这有什么样的噪音？

Question

会产生什么样的噪音numpy.random.random((NX,NY))？白噪声？如果它有所不同,我有时会产生3D或1D噪音(参数是(NX,NY,NZ)或(N,)).

Answer 1

>>> help(numpy.random.random)
Help on built-in function random_sample:

random_sample(...)
    random_sample(size=None)

    Return random floats in the half-open interval [0.0, 1.0).

    Results are from the "continuous uniform" distribution over the
    stated interval.  To sample :math:`Unif[a, b), b > a` multiply
    the output of `random_sample` by `(b-a)` and add `a`::

      (b - a) * random_sample() + a
    ...

正如帮助所说,numpy.random.random()提供"连续统一"分布.

用于"高斯/白噪声"分布使用numpy.random.normal().
