Jul 2, 2020 at 14:36 comment added Simon Alford I see. The first ๐‘‘๐ฟ/๐‘‘๐ณ($t_1$) comes from the paper. I'm not sure where โˆ’๐‘‘๐ฟ/๐‘‘๐ญ($t_1$) comes fromโ€”this term isn't mentioned in the paper. It looks like this term is needed for using the gradient. I'm guessing there's something going on with the chain rule here.
Jul 2, 2020 at 11:52 comment added secondrate Hi, thanks for the comment. Actually, I don't understand how they came up with the adjustments, i.e. why is it $\frac{dL}{d\mathbf{z}(t_1)}$ and why is it $-\frac{dL}{d\mathbf{t}(t_1)}$? I'm wondering if someone can demonstrate mathematically how to procedurally compute the gradient of the loss on the intervals $[t_1,t_2]$ and $[t_0,t_1]$. This would then explain to me why it has to be done.
