Hi, Magic Closet, Tell Me What To Wear!, Si Liu, Tam Nguyen, Jiashi Feng, Meng Wang, Shuicheng Yan

Computer Science Faculty Publications

In this demo, we present a practical system, "magic closet," for automatic occasion-oriented clothing pairing. Given a user-input occasion, e.g., wedding or shopping, the magic closet intelligently and automatically pairs the user-specified reference clothing (upper body or lower body) with the most suitable one from online shops. Two key criteria are explicitly considered for the magic closet system. One criterion is to dress properly, e.g., compared to suit pants, it is more decent to wear a cocktail dress for a banquet occasion. The other criterion is to dress aesthetically, e.g., a red T-shirt matches better with white pants than with …

Sense Beauty Via Face, Dressing, And/Or Voice, Tam Nguyen, Si Liu, Bingbing Ni, Jun Tan, Yong Rui, Shuicheng Yan

Computer Science Faculty Publications

Discovering the secret of beauty has been the pursuit of artists and philosophers for centuries. Nowadays, the computational model for beauty estimation has been actively explored in computer science community, yet with the focus mainly on facial features. In this work, we perform a comprehensive study of female attractiveness conveyed by single/multiple modalities of cues, i.e., face, dressing, and/or voice, and aim to uncover how different modalities individually and collectively affect the human sense of beauty. To this end, we collect the first Multi-Modality Beauty (M²B) dataset in the world for female attractiveness study, which is thoroughly annotated …

Principles For Conducting Critical Realist Case Study Research In Information Systems, Donald E. Wynn, Clay K. Williams

MIS/OM/DS Faculty Publications

Critical realism is emerging as a viable philosophical paradigm for conducting social science research, and has been proposed as an alternative to the more prevalent paradigms of positivism and interpretivism. Few papers, however, have offered clear guidance for applying this philosophy to actual research methodologies. Under critical realism, a causal explanation for a given phenomenon is inferred by explicitly identifying the means by which structural entities and contextual conditions interact to generate a given set of events. Consistent with this view of causality, we propose a set of methodological principles for conducting and evaluating critical realism-based explanatory case study research …

Dynamic Diffusion For Congestion Avoidance In Wireless Sensor Networks, Sri Divya Deenadayalan

Boise State University Theses and Dissertations

Wireless Sensor Networks (WSNs) are employed for either continuous monitoring or event detection in the target area of interest. In event-driven applications, it is critical to report the detected events in the area, and with sudden bursts of traffic possible due to spatially-correlated events or multiple events, the data loss due to congestion will result in information loss or delayed arrival of the sensed information. Congestion control techniques detect congestion and attempt to recover from packet losses due to congestion, but they cannot eliminate or prevent the occurrence of congestion. Congestion avoidance techniques employ proactive measures to alleviate future congestion …

Real Time Face Hallucination For Recognition, Alexander Knaust, Olac Fuentes

COURI Symposium Abstracts, Summer 2012

Low resolution video and images are a common hindrance in recognition of people or enjoyment of a communication service, but are often necessary due to high hardware costs or low bandwidth availability. In particular, surveillance images of faces are commonly of too low a resolution to recognize reliably, hampering their purpose. Face Hallucination consists of Super-Resolution techniques to enhance the images of faces beyond what can be achieved by standard interpolation techniques. Unfortunately, the facial hallucination algorithms in present literature are slow, taking up to an hour with modestly sized images. We propose optimizations of the Eigentransform Super Resolution algorithm …

Prosody-Based Query-By-Example Spoken Utterance Retrieval, Steven D. Werner, Nigel G. Ward

COURI Symposium Abstracts, Summer 2012

Current spoken dialogue retrieval systems are almost entirely lexically based, using automatic transcription by imperfect speech recognition technology. Once audio is reduced to text, little more than existing text search methods are used to retrieve results. However, spoken dialogue contains rich latent prosodic information about dialogue activities - such as agreeing, arguing, deciding, planning, storytelling, showing surprise - and this extra information can often be relevant to the searchers aims. Searching for similar speech acts rather then similar words enables similar contextual results, returning points where the speaker had the same sentiment during a topic. Previous research yielded 76 dimensions …

