Weight Initialization for Convolutional Neural Networks Using Unsupervised Machine Learning

Description: The goal of this work is to improve the robustness and generalization of deep learning models, using a similar approach to the unsupervised "innate learning" strategy in visual development. A series of research studies are presented to demonstrate how an unsupervised machine learning efficient coding approach can create filters similar to the receptive fields of the primary visual cortex (V1) in the brain, and these filters are capable of pretraining convolutional neural networks (CNNs) to enab… more

Diffusion across the digital divide: Assessing use of the Connecticut Digital Library (ICONN) in K-12 schools in Connecticut.

Description: State digital libraries are manifestations of the diffusion of technology that has provided both access to and delivery of digital content. Whether the content is being accessed and used equitably in K-12 schools has not been assessed. Determining patterns of the diffusion of use across socioeconomic groups in K-12 schools may help measure the success of existing efforts to provide equitable access and use of digital content, and help guide policies and implementation to more effectively addr… more

Information Structures in Notated Music: Statistical Explorations of Composers' Performance Marks in Solo Piano Scores

Description: Written notation has a long history in many musical traditions and has been particularly important in the composition and performance of Western art music. This study adopted the conceptual view that a musical score consists of two coordinated but separate communication channels: the musical text and a collection of composer-selected performance marks that serve as an interpretive gloss on that text. Structurally, these channels are defined by largely disjoint vocabularies of symbols and words.… more

A Personal Documenation System for Scholars: A Tool for Thinking

Description: This exploratory research focused on a problem stated years ago by Vannevar Bush: "The problem is how creative men think, and what can be done to help them think." The study explored the scholarly work process and the use of computer tools to augment thinking. Based on a review of several related literatures, a framework of 7 major categories and 28 subcategories of scholarly thinking was proposed. The literature was used to predict problems scholars have in organizing their information, potent… more

Information Seeking in a Virtual Learning Environment

Description: Duplicating a time series study done by Kuhlthau and associates in 1989, this study examines the applicability of the Information Search Process (ISP) Model in the context of a virtual learning environment. This study confirms that students given an information seeking task in a virtual learning environment do exhibit the stages indicated by the ISP Model. The six-phase ISP Model is shown to be valid for describing the different stages of cognitive, affective, and physical tasks individuals pr… more

The Effects of Student-Perceived Instructor Demotivating Behaviors on Doctoral Students' Information Seeking Behaviors

Description: In their studies on student motivation in th4e 1990s, Gorham & Christophel and Christophel & Gorham found that students perceived their own demotivation to be caused by instructor behaviors. While there are studies that explore the topic of student demotivation and other studies that illustrate the great influence instructors have on student information seeking behaviors, research focusing on the connection between these two concepts is almost nonexistent. Using Gorham & Christophel's concept o… more

Data Quality Evaluation and Improvement for Machine Learning

Description: In this research the focus is on data-centric AI with a specific concentration on data quality evaluation and improvement for machine learning. We first present a practical framework for data quality evaluation and improvement, using a legal domain as a case study and build a corpus for legal argument mining. We first created an initial corpus with 4,937 instances that were manually labeled. We define five data quality evaluation dimensions: comprehensiveness, correctness, variety, class imbala… more

Twitter and the Affordance of Public Agenda-Setting: A Case Study of #MarchForOurLives

Description: In the traditional agenda-setting theory, the agenda-setters were the news media and the public has a minimal role in the process of agenda-setting, which makes the public a passive receiver located at the bottom in the top-down agenda-setting dynamics. This study claims that with the development of Information communication technologies, primarily social media, the networked public may be able to set their own agendas through connective actions, outside the influence of the news media agenda. … more

User-Centered Evaluation of the Quality of Blogs

Description: Blogs serve multiple purposes, resulting in several types of blogs that vary greatly in terms of quality and content. It is important to evaluate the quality of blogs, which requires appropriate evaluation criteria.
