Predicted y_batch .sum

WebJul 10, 2024 · Where $\bf{\hat{y}}$ is the predicted probability vector (Softmax output), and $\bf{y}$ is the ground-truth vector( e.g. one-hot). The reason we use natural log is because it is easy to differentiate (ref. calculating gradients) and the reason we do not take log of ground truth vector is because it contains a lot of 0's which simplify the summation.