Geometric Programming Subject To System Of Fuzzy Relation Inequalities, Elyas Shivanian, Mahdi Keshtkar, Esmaile Khorram

Applications and Applied Mathematics: An International Journal (AAM)

In this paper, an optimization model with geometric objective function is presented. Geometric programming is widely used; many objective functions in optimization problems can be analyzed by geometric programming. We often encounter these in resource allocation and structure optimization and technology management, etc. On the other hand, fuzzy relation equalities and inequalities are also used in many areas. We here present a geometric programming model with a monomial objective function subject to the fuzzy relation inequality constraints with maxproduct composition. Simplification operations have been given to accelerate the resolution of the problem by removing the components having no effect on …

Numerical Solution Of Interval And Fuzzy System Of Linear Equations, Suparna Das, S. Chakraverty

Applications and Applied Mathematics: An International Journal (AAM)

A system of linear equations, in general is solved in open literature for crisp unknowns, but in actual case the parameters (coefficients) of the system of linear equations contain uncertainty and are less crisp. The uncertainties may be considered in term of interval or fuzzy number. In this paper, a detail of study of linear simultaneous equations with interval and fuzzy parameter (triangular and trapezoidal) has been performed. New methods have been proposed for solving such systems. First, the methods have been tested for known problems viz. a circuit analysis solved in the literature and the results are found to …

Wireless Sensor Network For Wine Fermentation, Kerry Scharfglass, Andrew Lehmer

Computer Engineering

This project implements an automated temperature monitoring system for wine fermentation which is affordable, easy to use, and scalable to typical small winery setups. To realize these requirements, we implemented the system as a wireless sensor network utilizing commercial off-the-shelf hardware. Temperature and system diagnostic information is communicated wirelessly in a peer-to-peer network topology such that all information flows toward an aggregating server. The server makes the temperature information available over the Internet via a web application and alerts the winemaker by email when the temperature has left acceptable bounds that the winemaker may configure. This project also involved materials …

Teaching Introductory Programming Concepts: A Comparison Of Scratch And Arduino, Anne Beug

Master's Theses

Computing has become an integral part of modern America. The Bureau of Labor Statistics estimates that between 2008 and 2018, the United States will have 1.4 million job openings in computing fields [1]. Since the early 2000's (just after the "dot com bust"), the number of students enrolled in computing majors (Computer Science, Computer Engineering, etc.) dropped precipitously by over 50%, only starting to rise again in 2009 [2]. One way to rectify to this gap between demand and supply is to start training students in computational thinking during high school. While the Computer Science Advanced Placement AB test has …

Software For Estimation Of Human Transcriptome Isoform Expression Using Rna-Seq Data, Kristen Johnson

LSU New Orleans Theses and Dissertations

The goal of this thesis research was to develop software to be used with RNA-Seq data for transcriptome quantification that was capable of handling multireads and quantifying isoforms on a more global level. Current software available for these purposes uses various forms of parameter alteration in order to work with multireads. Many still analyze isoforms per gene or per researcher determined clusters as well. By doing so, the effects of multireads are diminished or possibly wrongly represented. To address this issue, two programs, GWIE and ChromIE, were developed based on a simple iterative EM-like algorithm with no parameter manipulation. These …

Defining Industry Expectations And Misconceptions Of Art And Technology Co-Creativity, Vanessa C. Brasfield

Department of Computer Graphics Technology Degree Theses

The primary purpose of this study was to establish whether or not students and industry professionals share the same views about what students should be learning in animation education, what skills are necessary, and whether or not students graduating with a bachelor’s degree would be adequately prepared for an entry level position. To establish where misconceptions lie, surveys were issued to three groups: undergraduate students, post-graduate students, and industry professionals. These surveys were then analyzed using paired t-test for validation and question relevance, and ANOVA models to establish whether or not groups shared viewpoints. These data established significance within the …

