Usually, for a straight-line graph, finding the slope is very easy. One simply divides the "rise" by the "run" - the amount a function goes "up" or "down" over a certain interval. For a curved line, the technique is pretty similar - pick an interval ...

WebMay 1, 2024 · Softmax is essentially a vector function. It takes n inputs and produces and n outputs. The out can be interpreted as a probabilistic output (summing up to 1). A multiway shootout if you will. softmax(a) = [a1 a2 ⋯ aN] → [S1 S2 ⋯ SN] And the actual per-element formula is: softmaxj = eaj ∑Nk = 1eak. WebThe Gradient = 3 3 = 1. So the Gradient is equal to 1. The Gradient = 4 2 = 2. The line is steeper, and so the Gradient is larger. The Gradient = 3 5 = 0.6. The line is less steep, and so the Gradient is smaller.
