Derivative of error function

WebSo the derivative of this is two X plus five. So it should have been two X plus five times the second thing. So times sine of X. Times, we do it in another color. Time the sine of X, and then to that he would add the first thing, which is X squared plus five X times the derivative of the second thing. So the derivative of sine of X is cosine of X. WebNov 19, 2024 · Here the alpha term, α, is known as the learning rate and is multiplied by the derivative of our Loss function (J) (Please recollect that we have discussed how to calculate the derivatives of a function in the chain rule of derivatives document). We subtract this product from our initial weight to update it.
