Retrieval-Based Face Annotation By Weak Label Regularized Local Coordinate Coding, Dayong Wang, Steven C. H. Hoi, Ying He, Jianke Zhu

Research Collection School Of Computing and Information Systems

Retrieval-based face annotation is a promising paradigm in mining massive web facial images for automated face annotation. Such an annotation paradigm usually encounters two key challenges. The first challenge is how to efficiently retrieve a short list of most similar facial images from facial image databases, and the second challenge is how to effectively perform annotation by exploiting these similar facial images and their weak labels which are often noisy and incomplete. In this paper, we mainly focus on tackling the second challenge of the retrieval-based face annotation paradigm. In particular, we propose an effective Weak Label Regularized Local Coordinate …

A data sample of 2:5 million hadronic Z decays recorded over the period 1990 to 1994 in the ALEPH detector at LEP is used. The mean charge separation between event hemispheres containing the original quark and antiquark is measured for b b and cc events in subsamples selected by their long lifetimes or using fast D 's. The corresponding average charge separation for light quarks is measured in an inclusive sample from the …

Capir: Collaborative Action Planning With Intention Recognition, Nguyen T., Hsu D., Lee W., Tze-Yun Leong, Kaelbling L., Lozano-Perez T., Grant A.

Research Collection School Of Computing and Information Systems

We apply decision theoretic techniques to construct nonplayer characters that are able to assist a human player in collaborative games. The method is based on solving Markov decision processes, which can be difficult when the game state is described by many variables. To scale to more complex games, the method allows decomposition of a game task into subtasks, each of which can be modelled by a Markov decision process. Intention recognition is used to infer the subtask that the human is currently performing, allowing the helper to assist the human in performing the correct task. Experiments show that the method …

Sire: A Social Image Retrieval Engine, Steven C. H. Hoi, Pengcheng Wu

Research Collection School Of Computing and Information Systems

With the explosive growth of social media applications on the internet, billions of social images have been made available in many social media web sites nowadays. This has presented an open challenge of web-scale social image search. Unlike existing commercial web search engines that often adopt text based retrieval, in this demo, we present a novel web-based multimodal paradigm for large-scale social image retrieval, termed "Social Image Retrieval Engine" (SIRE), which effectively exploits both textual and visual contents to narrow down the semantic gap between high-level concepts and low-level visual features. A relevance feedback mechanism is also equipped to learn …

Analysis And Implementation Of Room Assignment Problem And Cannon's Algorithm On General Purpose Programmable Graphical Processing Units With Cuda, Harsh Vardhan Dwivedi

All Theses

General-purpose Graphics Processing Units (GP-GPU) has emerged as a popular computing paradigm for high-performance computing over the last few years. The increased interest in GP-GPUs for parallel computing mirrors the trend in general computing with the rise of multi-core processors as an alternative approach to increase processor performance. Many applications that were previously accelerated on distributed processing platforms with MPI or multithreaded techniques such as OpenMP are now being investigated to assess their performance on GP-GPU platforms. Since the GP-GPU platform is designed to give higher performance for parallel problems, applications on other parallel architectures are good candidates for performance …

Empirical Study: Failure Of Glass-To-Metal Seals During Shock Loading, William Horton

All Theses

The goal of this thesis was to determine the empirical failure mechanisms and sequence of cartridge actuated devices (CADs) experiencing failure of the glass-to-metal (G/M) seal. Impact loading was conducted with a drop weight machine at room temperature and 300¡F, and then empirically analyzed with high speed video. Resulting peak overload force, shear stress, and impulse were all calculated. The room temperature samples were found to absorb twice the impulse upon failure as the elevated temperature G/M seals. Closed-form and three-dimensional finite element analysis was used to determine the stress state and deformation upon loading. Furthermore, high speed data was …

Do The Ethics Of Authorship Matter?: Exploring The Implications Of The Office Of Research Integrity's Narrow Definition Of Research Misconduct, Caroline Linvill

All Theses

Over the past 25 years, federal government entities have become involved in defining and regulating misconduct in scientific research. Consistently, these definitions of research misconduct forbid three key actions--falsification, fabrication, and plagiarism--but do not take into account other professional communication issues, mainly authorship. This lack of acknowledgement and regulation of authorship--particularly from the Office of Research Integrity, the nation's highest research ethics body--seems to imply and communicate that the ethics of authorship are not important in science. However, this thesis demonstrates, through rhetorical, historical and interview research, that authorship ethics do matter to scientists; in fact, authorship is a leading …

Laminar Flame Speed Estimation From Experimental Data Using A Quasi-Dimensional Turbulent Flame Entrainment Combustion Simulation For Spark Ignition Engines, Akash Desai

All Theses

The goal of this research is to develop a thermodynamic simulation of spark-ignition engine combustion that uses a predictive burn-rate model. Previously done thermodynamic engine simulations in MATLAB are based on a specified burn rate model. Also, the effect of turbulence parameters on the rate of mass burn up is not considered. A predictive burn rate model is necessary to study the effect of different fuels on spark ignition engine combustion. The effect of laminar flame speed and turbulent intensity on combustion is difficult to assess experimental due to the difficulty in the measurement of these two variables. Thus, the …

Optimized Built-In Self-Test Technique For Caen-Based Nanofabric Systems, Sambhav Kundaikar, Maciej Zawodniok

