Incremental Learning with Large Datasets

Incremental Learning with Large Datasets

Date: May 2012
Creator: Giritharan, Balathasan
Description: This dissertation focuses on the novel learning strategy based on geometric support vector machines to address the difficulties of processing immense data set. Support vector machines find the hyper-plane that maximizes the margin between two classes, and the decision boundary is represented with a few training samples it becomes a favorable choice for incremental learning. The dissertation presents a novel method Geometric Incremental Support Vector Machines (GISVMs) to address both efficiency and accuracy issues in handling massive data sets. In GISVM, skin of convex hulls is defined and an efficient method is designed to find the best skin approximation given available examples. The set of extreme points are found by recursively searching along the direction defined by a pair of known extreme points. By identifying the skin of the convex hulls, the incremental learning will only employ a much smaller number of samples with comparable or even better accuracy. When additional samples are provided, they will be used together with the skin of the convex hull constructed from previous dataset. This results in a small number of instances used in incremental steps of the training process. Based on the experimental results with synthetic data sets, public benchmark data sets from ...

African Refugee Parents' Involvement in Their Children's Schools: Barriers and Recommendations for Improvement

African Refugee Parents' Involvement in Their Children's Schools: Barriers and Recommendations for Improvement

Access: Use of this item is restricted to the UNT Community.
Date: December 2009
Creator: Githembe, Purity Kanini
Description: The purpose of this study was to examine involvement of African refugee parents in the education of their elementary school children. The setting of the study was Northern and Southern Texas. African refugee parents and their children's teachers completed written surveys and also participated in interviews. In the study's mixed-method design, quantitative measures provided data about parent involvement at home, parent involvement at school, frequency of parent-teacher contact, quality of parent-teacher relationship, parent endorsement of children's schools, and barriers to parent involvement. Qualitative data from the open-ended questions provided data on barriers and strategies to improve involvement. Sixty-one African refugee parents responded to the survey and also participated in an in-depth face-to-face or telephone interview. Twenty teacher participants responded to an online survey. Quantitative data gathered from the parent and teacher surveys were analyzed using frequency distributions and analyses of variance. Qualitative data were analyzed by summarizing and sorting information into different categories using Weft QDA, an open-source qualitative analysis software. From these data, I identified barriers to African refugee parent involvement in their children's schools, as well as challenges that teachers face as they try to involve African refugee parents. Results of analyses of variance revealed statistically significant differences ...

The impact of the core knowledge curriculum at the junior high level as it relates to performance on the Texas Assessment of Knowledge and Skills.

The impact of the core knowledge curriculum at the junior high level as it relates to performance on the Texas Assessment of Knowledge and Skills.

Date: May 2008
Creator: Givens, Toby D.
Description: The purpose of this study was to determine the impact of the comprehensive school reform model core knowledge on the reading achievement of eighth grade students located in a suburban north Texas school district. The data compared the mean scores on the Texas Assessment of Knowledge and Skills of students attending the experimental core knowledge school with the control school that did not use the core knowledge curriculum. Students from both schools were compared for student achievement gains overall as well as several other categories. The study also used a qualitative survey that asked key faculty members at both schools questions regarding levels of curriculum implementation, staff knowledge of curriculum, etc. The data showed no significant differences between student achievement scores at the experimental school compared with students at the control school. However, the study found that the type of standardized test seems to have an impact on whether students in a core knowledge curriculum show higher achievement than students in a traditional curriculum. Students in a core knowledge curriculum show higher achievement on norm-referenced standardized tests when compared with students not attending a core knowledge school. When taking a criterion-referenced test such as the Texas Assessment of Knowledge and ...

Musical Borrowing in the Choral Music of Andrew Rindfleisch

Musical Borrowing in the Choral Music of Andrew Rindfleisch

Date: December 2015
Creator: Glann, Kerry
Description: American composer Andrew Rindfleisch (b. 1963) has contributed twenty-one pieces to the repertoire of contemporary choral literature to date. His works have been commissioned, premiered, and recorded by notable choral ensembles and performed in significant venues around the country. Influenced by his own early choral singing experience in his native Wisconsin, much of Rindfleisch’s choral music is infused with influences of the music of earlier composers and choral idioms. With these works, Rindfleisch participates in a long-standing trend in choral composition of looking to the musical past for inspiration and procedure while writing in a contemporary harmonic vocabulary, and his efforts can be evaluated through the lens of a study of musical borrowing. Through a case study of five of Rindfleisch’s choral works – “In manus tuas,” “Mille regretz,” “Psalm,” “Anthem,” and “Graue Liebesschlangen” – this document identifies common characteristics of Rindfleisch’s choral music and demonstrates his uses of musical borrowing and allusion. The influence of Renaissance polyphony, Debussy, Brahms, and German expressionism is revealed.

