Formula mismatch in nvideo

#1

in MLP 05 video sir has written derivative of sigmoid function in the formula for output layer while in backpropagation code the formula used is delta3= y_-y

#2

please help wwhy is noone responding

Hey @sagartiwari1711,

The formula for loss used in derivation was Mean Squared Error but in practice, we avoid using MSE since it causes local minima and it’s difficult to converge. So we use binary cross-entropy loss which results as y_- y.

I hope your doubt is cleared.