Electrical and Computer Engineering Faculty Research & Creative Works

We propose a built-in self-test (BIST) technique for testing and diagnosis of molecular electronic based nano fabrics. the nano fabric architectures are reconfigurable in nature thus making it possible to utilize general methods similar to those employed for testing of FPGAs. However, a high defect rate in nano fabrics renders the traditional techniques ill-suited. Moreover, the nano blocks offer potential for using a partially damaged nano block due to inherent redundancy of the architecture. This paper presents the design and analysis of testing configurations and optimization scheme that minimizes testing time while improving the utilization of the nano fabric. the …

On The Linear Precoder Design For Mimo Channels With Finite-Alphabet Inputs And Statistical Csi, Weiliang Zeng, Chengshan Xiao, Mingxi Wang, Jianhua Lu

Electrical and Computer Engineering Faculty Research & Creative Works

This paper investigates the linear precoder design that maximizes the average mutual information of multiple-input multiple-output channels with finite-alphabet inputs and statistical channel state information known at the transmitter. This linear precoder design is an important open problem and is extremely difficult to solve: First, average mutual information lacks closed-form expression and involves complicated computations; Second, the optimization problem over precoder is nonconcave. This study explores the solution to this problem and provides the following contributions: 1) a closed-form lower bound of average mutual information is derived. It achieves asymptotic optimality at low and high signal-to-noise ratio regions and, with …

Using Information Technology To Forge Connections In An Extension Service Project, Sandra B. Schneider, Donna-Jean P. Brock, Crystal Duncan Lane, Peggy S. Meszaros, Barbara B. Lockee

Journal of Extension

A hybrid Extension project is introduced that uses a traditional Extension delivery model without the complete infrastructure of Cooperative Extension Services. The absence of this local organizational support and infrastructure necessitates new thinking regarding how Information Technology (IT) can support this project and hybrid Extension projects in general. The reciprocal relationship between offline and online tasks and how an Internet portal can serve as a centralized location for project continuity is offered as one solution. How IT facilitates the implementation of hybrid Extension projects such as this one can further promote the interdisciplinary adoption of the Extension model.

Extension Is Unpopular—On The Internet, Heidi B. Rader

Journal of Extension

The first Extension-authored link in Google Search (2011a) for "how to garden" was ranked an abysmal 82nd. Worse, Internet users selected the top-ranked site significantly more often than they selected the second-ranked one, and they rarely selected any site ranked lower than #10 (Granka, Joachims, & Gay, 2004). An Extension-commissioned poll in Alaska found only 16% of the "Net Generation" had even heard of Extension, compared with 73% of those 60 years or older (Dittman Research & Communications Corporation, 2010). Extension's websites are so unpopular, those who seek research-based, unbiased information will likely not find it. This article proposes solutions.

The Role Of Coastal Plant Community Response To Climate Change: Implications For Restoring Ecosystem Resiliency, Hannah June Kalk

Theses

Accelerated sea-level rise and increased intensity of tropical storm events have challenged the conventional approaches to conservation and restoration of coastal ecosystems. In coastal communities, where survival will depend largely on the ability of species to adapt to rapidly shifting conditions or become established farther inland, historic assemblages may be lost. Seed banks may be an important component of resilience and recovery in response to altered inundation regimes, should they contain species able to adapt or migrate inland. This study assess the ability of seed banks to act as ecological buffers to storm surge disturbances and to instill ecological resilience …

Expanding The Love Out Loud Campaign: The Utility Of Online Public Relations Practices For Nonprofit Organizations Focused On Reducing Suicide Among College Students, Kristen Marie Weilenmann

Journalism

Nonprofit organizations and movements geared toward suicide prevention, a somewhat taboo subject in American culture, are oftentimes confronted with the dilemma of lacking adequate funding to meet their goals. This essay focuses on the expansion of one such movement, the Love Out Loud Campaign, which took shape at California Polytechnic State University, San Luis Obispo in 2011, in hopes of encouraging open communication and positivity to dissuade those at risk for suicide from taking their own lives. The campaign began as the senior project of a group of students who graduated in June of 2011. Unfortunately, the movement lost steam …

Poly Press Association: Eliminating Silos Through Online Collaboration, Sarah Parr

Journalism

The silo effect creates boundaries and separation within parts of a larger organized entity. In order to overcome the silo effect, the entity must seek holistic ways to unite the parts. This paper addresses the need for a collective that serves students from all three concentrations in Cal Poly’s journalism department: news editorial, public relations, and broadcast. The collective, Poly Press Association, will feature student work, and provide comprehensive tutorials, internship opportunities/ratings, and student blogs. The Poly Press Association aims to help eliminate any boundaries between the three concentrations.

Embodied Compositionality, A Cangelosi

School of Engineering, Computing and Mathematics

Luc Steels [10] provides a comprehensive overview of the key theoretical issues on the cultural evolution of language and of the contribution of computational and robotics models to the study of the social emergence of language in societies of interactive agents. In this short commentary, I would like to extend the discussion by focusing: (i) on the origins of the hierarchical structure of language, as grounded in the embodied compositional nature of motor representations and skills such as those of object manipulation; and (ii) on the interaction of genetic and cultural evolution processes in language evolution.