Stochastic Analysis Of Horizontal Ip Scanning, Derek Leonard, Zhongmei Yao, Xiaoming Wang, Dmitri Loguinov

Computer Science Faculty Publications

Intrusion Detection Systems (IDS) have become ubiquitous in the defense against virus outbreaks, malicious exploits of OS vulnerabilities, and botnet proliferation. As attackers frequently rely on host scanning for reconnaissance leading to penetration, IDS is often tasked with detecting scans and preventing them. However, it is currently unknown how likely an IDS is to detect a given Internet-wide scan pattern and whether there exist sufficiently fast scan techniques that can remain virtually undetectable at large-scale. To address these questions, we propose a simple analytical model for the window-expiration rules of popular IDS tools (i.e., Snort and Bro) and utilize a …

On Superposition Of Heterogeneous Edge Processes In Dynamic Random Graphs, Zhongmei Yao, Daren B. H. Cline, Dmitri Loguinov

Computer Science Faculty Publications

This paper builds a generic modeling framework for analyzing the edge-creation process in dynamic random graphs in which nodes continuously alternate between active and inactive states, which represent churn behavior of modern distributed systems. We prove that despite heterogeneity of node lifetimes, different initial out-degree, non-Poisson arrival/failure dynamics, and complex spatial and temporal dependency among creation of both initial and replacement edges, a superposition of edge-arrival processes to a live node under uniform selection converges to a Poisson process when system size becomes sufficiently large. Due to the convoluted dependency and non-renewal nature of various point processes, this result significantly …

Application Of Inter-Die Rank Statistics In Defect Detection, Vivek Bakshi

Dissertations and Theses

This thesis presents a statistical method to identify the test escapes. Test often acquires parametric measurements as a function of logical state of a chip. The usual method of classifying chips as pass or fail is to compare each state measurement to a test limit. Subtle manufacturing defects are escaping the test limits due to process variations in deep sub-micron technologies which results in mixing of healthy and faulty parametric test measurements. This thesis identifies the chips with subtle defects by using rank order of the parametric measurements. A hypothesis is developed that a defect is likely to disturb the …

Maximizing Network Lifetime On The Line With Adjustable Sensing Ranges, Amotz Bar-Noy, Ben Baumer

Statistical and Data Sciences: Faculty Publications

Given n sensors on a line, each of which is equipped with a unit battery charge and an adjustable sensing radius, what schedule will maximize the lifetime of a network that covers the entire line? Trivially, any reasonable algorithm is at least a 1/2-approximation, but we prove tighter bounds for several natural algorithms. We focus on developing a linear time algorithm that maximizes the expected lifetime under a random uniform model of sensor distribution. We demonstrate one such algorithm that achieves an average-case approximation ratio of almost 0.9. Most of the algorithms that we consider come from a family based …

Open Source Classroom Polling (Interactive Response) Facility, Ronald I. Greenberg

Computer Science: Faculty Publications and Other Works

The contents of the UNIX directory resulting from unzipping the .zip file provide a demonstration of a simple polling facililty that instructors can use in class any time that students have access to a web browser. This is a good way to have students work problems and see to what extent they are converging towards correct answers.

Unlike other polling facilities, this one is completely free without any restrictions on number of simultaneous users, etc. It also allows a feature most polling facilities do not in that it may be used for completely free-form answers, and the instructor can still …

Strongly Complete Logics For Coalgebras, Alexander Kurz, Jiří Rosický

Engineering Faculty Articles and Research

Coalgebras for a functor model different types of transition systems in a uniform way. This paper focuses on a uniform account of finitary logics for set-based coalgebras. In particular, a general construction of a logic from an arbitrary set-functor is given and proven to be strongly complete under additional assumptions. We proceed in three parts.

