We use the notion of the logarithm of the derivative operator to describeW∞ type algebras as central extensions of the algebra of differential operators. We also provide closed formulae for the ...

Abstract: The Laplace-domain waveform inversion is a full-waveform inversion method that recovers large-scale subsurface models. The inversion updates subsurface model parameters to minimize the ...

Abstract: Activation functions playa key role in providing remarkable performance in deep neural networks, and the rectified linear unit (ReLU) is one of the most widely used activation functions.

Many of the irrational and transcendental functions are multiply defined in the complex domain; for example, there are in general an infinite number of complex values for the logarithm function. In ...
