Engine, Sudarshan Madenur Sridhara
Metamorphic Worm That Carries Its Own Morphing Engine, Sudarshan Madenur Sridhara
Master's Projects
Metamorphic malware changes its internal structure across generations, but its functionality remains unchanged. Well-designed metamorphic malware will evade signature detection. Recent research has revealed techniques based on hidden Markov models (HMMs) for detecting many types of metamorphic malware, as well as techniques for evading such detection. A worm is a type of malware that actively spreads across a network to other host systems. In this project we design and implement a prototype metamorphic worm that carries its own morphing engine. This is challenging, since the morphing engine itself must be morphed across replications, which imposes significant restrictions on the structure …

Keyword Search In Social Networks, Vijeth Patil
Master's Projects
People often tend to ask their friends whenever they want some information related to topics like events, restaurants, or movies as majority of the search engines do not yield the desired results which people are seeking [1]. At present, majority of the current Open Source search engines like those based on Nutch also do not yield desired or expected results. Popular search engine, Google recently incorporated the feature of providing information from your social circle but only limited to Google Plus in your search results. On the other hand, micro blogging site Twitter has emerged as a vital source of …

It is useful to create personalized web crawls, and search through them later on to see the archived content and compare it with current content to see the difference and evolution of that portion of web. It is also useful for searching through the portion of web you are interested in an offline mode without need of going online. To accomplish that, in this project I focus towards indexing of the archive (ARC) files generated by an open source web-crawler named Heritrix. I developed a Java module to perform indexing on these archive files. I used large set of archive …
Online Collaborative Editor, Aditya Rao
Online Collaborative Editor, Aditya Rao
Master's Projects
“Online collaborative editor” is a node.js based browser application that provides real time collaborative editing of files and improves pair programming. Current real time editors fail to provide simultaneous viewing and editing of files within the server and results in a complex version controlling system. Such systems are also vulnerable to deadlocks and race conditions. This project provides a platform for real time collaborative editors, which can support simultaneous editing and viewing of files and handle concurrency problems by using locking mechanism. The experiment results showed that node.js platform provides good performance for collaborative editing.

Knowledge Engineering In Search Engines, Yun-Chieh Lin
Master's Projects
With large amounts of information being exchanged on the Internet, search engines have become the most popular tools for helping users to search and filter this information. However, keyword-based search engines sometimes obtain information, which does not meet user’ needs. Some of them are even irrelevant to what the user queries. When the users get query results, they have to read and organize them by themselves. It is not easy for users to handle information when a search engine returns several million results. This project uses a granular computing approach to find knowledge structures of a search engine. The project …
