Gaussian.Uniform() RRS feed

  • Question

  • Hi,

    Can anyone help me in understanding "Gaussian.Uniform()" ? Is this something related to uniform distribution also?

    Thanks a lot in advance.

  • In Infer.NET terms, that's a Gaussian with a zero precision.

  • It's an improper distribution - i.e. you the probability density for any real value is 0.0. It is useful in the calculus of message passing which involves products and ratios of distribution functions. Multiplying a Gaussian message by a uniform Gaussian message does not change the original message.
