Book excerpt: With the growth in size and complexity of data, methods exploiting low-dimensional structure, as well as distributed methods, have been playing an ever important role in machine learning. These approaches offer a natural choice to alleviate the computational burden, albeit typically at a statistical trade-off. In this thesis, we show that a careful utilization of structure of a problem, or bottlenecks of a distributed system, can also provide a statistical advantage in such settings. We do this from the purview of the following three problems: 1. Learning Graphical models with a few hubs: Graphical models are a popular tool to represent multivariate distributions. The task of learning a graphical model entails estimating the graph of conditional dependencies between variables. Existing approaches to learn graphical models require a number of samples polynomial in the maximum degree of the true graph, which can be large even if there are a few high-degree nodes. In this part of the thesis, we propose an estimator that detects and then ignores high degree nodes. Consequently, we show that such an estimator has a lower sample complexity requirement for learning the overall graph when the true graph has a few high-degree nodes or "hubs" for e.g. scale-free graphs. 2. Kernel Ridge Regression via partitioning: Kernel methods find wide and varied applicability in machine learning. However, solving the Kernel Ridge Regression (KRR) optimization requires computation that is cubic in the number of samples. In this work, we consider a divide-and-conquer approach to solve the KRR problem. The division step involves splitting the samples based on a partitioning of the input space, and the conquering step is to simply use the local KRR estimate in each partition. We show that this can not only lower the computational requirements of solving the KRR problem, but also lead to improved accuracy over both a single KRR estimate, and estimates based on random data partitioning. 3. Stragglers in Distributed Synchronous Gradient Descent: Synchronous methods in machine learning have many desirable properties, but they are only as fast as the slowest machine in a distributed system. The straggler/slow machine problem is a critical bottleneck for such methods. In this part of our work, we propose a novel framework based on Coding Theory for mitigating stragglers in Distributed Synchronous Gradient Descent (and its variants). Our approach views stragglers as errors/erasures. By carefully replicating data blocks and coding across gradients, we show how this can provide tolerance to failures and stragglers without incurring any communication overheads.

Download or read book Modernizing Learning written by JJ Vogel-Walcutt and published by Government Printing Office. This book was released on 2019-06-27 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modernizing Learning: Building the Future Learning Ecosystem is an implementation blueprint for connecting learning experiences across time and space. This co-created plan represents an advancement of how and where learning will occur in the future. Extensive learning and technological research has been conducted across the myriad disciplines and communities needed to develop this holistic maturation of the learning continuum. These advancements have created the opportunity for formal and informal learning experiences to be accessible anywhere, anytime, and to be personalized to individual needs. However, for full implementation and maximal benefits for learners of all ages and within all communities to be achieved, it is necessary to centralize and coordinate the required connections across technology, learning science, and the greater supporting structures. Accordingly, the ADL Initiative has taken the lead in this coordination process, connecting Government, Military, Academia, Industry, and K-12 teachers, instructors, technologists, researchers, and implementers to create and execute a coordinated transition process. Input was included from stakeholders, communities, and supporting entities which will be involved in this advancement of the life-long learning ecosystem.
Download or read book Distributed Learning Systems with First order Methods written by Ji Liu and published by Now Publishers. This book was released on 2020-06-17 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scalable and efficient distributed learning is one of the main driving forces behind the recent rapid advancement of machine learning and artificial intelligence. One prominent feature of this development is that recent progress has been made by researchers in two communities: (1) the system community such as database, data management, and distributed systems, and (2) the machine learning and mathematical optimization community. The interaction and knowledge sharing between these two communities has led to the rapid development of new distributed learning systems and theory. This monograph provides a brief introduction to three distributed learning techniques that have recently been developed: lossy communication compression, asynchronous communication, and decentralized communication. These have significant impact on the work in both the system and machine learning and mathematical optimization communities but to fully realize the potential, it is essential they understand the whole picture. This monograph provides the bridge between the two communities. The simplified introduction to the essential aspects of each community enables researchers to gain insights into the factors influencing both. The monograph provides students and researchers the groundwork for developing faster and better research results in this dynamic area of research.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to compare the differential effects of the organizational structure of learning as influenced by a year-round calendar (distributed learning) vs. a traditional calendar (massed learning) on student attendance and student achievement. Research that dates back to 1885 and the work of Hermann Ebbinghaus was revisited in order to make application of his findings regarding memory and retention as related to an investigation into the effect of school calendar and academic learning time upon student achievement. This quantitative causal-comparative research study included 28 elementary schools operating under a year-round calendar. Student achievement data were collected for third-, fourth-, and fifth- grades using the campus average reading and mathematics scores from the Texas Assessments of Knowledge and Skills. Student attendance rates for all the campuses were collected from the Academic Excellence Indicator System. The student achievement data and the overall campus student attendance rate were compared to 28 identified traditional calendar schools, selected from a comparable campus group, as assigned by the Texas Education Agency (TEA). Findings revealed one area of academic difference for fifth grade economically disadvantaged students in mathematics and a difference in attendance. Both differences where found in favor of the traditional calendar; however the general conclusion was that the year-round school calendar and the traditional school calendar do not have dramatically different outcomes and the scheduling of the Texas Assessment of Knowledge and Skills (TAKS) may favor the traditional calendar.

