| বিবরন: | Often we encounter high dimensional differential equations. A clever representation of a generalized solution could be procured in certain cases using Green functions. We show how this representation could be achieved and via a clever Fourier mode decomposition for the particular disc case resulting in a highly correlated set of functions that transforming into a discrete representation – via a classical second order finite difference approximation – can be ultimately represented as a linear equation for matrices embedding all boundary conditions in the structure of such objects. The resulting problem could be solved using stochastic gradient descent with an additional on-the-fly optimization reducing required computation resources substantially. |
