Dear All,
I am a starter to machine learning and i am currently confused about the following problem:
what is the result of P(X|Y)P(Y|Z)?
In my book, it is written to be P(X|Z). But I don't think it is correct since
P(X|Z)= P(X|Y,Z)P(Y|Z)
But clearly P(X|Y)=/= P(X|Y,Z)
Assuming all Events are not independent.
I have simplified the problem in the above equation. The true equation is
p(w|x,t,α,β)proportional to p(t|x,w,β)p(w|α) from pattern recognition and machine learning written by christopher m. bishop.
Any helps and ideas will be very appreciated.