Available in PDF, EPUB and Kindle. Book excerpt: A vision of the future of education in which the classroom experience is distributed across space and time without compromising learning. What if there were a model for learning in which the classroom experience was distributed across space and time--and students could still have the benefits of the traditional classroom, even if they can't be present physically or learn synchronously? In this book, two experts in online learning envision a future in which education from kindergarten through graduate school need not be tethered to a single physical classroom. The distributed classroom would neither sacrifice students' social learning experience nor require massive development resources. It goes beyond hybrid learning, so ubiquitous during the COVID-19 pandemic, and MOOCs, so trendy a few years ago, to reimagine the classroom itself. David Joyner and Charles Isbell, both of Georgia Tech, explain how recent developments, including distance learning and learning management systems, have paved the way for the distributed classroom. They propose that we dispense with the dichotomy between online and traditional education, and the assumption that online learning is necessarily inferior. They describe the distributed classroom's various delivery modes for in-person students, remote synchronous students, and remote asynchronous students; the goal would be a symmetry of experiences, with both students and teachers able to move from one mode to another. With The Distributed Classroom, Joyner and Isbell offer an optimistic, learner-centric view of the future of education, in which every person on earth is turned into a potential learner as barriers of cost, geography, and synchronicity disappear.

This book was released on 2012-02-07 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world of education is being radically altered with the change being driven by technology, openness, and unprecedented access to knowledge. Older correspondence-style methods of instructional delivery are passé and “classroom adapted to the web” approaches to learning are often ineffective and do little to harness the transformational potential of technology. E-Learning scenarios, mobile technologies, communication and information access, and personal learning environments are becoming mainstream and, as a result, control of the learning process is shifting away from institutions and into the hands of learners. This volumes promotes a forward-thinking agenda for research and scholarship that highlights new ideas, deep insights, and novel approaches to “unconstrained” learning.

Download or read book Transactional Distance and Adaptive Learning written by Farhad Saba and published by Routledge. This book was released on 2017-10-16 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transactional Distance and Adaptive Learning takes a fresh look at one of the pioneering educational theories that accommodates the impact of information and communications technologies in learning. The theory of transactional distance (TTD) provides a distinct analytical and planning foundation for educators to conduct an overarching inquiry into transitioning from mass instructional and management systems in higher education to dynamic and transformational futures that focus on each individual learner. Based on the TTD, this pragmatic approach offers instructors, administrators, students, and other stakeholders a comprehensive planning method to assess the current state of their instructional, learning, and management practices and to develop alternative models to prescribe future improvements in their institution. This complex, self-organized, and adaptive method includes current and emergent properties of: hardware, software, and telecommunications systems that allow faculty, students, and administrators to communicate; instructional and curriculum systems that provide teaching and learning environments for faculty and students; and management, societal, and global systems that influence how institutions are supported, funded, and managed.

Download or read book Using Modular Architectures Within Distributed Learning Environments written by Paul Cholmsky and published by . This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In addition to reducing costs associated with system development, modular architectures provide large-scale distributed learning environments with the flexibility required to meet the diverse needs of a global audience. Comprehensive standards for implementing such architectures are now being developed by several organizations. In order to take full advantage of these standards, instructional content design and development processes may need to be modified. The first part of the thesis investigates the foundations of computer-based learning environments, and the historical development of instructional design methodologies in this domain. Specific emphasis is placed on the human factors involved in formalizing a design process, and how the concept of systematicity in design may evolve in the context of complex learning systems. Modular architectures are presented as a technique for ameliorating the complexity of design in this domain. The second part of the thesis examines and critiques a recently-proposed standardized data model for distributed assessment systems. The concept of a distributed computer-based assessment system is first briefly defined. This is followed by an identification of the drivers underlying the need for a standardized data model, and a discussion of what constitutes a suitable methodology for evaluating such a standard in advance of its field implementation. After outlining the structural and functional aspects of the candidate standard, the IMS Question & Test Interoperability Information Model (Smythe & Shephed, 2000), the merits and failings of the standard are discussed, and a set of recommendations for the evolution of the standard is made.