Part I argues that sifted colimit preserving functors are those functors that preserve universal algebraic structure. Our main theorem here states that a functor preserves sifted colimits if and only if it has a finitary presentation by operations and equations. Moreover, the presentation of the …

The Design, Implementation, And Evaluation Of A Pointing Device For A Wearable Computer, Andres Calvo, Gregory Burnett, Victor Finomore, Saverio Perugini

Computer Science Faculty Publications

U.S. Air Force special tactics operators at times use small wearable computers (SWCs) for mission objectives. The primary pointing device of a SWC is either a touchpad or trackpoint, embedded into the chassis of the SWC. In situations where the user cannot directly interact with these pointing devices, the utility of the SWC is decreased. We developed a pointing device called the G3 that can be used for SWCs used by operators. The device utilizes gyroscopic sensors attached to the user’s index finger to move the computer cursor according to the angular velocity of his finger. We showed that, as …

Ancillary Service Capacity Optimization For Both Electric Power Suppliers And Independent System Operator, Lijian Chen, Dengfeng Sun, Guang Li

MIS/OM/DS Faculty Publications

Ancillary Services (AS) in electric power industry are critical to support the transmission of energy from generators to load demands while maintaining reliable operation of transmission systems in accordance with good utility practice. The ancillary services are procured by the independent system operator (ISO) through a process called the market clearing process which can be modeled by the partial equilibrium from the ends of ISO. There are two capacity optimization problems for both Market participants (MP) and Independent System Operator (ISO). For a market participant, the firm needs to determine the capacity allocation plan for various AS to pursue operating …

Irish Cios’ Influence On Technology Innovation And It-Business Alignment, Harvey Enns, Joseph J. Mcdonagh

MIS/OM/DS Faculty Publications

Technology is the driving force behind many of today’s new products, services, and cost-cutting measures. However, there are gaps in our understanding about how technological innovation is fostered and nurtured in organizations.

Part of the answer is to examine how Chief Information Officers (CIOs) exercise influence regarding technological innovation in organizations. This is particularly important since the CIO is the head of technology in organizations, an important source of technological innovation. This article draws on an established executive influence framework to demonstrate how Irish CIOs are able to solidify Information Technology’s (IT’s) contribution to technological innovation via relational means. Most …

Significantly Reducing The Processing Times Of High-Speed Photometry Data Sets Using A Distributed Computing Model, Paul Doyle, Fredrick Mtenzi, Niall Smith, Adrian Collins, Brendan O'Shea

Other

The scientific community is in the midst of a data analysis crisis. The increasing capacity of scientific CCD instrumentation and their falling costs is contributing to an explosive generation of raw photometric data. This data must go through a process of cleaning and reduction before it can be used for high precision photometric analysis. Many existing data processing pipelines either assume a relatively small dataset or are batch processed by a High Performance Computing centre. A radical overhaul of these processing pipelines is required to allow reduction and cleaning rates to process terabyte sized datasets at near capture rates using …

Parsing The Relationship Between Baserunning And Batting Abilities Within Lineups, Ben S. Baumer, James Piette, Brad Null

Statistical and Data Sciences: Faculty Publications

A baseball team's offensive prowess is a function of two types of abilities: batting and baserunning. While each has been studied extensively in isolation, the effects of their interaction is not well understood. We model offensive output as a scalar function f of an individual player's batting and baserunning profile z. Each of these profiles is in turn estimated from Retrosheet data using heirarchical Bayesian models. We then use the SimulOutCome simulation engine as a method to generate values of f(z) over a fine grid of points. Finally, for each of several methods of taking the extra base, we graphically …

Morality In The Virtual Space: Applying Moral Philosophy To Digital Worlds, James O'Sullivan

Theses

Since the turn of the century and the dawn of the digital age, online communities have witnessed significant growth in their importance. Significant numbers of virtual environments now exist, within which millions of individuals interact socially and economically, engaged fully in what is equivalent to a physical encounter, the only differences being the virtual representations through which they interact, and the physical security that this representation affords them. Though physically absent, individuals are fully engaged psychologically, and thus open to the same ethical dilemmas presented through reality. Application of real-world moral codes is encumbered by the existence of what 1 …
