Here is Dan … Webb21 maj 2024 · We start with our above formulation of the MMI objective and break the log into the smaller terms. Here we have used ∇θlogP(Wr) = 0 since P(Wr) is independent of θ. Now we simplify the second term inside the sum. Here we have used the fact that P( ˆW) is independent of θ so it becomes a constant for the gradient. safety observation ideas
