Question 6

+2 marksOne correct option

Which of the following is incorrect for the reparametrization trick used in a Variational AutoEncoder (VAE)?

  1. A

    This technique is used, since the expected reconstruction error requires estimation by sampling which has very high variance.

  2. B

    It can be applied to any “location-scale” family of distributions where the location (mean) and scale (variance) of the standard version is 0 and 1.

  3. C

    The reparametrization trick is applicable to continuous distributions as well as discrete distributions.

  4. D

    It allows the random variable to be expressed as a different transformation of auxiliary variables which helps the gradient estimation with only one sample
