ITERATIVE PROJECTION AND REFLECTION METHODS: THEORY AND PRACTICE

A Reflection on Research, Theory, Evidence-based Practice, and Quality Improvement

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

Norm Convergence of Realistic Projection and Reflection Methods

The (2-set) convex feasibility problem asks for a point contained within the intersection of two closed convex sets of a Hilbert space. Projection and reflection methods represent a class of algorithmic schemes which are commonly used to solve this problem. Some notable projection and reflection methods include the method of alternating projections, the Douglas–Rachford method, the cyclic Dougl...

Iterative Projection Methods for Structured Sparsity Regularization

In this paper we propose a general framework to characterize and solve the optimization problems underlying a large class of sparsity based regularization algorithms. More precisely, we study the minimization of learning functionals that are sums of a differentiable data term and a convex non differentiable penalty. These latter penalties have recently become popular in machine learning since t...

Iterative Combinatorial Auctions: Theory and Practice

Combinatorial auctions, which allow agents to bid directly for bundles of resources, are necessary for optimal auction-based solutions to resource allocation problems with agents that have non-additive values for resources, such as distributed scheduling and task assignment problems. We introduce iBundle, the first iterative combinatorial auction that is optimal for a reasonable agent bidding s...
