WebEssentially, backpropagation evaluates the expression for the derivative of the cost function as a product of derivatives between each layer from right to left – "backwards" – with the gradient of the weights between each layer being a simple modification of the partial products (the "backwards propagated error"). WebErf may be expressed in terms of a confluent hypergeometric function of the first kind as (25) (26) Its derivative is (27) where is a Hermite polynomial. The first derivative is (28) and the integral is (29) Erf can …
Derivative of Error Function - ProofWiki
WebSep 18, 2016 · Note: I am not an expert on backprop, but now having read a bit, I think the following caveat is appropriate. When reading papers or books on neural nets, it is not uncommon for derivatives to be written using a mix of the standard summation/index notation, matrix notation, and multi-index notation (include a hybrid of the last two for … WebMar 22, 2024 · [23] Jumarie G., Modified Reimann-Liouville derivative and fractional Taylor series of non-differentiable functions further results, Comput.

derivative - Backpropagation with Softmax / Cross Entropy
WebSince the error function can be decomposed into a sum over individual error terms for each individual input-output pair, the derivative can be calculated with respect to each input-output pair individually and then combined at the end (since the derivative of a sum of functions is the sum of the derivatives of each 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.
