Title: Preliminary results on: 3D MT Inversion through Evolution of Ellipsoid Functions
Abstract:
For some time genetic algorithms (GAs) have been successfully applied to the problem of 1D and 2D MT inversion. There is, however, a much smaller amount of work on the application of GAs to 3D inversion. This may be partly because traditional GA encodings of models can result in extremely long genomes when used to express 3D models. This talk describes new work that uses genomes that parametrically encode a model as a series of ellipsoidal volumetric functions (metaballs). This compact representation is much more amenable to evolution whilst still providing enough flexibility to express reasonably detailed models. The talk will present some very early results and discuss future directions in the development of the algorithm.

Big thank you to @MartinaPQuinn of @helloalicepr for moderating the discussion, and of course to our panel @NeasaMcG @CormacORafferty and @laoneill111
@CormacORafferty "to cut yourself off from fundamental research means you could miss out on some of the biggest ideas"
@laoneill "it's our job as researchers to keep reminding governments how important basic research is" "For Dev basic research being carried out in Ireland was a badge of pride"
@NeasaMcG Schrödinger's work in causality was not well received by the religious authorities at the time At the same time DIAS did have Catholic priests working on research projects in the early days, so there was not the conflict you might think between science and religion
@laoneill111 Schrödinger was very popular in social circles in Dublin, a bit of a renaissance man
@CormacORafferty Schrödinger was gifted at explaining difficult concepts
@CormacORafferty on how unsuccessful work, in Schrödinger's case, unified field theory, is just as important part of science. And no one has managed to crack it yet! And not forgetting the cat
@laoneill111 how Schrödinger's book inspired scientists to change fields and result in the finding of the double helix.
@NeasaMcG explaining how DIAS came about and how Schrödinger was attracted to Ireland #DIASdiscovers
Panel Discussion getting underway! @laoneill111 @CormacORafferty @NeasaMcG @MartinaPQuinn
