Deep Learning: Foundations and Concepts

finished 2.1.2. The sum and product rules

not a pleasure to read, the math isn’t that hard, but needs enough context which’s not obvious in the textbook. since it’s been a long time since I picked up the math tool, I’m not used to them yet. and also, I’m not really good at English in such scenerio. it take extra effort to follow.

marginalization:

p(X=xi)=∑j=1Mp(X=xi, Y=yj)(2.4)p(X = x_i) = \sum_{j=1}^{M} p(X = x_i,\, Y = y_j) \tag{2.4}
