Whiteboard from today's meeting on Bayesian ML:

Cox:  P(A, B) = P(A|B)P(B) = P(B|A)P(A)
=>
P(A|B) = [P(B|A)P(A)] / P(B) (Bayes)
The ML model needs to be a generative model - statistically model that generate data
Example - a mixture of normal distribution.   Two normal distributions.  You choose which one you use in probability 1/2 and then you use to generate data.   
(n+1)! = (n+1)(n)!

We revised Bayesian thinking and it's relation to ML.    https://drive.google.com/file/d/1CHxUPqtkyNWCklT7sgOC6I7YzAj29R-s/view?usp=sharing
