Beautiful video. The patience, the calmness in your voice in these videos. Thank you so much

This is the best video on forward propagation in KZread. Thanks for posting such videos.

Simply the best explanations i have found if i could give part one and two a hundred likes i would...Please do more AI content you have a gift for teaching.

I 've never seen such a perfect explanation.I have faced with a problem while I was writing my kernel and searched everywhere to find a solution for understanding reason of error I ve got.Suddenly I saw the video and started to listen carefully .Thank you so much sir

I'm very happy to hear this :) Good luck to you

Thank you so much for such a simple way to teach a medium student. It was too clear and obvious to understand and learn the NN.. Love from Pakistan😀

Part 1 and Part 2 are the best explanation of these subjects going. Thanks so much Bevan. You have a real talent for explaining a difficult subject in a way that’s as easy as possible to grasp. Brilliant videos

Most amazing explanation

the best explanation so far...

Thanks a lot Bevan. Excellent insights with simplicity. Kudos!

Thank you so much. This the first explanation of forward propagation in neural networks, that I actually understood.

Awesome to hear. Good luck!

Excellent presentation! I wish a intro in Transformer Architecture, which today replaces many NN (CNN,RNN,…).

Dear Bevan, You have presented both the forward and backward propagation concepts in an exceptional manner, especially the example that you have chosen for doing so. The majority of ANN tutorials stick to 'cat-dog' kind of categorical examples. I have one query though. Do you recommend the use of a non-linear activation function in the output layer? And if yes, which non-linear activation function will you prefer for continuous problems. The thing to keep in mind while choosing this output layer activation function is that it should be able to provide an output which can exceed 1 or can be less than 0 or -1. Sigmoid or tanh activation function in the output layer will not allow us to have such 'greater than 1 or less than 0 / -1' outputs. I hope to hear from you. Thanks!

I'm currently taking an AI course but I.must say your explanation is.more understandable. Thank you.

The best content I have found, thanks for such a detailed explanation!

Thank You. Very Informative

so perfect brother nice job

Stochastic Gradient Decent. It is Stochastic since it Randomly shuffle samples in the training set.

May I ask how you can determine the bias to be added in z1 calculation?

This is a fantastic explanation, but you'll need some knowledge of machine learning from scratch, particularly linear and logistic regression. This is perfect and exactly what I needed to understand NN. Liked and subbed.

Awesome

Great work Thankyou

Why haven't we performed Activation function on Ypred ??

Thanks for your explanation! How do you choose the weights? or its a random decision? Thank u in advance!

Hi Lucia. Yes it was a random decision. For a more thorough explanation of the initial values of the weights, check out Andrew Ng (kzread.info/dash/bejne/aJatmLqao8KxmNI.html). Good luck!

Thanks for this! clear and straight to the point. The simplest example I've seen so far. As regards biases, does this apply to the RBF Neural Networks as well? For instance, if the input layer has a bias unit, do we add the bias during forward propagation? Thanks

I was wondering why didn't you write the active fucnton in your output neuron? is there a specific reason?

@bevansmithdatascience9580

Most likely because it is just a linear summation of the inputs. There was no need to pass it through a non linear activation function

Why do we only use 2 nodes?

@bevansmithdatascience9580

It is just an example. There can be as many nodes/neurons as you wish. I just used two for this example

What is the point of saying "okay" every three seconds? Imagine people listening to your videos multiple times, it makes a lot of "okay, okay, okay, okay, okay". Which is just "noise" in the information that's actually blocking the material!

@@joachimguth6226 You are right, it could have been sugarcoated more. Unfortunately this feedback to benefit and improve the video/channel is answered with insult and disrespect. When a teacher starts insulting the audience with disrespect, it's a clear sign that he/she isn't the right character to be a teacher, but just uses information as an excuse to feel above others.
