bias(thetha) calculated =previous_theta +learning rate*delta
your equation is correct thank u bro .
how to calculate delta ?
@@muhammadharis7318 we have calculated it before
For example we calculate theta(6)=previous theta (6)+learning rate*delta(6)
Internet says it is bias(new)=bias(old) - learningrate × delta
This video helped me out so much. I was so confused by my class meterials, this really cleared things up for me. Also, maybe remind people that beta is x0 and w0

Thank you. Could you please give a clear guide on how to update the bias?
delta bias i = n(learning rate) * Sj(Error Term)
bias i (new) = delta bias i + bias i (old)
Sir how to find the weight for bais term? i am unable to understand
Hi Mahesh, thank you for your videos. They are super useful.

Thank you so much for your lessons, they've been really helpful.
Clarification: Why is it that in calculating Error, you are not taking the square and dividing by 2
E=1/2(t-y)^2
I look forward to getting your response.
Many thanks
How To calculate theta 6???
Your explaination is crystal clear and well simplified. Please make more such videos on deep learning using different algorithms.(ReLU etc.,)
Ok

Sir in dervatiom video you said error is
Error = 1/2 £(td-od)²
Here you selected (target - actual) with no square and not even divided by 2??
It's the derivative
If I use this method not derivation method both have same result?
@@jetnetgaming3594 but the derivative should be used during backprop only, when in forward pass if we are calculating error we should use the formula as it is. anyways i think in the video they have demonstrated the error for the backprop purpose only hence they have calculated the derivative value. Can u please also confirm if these formulas and the chain rule derivation are the same?
How to update bias values
how do you update the bias value ? which formula ?
i don't believe the bias value changes, only its weight. to change the bias weight, you use the same formula used to change the input/hidden nodes weight
new bias weight(0,6) = (previous bias weight) + (learningRate*delta6*biasValue)
Thanks for lecture. May I know how the formula will change if I use ReLu activation function?
Thanks for tutorial , helped me a lot

how bias are updated
For bias updation,
learning rate * y6
Add this with old bias
Eta * delta for particular node
Thank you so much sir. Its really good

updation of bias given in:
vid-83
ruclips.net/video/tTjcakAuHPI/видео.htmlsi=zvK_x5-JylavBZOz
(new)bias = (old)bias + Δbias
Δbias = learning rate*δj
δj is the error term Oj*(1-Oj)*(Tj-Oj)
thank u so much
👍
How to update the bias, Sir?
Use same formula for as we used in calculation of changing whieghts but take input weight of bias as 1 so final formula will be ⌂ = n * sj ,after that calculate new bias by adding old bias and the bias we calculated.
Thanks for saving me