The Influence of Interorganizational Trust, Individualism and Collectivism, and Superordinate Goal of JIT/TQM on Interorganizational Cooperation: An Exploratory Analysis of Institutions in Mexico

Date: December 1998
Creator: Glaser-Segura, Daniel A. (Daniel Armand)
Description: Since their introduction to the United States from Japan in the 1980s, inter-organizational cooperation practices between buyers and suppliers have provided lower costs, shorter development and production cycles, and higher levels of quality and productivity. Many studies of interorganizational cooperation have relied on transaction cost economicsframeworks,which ignore cultural differences. Few studies have analyzed inter-organizational cooperation in Mexico, a less-developed country (LDC) with a cultural and industrial environment differentfromthe U.S. This study is concerned with the influence of interorganizational trust, individualism and collectivism (indcol), and the superordinate goal ofjust-in-time/total quality management (JIT/TQM) on inter-organizational cooperation.

A Statistical Investigation of the Phenomena of Absolute Tempo as Described by Hallock, Mursell and Others

A Statistical Investigation of the Phenomena of Absolute Tempo as Described by Hallock, Mursell and Others

Date: August 1946
Creator: Glass, Barbara Jean
Description: The problem of absolute or positive pitch has been studied by a considerable number of researchers. This cannot be said, however, for the problem of the element of tempo, or the normal speed of the true beat in music. The reason for this probably lies in the fact that absolute pitch can be measured quite accurately, for it is dependent upon the anatomy and physiology of the ear. On the other hand, a means whereby the innate pulse in music can be externalized so as to be capable of exact expression and measure in number, presents a challenge to those interested in further investigation of this phenomenon.

Differences in Performance Between Minimally Brain-Injured and Normal Children as Measured by the "Birch-Belmont Auditory-Visual Integration Test"

Differences in Performance Between Minimally Brain-Injured and Normal Children as Measured by the "Birch-Belmont Auditory-Visual Integration Test"

Date: December 1970
Creator: Glass, Daniel J.
Description: The problem with which this study was concerned involved the identification of minimally brain-injured children. The performance on the "Birch-Belmont Auditory-Visual Integration Test" by twenty-five minimally brain-injured students was compared to the performance of twenty-five non-brain-injured children. It was found that when ages and I.Q. scores were not significantly different, and when sexes were approximately proportionate, the M.B.I. children scored significantly lower than did the non-brain-injured children. While it was indicated that the minimally brain-injured children perform less adequately on auditory-visual integration, no comparison of intrasensory and intersensory functioning was made. It was suggested that the test not be employed for sole determination of minimal brain injury, but that it may be used as a screening device quite appropriately.

Parents as Therapeutic Agents: A Study of the Effect of Filial Therapy

Parents as Therapeutic Agents: A Study of the Effect of Filial Therapy

Date: May 1986
Creator: Glass, Nancy, 1949
Description: The problem with which this investigation was concerned was that of the use of parents as therapeutic agents. The purpose of this study was twofold. The first was to determine the effect of filial therapy on parental acceptance, self-esteem, parent-child relationship, and family environment. A second was to analyze the results and make recommendations concerning the effectiveness of filial therapy as a treatment modality for parents and their children. The experimental design of the study was a nonrandomized, pretest-posttest, control group design.The sample (N=47) consisted of the experimental group (parents N=15, children N=9) who received filial therapy and the control group (parents N=12, children N=ll) who did not. The treatment included ten, two hour weekly parent training sessions. During these sessions the parents were taught the principles of client-centered play therapy and were instructed to conduct weekly one-half hour play sessions at home with their own children. Based on the findings of this study, the following conclusions were drawn: 1) Filial therapy does significantly increase the parents' feeling of unconditional love for their children and 2) Filial therapy does significantly increase the parents' perception of expressed conflict in their family. In addition to the statistically significant results, there were some ...

