Yes No Yes If X is normally distributed with mean μ and standard deviation σ, then log(X) is not normally distributed. The logarithm function is nonlinear and can distort the distribution of the original variable. For log(X) to be normal, X must be lognormal. Since learning_rate is normal distribution not lognormal, second one should be no.

Yes, Yes, Yes. if the distribution is normal, taking a log of the same distribution will resemble normal distribution.
