I finished business school 25 years ago where I studied statistics and math. So happy to see that neural networks are fundamentally just a (much) more advanced regression analysis.

@statquest

7 ай бұрын

BAM!!! Thank you for supporting StatQuest! Yes, neural networks are a lot like regression, but now we can fit non-linear shapes to the data, and we don't have to know in advance what that shape should be. Given enough activation functions and hidden layers, the neural network can figure it out on its own.

this video is a gem. I had to watch it a few times and like in gradient descent, I went closer to the target level of knowledge with each step :)

May I say .... You are such a good teacher that it is most enjoyable to watch your videos. I am proficient in statistics (via university econometrics 101) ... and I did not realise all those fancy terms in machine learning are actually concepts that are common items in the stats that I learned in the 1970s, e.g., biases and weights, label, activation functions etc. Anyway, I can see that a lot of viewers appreciate your work and teaching. I have also 'updated' myself. Thank you.

9:00 at this moment I realised I'm watching the best math content on earth, because you never see simple stuff like this being given attention to. Luckily I already know how summation symbol works, but I didn't know it in the past, and nobody cared to explain. But it's just not about the summation symbol, imagine the other 1000 small things somebody might not understand, and doesn't realise they don't understand, because it's been skimmed over

This is what she said

Back propagation (aka finding w's and b's) start with b_final=0. you'll notice that error = (actual - predicted)^2 is really high. so you find the gradient descent of squared error wrt b_final and find out the value of b_final for which the squared error is minimum. that is your optimal b_final. gradient descent: derivative of sum of squared errors wrt b_final = derivative of sum of squared errors wrt predicted value y * derivative of y wrt b_final. d(y observed - y predicted)^2/d(y predicted) = -2*(y observed - y predicted) d(y predicted)/d(b_final) = d(sum of all those previous curves obtained through each node of the layer + b_final)/d(b_final) = 0+0+0....+0+1=1 take the predicted curve ke x values and find the derivative/slope. step size = slope*learning rate. new b_final = old b_final - step size. keep repeating until slope touches 0. this is how gradient descent works and you've found your optimal b_final.
