【注意这里有两个kernel,第一个是RKHS里面的kernel K,第二个是heat equation的transition prob,这俩有关但不一样。具体关系在更general的意义下是怎样的?】 其他 RKHS涵盖内容非常广泛。像上文说的Sobolev space是Matern kernel的RKHS。另外,polynomial 也可以组成什么basis之类,和spline有点关系。很多stochastic proces...

The heat equation, Eq. (3.29), is the anisotropic diffusion equation: (3.32)∂P/∂t=∇⋅(cx,y(t)∇Px,y(t)) where ∇⋅ is the divergence operator (which essentially measures how the density within a region changes), with diffusion coefficient cx,y. The diffusion coefficient ...
The type of the evolution equation considered here comes from the study of the heat equation on a class of solvable Lie groups, the so called higher rank NA groups which are, by definition, the semi-direct products of a nilpotent and abelian (with dimension greater than 1) groups (more ...
This covariance function can be derived in a few different ways: as the infinite limit of a radial basis function neural network, as diffusion in the heat equation, as a Gaussian filter in Fourier space or as the composition as a series of linear filters applied to a base function....
The diffusion PDE or heat equation (∂t−Δ1)f(⋅,t)=0 with initial condition f(⋅,0)=fX (1) equilibrates the density fX, thus mitigating the challenges outlined above. Here, ∂t denotes the standard partial derivative with respect to time ∂∂t and Δ1=Tr∘∇12 is...

In the near field, whereby the point source idealization fails, the temperature field is expected to be modulated by the Gaussian distribution. Figure 73 depicts the temperature profile for a Gaussian intensity distribution of the heat source. The solution given in Eq. 3.14 is given for infinite...
