Sir, you deserve a big thanks. My teacher gave me an assignment and i was searching for 2 days on youtube for weight calculation. But finally your video has done the work. It was really satisfying. Thank you sir.

[@sowmiya_rocker]

Thanks for the video, sir. I have a doubt. How did you update weights without Gradient Descent (GD) or any other optimization technique, sir? Because I read in blogs that Networks don't get trained without GD and by only using backpropagation. In other words, my doubt is how does the calculation change if we also implemented GD in this? I'm a rookie; kindly guide me, sir.

[@adityachalla7677]

gradient descent has been used in this video while updating the weights. the change in weights is done through gradient descent. But here he has not written the derivative math.

I believe for hidden units, the w_kj in delta(j) formula should have been w_jk. Namely, other way around.

[@alperari9496]

And delta(w_ji) should have been delta(w_ij), again the other way around.

[@muhtasirimran]

@Mahesh Huddar ik. You have used sigmoid function on the hidden layer. This will result in an error.

What about the bias factor??

[@halihammer]

He did not add it to keep it simple i guess. But you can add the bias by making it a third input. Then the method doesnt change you just have a new (constant) input for each layer. Normaly set to one 1 and the weight associated will act as your bias. since 1*biasWeight = biasWeight. I just added 1 to my input vector and generate an additionol weight for the weights matrix. But im also just learning an not sure if im 100% correct..

[@vinayvictory8010]

At what stage we have to stop Forward and Backward pass unti Error becomes zero

[@muhtasirimran]

this is specified as epoch and must be given in a question. There is no defined condition to stop. It really depends on your needs.

same doubt .. what is the correct method?

[@priyanshumohanty5261]

@@keertichauhan6221 I think there are different methods to compute the error. The one that this guy above has mentioned is mean square error. The one shown in the video is also correct, but using MSE or RMSE, are generally regarded as better measures.

[@chukwuemekaomerenna4396]

For a multiple data point, you use error function and for single output you make use of loss function. Loss function is error = actual - target Error function is 1/2(actual-target)square

[@chukwuemekaomerenna4396]

For a multiple data point, you use error function. Error function=1/2 summation(y actual - y target)^2. For a single data point, you use the loss function. Loss function= (y actual - y target)

[@sharanyas1565]

The errors are made to be positive by squaring.
