Title: Roots of the identity operator and proximal mappings: (classical and phantom) cycles and gap vectors
Speaker: Shawn Wang (The University of British Columbia)
Date and Time: Wed Mar 23 2022, 11:00 AEST (Register here for remote connection via Zoom)
Abstract:
Recently, Simons provided a lemma for a support function of a closed convex set in a general Hilbert space and used it to prove the geometry conjecture on cycles of projections. We extend Simons’s lemma to closed convex functions, show its connections to Attouch-Théra duality, and use it to characterize (classical and phantom) cycles and gap vectors of proximal mappings. Joint work with H. Bauschke
The School of Mathematics at Monash is advertising a continuing B/C position in
numerical and computational mathematics.
The application deadline is Sunday 24 April 11:55pm Melbourne time.
The group of numerical and computational mathematics at Monash has recently grown a lot and covers many aspects in this field: numerical analysis, high performance computing, optimisation and OR, inverse problems, uncertainty quantification, etc. The School of Mathematics itself is a vibrant department with strong research in many aspects of applied mathematics, pure mathematics and probability/statistics.

Title: Generalized Gearhart-Koshy acceleration for the Kaczmarz method
Speaker: Janosch Rieger (Monash University)
Date and Time: Wed Mar 16 2022, 17:00 AEST (Register here for remote connection via Zoom)
Abstract:
The Kaczmarz method is an iterative numerical method for solving large and sparse rectangular systems of linear equations. Gearhart and Koshy have developed an acceleration technique for the Kaczmarz method for homogeneous linear systems that minimises the distance to the desired solution in the direction of a full Kaczmarz step. Matthew Tam has recently generalised this acceleration technique to inhomogeneous linear systems.
In this talk, I will develop this technique into an acceleration scheme that minimises the Euclidean norm error over an affine subspace spanned by a number of previous iterates and one additional cycle of the Kaczmarz method. The key challenge is to find a formulation in which all parameters of the least-squares problem defining the unique minimizer are known, and to solve this problem efficiently.
The 2022 AMSI ACE network Optimisation course will launch on February 28, 2022. This year’s theme is “Theory and Methods of Modern Optimisation,” and the instructors are Prof. Andrew Eberhard (RMIT University) and Dr. Scott B. Lindstrom (Curtin Centre for Optimisation and Decision Science). Details and pre-enrolment quiz are currently available on the AMSI website. Please share with any students who might benefit from this opportunity.
Dear MoCaO members. The computational chair, Stephen Roberts has decided to step down from the position of co-chair (computation) due to personal circumstances. The executive of MoCaO has unanimously agreed to appoint the runner up for the co-chair (computation) position in the 2020-2021 executive elections, Quoc Thong Le Gia, as co-chair (computational) to fill this position for the remainder of this executives term. We thank Thong for agreeing to take on this important role.
Congratulations, Thong!
