  • monaural music source separation nonnegativity sparseness and shift invariance
    International Conference on Independent Component Analysis and Signal Separation, 2006
    Co-Authors: Seungjin Choi
    Abstract:

    In this paper we present a method for polyphonic music source separation from their monaural mixture, where the Underlying Assumption is that the harmonic structure of a musical instrument remains roughly the same even if it is played at various pitches and is recorded in various mixing environments. We incorporate with nonnegativity, shift-invariance, and sparseness to select representative spectral basis vectors that are used to restore music sources from their monaural mixture. Experimental results with monaural instantaneous mixture of voice/cello and monaural convolutive mixture of saxophone/viola, are shown to confirm the validity of our proposed method.

  • Learning Science: Some Insights from Cognitive Science
    Science & Education, 2000
    Co-Authors: P. S. C. Matthews
    Abstract:

    Theories of teaching and learning, including those associated with constructivism, often make no overt reference to an Underlying Assumption that they make; that is, human cognition depends on domain-free, general-purpose processing by the brain. This Assumption is shown to be incompatible with evidence from studies of children's early learning. Rather, cognition is modular in nature, and often domain-specific. Recognition of modularity requires a re-evaluation of some aspects of current accounts of learning science. Especially, children's ideas in science are sometimes triggered rather than learned. It is in the nature of triggered conceptual structures that they are not necessarily expressible in language, and that they may not be susceptible to change by later learning.

  • Learning theory: The pandemic research challenge
    Journal of Management Studies, 2020
    Co-Authors: Henrich R. Greve
    Abstract:

    Abstract Organizational learning theory examines how organizations change routine behaviors as a function of their goals and experience (Levitt and March, 1988) Research built on learning theory has assembled much evidence on how organizations adapt to their environments (e g , Gavetti, Greve, Levinthal and Ocasio, 2012) Learning acts both as an Underlying Assumption in other theories and as a theory on its own, and is used in organizational theory, strategy, and entrepreneurship This foundational role means that a reassessment of learning theory is consequential for the wider field of management, not just for scholars specialized in learning theory

  • Evaluating groupware support for software engineering students
    Computer Science Education, 2001
    Co-Authors: Sarah Drummond, Cornelia Boldyreff, Magnus Ramage
    Abstract:

    Software engineering tasks, during both development and maintenance, typically involve teamwork using computers. Team members rarely work on isolated computers. An Underlying Assumption of our research is that software engineering teams will work more effectively if adequately supported by network-based groupware technology. Experience of working with groupware and evaluating groupware systems will also give software engineering students a direct appreciation of the requirements of engineering such systems.

  • CSEE&T - The development and trial of SEGWorld: a virtual environment for software engineering student group work
    Thirteenth Conference on Software Engineering Education and Training, 1
    Co-Authors: Sarah Drummond, Cornelia Boldyreff
    Abstract:

    Software engineering tasks, during both development and maintenance, typically involve teamwork using computers. Team members rarely work on isolated computers. An Underlying Assumption of our research is that software engineering teams will work more effectively if adequately supported by network-based groupware technology and project management tools. This research is investigating the provision of such network-based support for software engineering teams. The immediate objective is to provide network-based support, specifically for students working on software engineering group (SEG) projects in the Department of Computer Science at Durham. The long term objectives are to develop more flexible support for group working among computer science students and their staff supervisors for project work and tutorials in general. This paper reports on our recent results and assesses how far we have been successful in achieving our immediate objective.
