I am a engineer working in an Internet Corporation. I am reading the paper
"Bayesian Factorization Machines".And i do not understand why the
distribution of theta can be described as the formulas in section 2.3.
Why is the theta distributed as Gaussian? And why could the mean and
variance of theta can calculated as the formula?
Is there any reference or book content can help me figure this out?

What's more, Is there any reference to help me understand the MCMC algorithm related to libFM?
Many thanks!
