#StackBounty: #entropy #information-gain Does this middle variable have any information gain?

Bounty: 50

Let’s say that I have 2 variables: A (as the input) and C (as the output)
So it’s A -> C
There’s also another variable B, and
corr(A, B) > corr(A, C)
corr(C, B) > corr(A, C)

Would A -> B -> C get better performance with the existing model?
In other words, does this B have any information gain?
