Gaussian functions arise by composing the exponential function with a concave quadratic function: (Note: in , not to be confused with ) The Gaussian functions are thus those functions whose logarithm is a concave quadratic function. WebGaussian processes regression is prone to numerical problems as we have to inverse ill-conditioned covariance matrix. To make this problem less severe, you should standardize your data. Some packages do this job for you, for example GPR in sklearn has an option normalize for normalization of inputs, while not outputs; see this .

Since we may need to deal with integrals of the type you will require that the wave functions ψ(x, 0) go to zero rapidly as x→ ±∞ often faster than any power of x. We shall also require that the wave functions ψ(x, t) be continuous in x. can sharks make noise

In mathematics and numerical analysis, the Ricker wavelet [1] is the negative normalized second derivative of a Gaussian function, i.e., up to scale and normalization, the second Hermite function. It is a special case of the family of continuous wavelets ( wavelets used in a continuous wavelet transform) known as Hermitian wavelets.

Web$\begingroup$ @JohnDemetriou May not be the cleanest solution, but you can scale the normalized values to do that. If you want for example range of 0-100, you just multiply each number by 100. If you want range that is not beginning with 0, like 10-100, you would do it by scaling by the MAX-MIN and then to the values you get from that just adding the MIN.
