To solve this, I’ll compute the Softmax probabilities for the given scores Z1, Z2, Z3.
First, calculate the exponentials: exp(Z1) = exp(-1) ≈ 0.3678794412, exp(Z2) = exp(1) ≈ 2.718281828, exp(Z3) = exp(2) ≈ 7.389056099.
Next, sum these exponentials to obtain the normalization constant: S = 0.3678794412 + 2.718281828 + 7.3890......Login to view full explanation登录即可查看完整答案
