Ind Probablist Graphical Models

Probablistic graphical models is turning out to be quite interesting as well. It's not an easy way to describe it, and anybody who's not very technical or math oriented would be like, why are you taking this for funum? But the idea is, like, how do you present like dependencies so that their basic example of a grade in a class can be drawn. And then you assign weights to the probabilities of various conditioning conditions happening. I assume it will get even more complex as it goes by basically having these models be created by just looking at the data  that take data and generate the models.
