Hi everyone,

I've a question in sorta of an advanced channel coding. The subject in specific is Marginalize Product of Functions as the title says.

I've this function:

I'm asked to:
1. Evaluate K.
2. Give a graphical representation to f.
3. Apply (step by step) message passing to marginalize with respect to each xi.

The first one I've already did it, and I came up with K=0.73. The second one I think I can do it, so I'm asking for help with 3. How can I start?
