A review of discrete solutions of poisson, laplace, and wave equations
Sevgi, Levent (Dogus Author)One- and two-dimensional discrete solutions of Poisson, Laplace, and wave equations are given in this tutorial. The terms wave propagation and numerical propagation are discussed. Simple MATLAB scripts are also supplied.IEEE Antennas and Propagation Societ
On Quadratic Penalties in Elastic Weight Consolidation
Elastic weight consolidation (EWC, Kirkpatrick et al, 2017) is a novel
algorithm designed to safeguard against catastrophic forgetting in neural
networks. EWC can be seen as an approximation to Laplace propagation (Eskin et
al, 2004), and this view is consistent with the motivation given by Kirkpatrick
et al (2017). In this note, I present an extended derivation that covers the
case when there are more than two tasks. I show that the quadratic penalties in
EWC are inconsistent with this derivation and might lead to double-counting
data from earlier tasks
