figure out how logP is calculated.
Anyone else who can help out here?
Isn't this just log(P) where P is the number of cores? The version of
the paper I have says log(P) not logP, so maybe there is a typo?
From earlier in 4.1:
"We assume that the dimension of the inputs is n (i.e., x
∈R
n
), that we have m
training examples, and that there are P cores"