Blood and Earth: Indivisible Territory and Terrorist Group Longevity

Blood and Earth: Indivisible Territory and Terrorist Group Longevity

Date: May 2013
Creator: Glass, Richard A.
Description: The study of terrorism has been both broad in scope and varied in approach. Little work has been done, however, on the territorial aspects of terrorist groups. Most terrorist groups are revolutionary to one degree or another, seeking the control of a piece of territory; but for the supportive population of a terrorist group, how important is the issue of territory? Are the intangible qualities of territory more salient to a given population than other factors? Are territorially based terrorist groups more durable than their ideologically or religiously motivated cohorts? This paper aims to propose the validity of the territorial argument for the study of political terrorism.

Responding to Child Sexual Abuse: Exploring the Case Files of Children Under the Age of 6 Admitted to a Children’s Advocacy Center for Evaluation

Date: August 2011
Creator: Glassner, Steven
Description: Research suggests that roughly 25% of women and 10% of men within the United States were sexually abused at some point during childhood. With such high rates of victimization affecting society, the current study explores a population of children under the age of 6 who were suspected of being sexually victimized and thus admitted to a children’s advocacy center (CAC) for evaluation. This investigation contributes to the literature concerning child sexual abuse (CSA) by exploring the characteristics of these alleged victims, the characteristics of their suspected offenders, the alleged victim’s familial demographics characteristics, and by looking at the data pertaining to the incarceration rates of the suspected offenders identified within the sample.

A Study of Four-Mallet Grips Used in Playing Keyboard Percussion Instruments

A Study of Four-Mallet Grips Used in Playing Keyboard Percussion Instruments

Date: August 1971
Creator: Glassock, Lynn
Description: The purpose of this study was to evaluate the efficiency of three common grips used in four-mallet playing. The three grips were referred to as (a) the Musser grip, (b) the cross stick grip No. 1, and (c) the cross stick grip No. 2. A thorough description (including illustrations) was given for each grip. The evaluation of efficiency was made through research testing, which was conducted by the author. Forty individuals participated in the research testing. Four tests were conducted, and each test had ten participants. The individuals who participated in Tests I, II and III had no previous four-mallet experience. The individuals who participated in Test IV had previous four-mallet experience. The evaluation of the efficiency covered by the four tests was limited to (a) horizontal movement of the outside mallet(s), (b) horizontal movement of the inside mallet(s), and (c) horizontal movement of the hand (s). According to Tests I, II and III, the majority of beginning four-mallet players will find the cross stick grip No. 2 the easiest and most efficient (as far as the three movements which were tested are concerned) of the three grips. However, some individuals (a much smaller percentage) will prefer either the Musser ...

Establishing a Special Interest City Magazine: D, the Magazine of Dallas

Date: December 1975
Creator: Glaves, Robert F.
Description: The problem of this study was to determine how, and to what degree, a representative contemporary special interest magazine projected editorial, advertising, circulation, and financial obligations prior to publication and during its infancy. In essence, how did a representative nonsubsidized city magazine identify a marketable audience, resolve advertising and circulation policies, and meet financial obligations? Specifically, this study explored--in six chapters--the mechanics of pre- and post-publication planning at D, The Magazine of Dallas, which began publication in October, 1974. This study determined that twelve common denominators are essential, but are not necessarily a guarantee, for the success of a planned or newly introduced nonsubsidized special interest magazine.

The Rhetoric of Androgyny: Gender and Boundaries in Le Guin's The Left Hand of Darkness

The Rhetoric of Androgyny: Gender and Boundaries in Le Guin's The Left Hand of Darkness

Date: August 1996
Creator: Gleason, Benjamin P. (Benjamin Patrick)
Description: The androgyny of the Gethenians in The Left Hand of Darkness is a vehicle for Ursula Le Guin's rhetoric concerning gender roles. Le Guin attempts to make the reader identify with an ideal form of androgyny, through which she argues that many of the problems of human existence, from rape and war to dualistic thought and sexism, are products of gender roles and would be absent in an androgynous world. The novel also links barriers of separation and Othering with masculine thought, and deconstructs these separative boundaries of opposition, while promoting connective borders which acknowledge difference without creating opposition. The novel thus criticizes gendered thought processes and social roles, because they lead to opposition and separation.
