WebA graphical model formalizes the structure of the dependencies between random variables. It also drastically reduces the number of degrees of freedom in our probability distributions, making it possible for us to reason about the data we can collect and make inferences about the things we can’t measure directly. Figure 1: Example Graphical Model. Webother variables. This is what graphical models let us do. 21.1 Conditional Independence and Factor Models The easiest way into this may be to start with the diagrams we drew for factor anal-ysis. There, we had observables and we had factors, and each observable depended on, or loaded on, some of the factors. We drew a diagram where we had nodes,

You can view a deep neural network as a graphical model, but here, the CPDs are not probabilistic but are deterministic. Consider for example that the input to a neuron is x → and the output of the neuron is y. In the CPD for this neuron we have, p ( x →, y) = 1, and p ( x →, y ^) = 0 for y ^ ≠ y.
