    Learning Optimization-inspired Image Propagation with Control Mechanisms and Architecture Augmentations for Low-level Vision

    Full text link
    In recent years, building deep learning models from optimization perspectives has becoming a promising direction for solving low-level vision problems. The main idea of most existing approaches is to straightforwardly combine numerical iterations with manually designed network architectures to generate image propagations for specific kinds of optimization models. However, these heuristic learning models often lack mechanisms to control the propagation and rely on architecture engineering heavily. To mitigate the above issues, this paper proposes a unified optimization-inspired deep image propagation framework to aggregate Generative, Discriminative and Corrective (GDC for short) principles for a variety of low-level vision tasks. Specifically, we first formulate low-level vision tasks using a generic optimization objective and construct our fundamental propagative modules from three different viewpoints, i.e., the solution could be obtained/learned 1) in generative manner; 2) based on discriminative metric, and 3) with domain knowledge correction. By designing control mechanisms to guide image propagations, we then obtain convergence guarantees of GDC for both fully- and partially-defined optimization formulations. Furthermore, we introduce two architecture augmentation strategies (i.e., normalization and automatic search) to respectively enhance the propagation stability and task/data-adaption ability. Extensive experiments on different low-level vision applications demonstrate the effectiveness and flexibility of GDC.Comment: 15 page

    Cameron cites the infusion of collaborative values and restructuring of relationships as a primary reason for the successful clean up and closure of Rocky Flats, one of U.S.’s most hazardous and controversial toxic dumps. Success was contingent upon mutual trust and respect of and between traditionally adversarial groups by adopting a mutual proactive, sharing orientation and empathetic attitudes. The true leaders in this venture shifted from a profit-first stance to changing organizational culture, ensuring that individuals (especially leaders and influencers) pursued an abundance-based vision

    A New Era of Education Reform: Preparing All Students for Success in College, Career and Life

    Get PDF
    As society changes, the knowledge and skills required for citizens to navigate the complexities of life and work must also change. As a result, some argue that schools must provide students with a broader set of skills that will enable them to thrive in our increasingly diverse, rapidly evolving and globally-connected world. The intent is not to replace the traditional academic disciplines but to infuse them with knowledge and skills that will better prepare students for success in the 21st century -- often referred to as "21st century skills." While others maintain that as long as a portion of the student population is not mastering basic reading, writing and mathematics skills, schools must continue to focus exclusively on the traditional core academic disciplines. In order to inform the debate about the rationale for and relevance of 21st century skills in Massachusetts' public schools, the Rennie Center for Education Research & Policy conducted a survey of superintendents, charter school leaders and principals statewide to gauge the extent to which school and district leaders support the integration of 21st century skills into public education. The goal of the survey was to provide a better understanding of Massachusetts' public school and district leaders' priorities for improving student learning, including their views on 21st century skills. The survey was followed by interviews with a small sample of administrators and educators in districts and schools where the integration of 21st century skills is a priority, in order to better understand district, school and teacher approaches for infusing 21st century skills into teaching and learning.The report describes the background and context for the study, the study methodology, and key findings from the statewide survey and interviews in a sample of schools and districts. The final section of the report puts forth considerations for policymakers and K-12 school and district leaders. Case studies of two public school districts, Reading Public Schools and Brockton Public Schools are included in Appendix B. The case studies offer two different approaches to integrating 21st century skills district-wide. The case study of Reading Public Schools illustrates a district-led approach. The case study of Brockton Public Schools is an example of how one school has spurred a district to focus on 21st century skills.The study gives voice to key education stakeholders who have not been part of the public debate about 21st century skills and provides clarity about what teaching and learning in classrooms that incorporate 21st century skills looks like. While opponents of 21st century skills argue that districts where most students have not yet mastered reading, writing and mathematics skills, should focus exclusively on core academic content, the study revealed that most school and district leaders believe all public schools in Massachusetts should be required to integrate 21st century skills into learning, including schools where students are lacking adequate basic skills. Interviews with superintendents who prioritize integration of 21st century skills revealed that input from a range of stakeholders led their district to expand their mission and vision for student learning to include 21st century skills and rather than adopt a pre-packaged set of skills, the focus in these districts is on particular skills and competencies that ?t the needs of their student body. While most schools and districts have not developed measurable goals for student mastery of 21st century skills, interviews with a small sample of administrators and educators revealed that 21st century skills are assessed at the classroom level, and most administrators view school- and district-wide assessment as a future step in the process of fully integrating 21st century skills. The endings also suggest that administrators believe that, to date, state policymakers have not adequately supported the teaching and learning of 21st century skills.This report was released at a public event on October 7th, 2010.

    Integrating mobile robotics and vision with undergraduate computer science

    Get PDF
    This paper describes the integration of robotics education into an undergraduate Computer Science curriculum. The proposed approach delivers mobile robotics as well as covering the closely related field of Computer Vision, and is directly linked to the research conducted at the authors’ institution. The paper describes the most relevant details of the module content and assessment strategy, paying particular attention to the practical sessions using Rovio mobile robots. The specific choices are discussed that were made with regard to the mobile platform, software libraries and lab environment. The paper also presents a detailed qualitative and quantitative analysis of student results, including the correlation between student engagement and performance, and discusses the outcomes of this experience
