Let's explain in previous videos that the whole idea behind deep learning is the back propagation algorithm. So in this video where the viewers are expecting an explanation of the back propagation algorithm, let's write a bunch of lines and tell the viewers "I think you understood that this is the back propagation algorithm". Bravo.

For W1=2*rand(20, 25)-1 i think it should be W1=2*rand(25,20)-1. According to your source code the first parameter i.e. 25 represent the number of the previous layer, whereas the second parameter i.e, represents the number of nodes related to the next layer.
@skalar-haubitze16194 жыл бұрын
It is correct since it is exactly the other way around: the first number represents the number of the next layer, whereas the second parameter represents the number of the previous layer. Also I believe that if you would switch these two parameters by mistake you would run into an error because of wrong matrix dimensions.

Thank you. You asked a good question. 1) please plot the output of 'softmax' function separately. It will answer your question. It is difficult it express it properly using text. 2) for every pixel, there will be one input nodes. For 20*30 image, you need 600 input nodes. 3) There are two classes - (i) male and (ii) female. So two output nodes.

Teacher, there is something I don´t understand. In the section of adjustment at the DeepLearning function: adjustment_of_w4 = alpha*delta*output_of_hidden_layer3'; adjustment_of_w3 = alpha*delta3*output_of_hidden_layer2'; adjustment_of_w2 = alpha*delta2*output_of_hidden_layer1'; adjustment_of_w1 = alpha*delta1*reshaped_input_Image'; alpha is a real number, delta is a (5x5) matrix multiplied for (output_of_hidden_layer3') wich is a (1x20) matrix... I don´t get this part And similar for the rest: delta 3 is a (20x5) matrix, and (output_of_hidden_layer2') is a (1x20) matrix delta 2 is a (20x5) matrix, and (output_of_hidden_layer1') is a (1x20) matrix delta1 is a (20x5) matrix, and (reshaped_input_Image';) is a (1x25) matrix How are this multiplication among matrix possible? and I know it works perfectly because I did the exercise Hope you might read and answer this message.

Hi, Nuruzzaman. Your video "Neural Network using Matlab" doesn't show its comments (at least in my PC). For this reason, I want to congratulate you for that great video. Your explanations are very clear. I wanted to create a more general version of your SGD_method() to solve a exercise that I must to do, however, when I arrived to the calculation of delta and deltaweight, I realized that both calculations would produce incompatible multiplication of matrices. Please let me show you: delta = output * (1 - output) * error; If I treat output like a array, I don't know the procedure to calculate delta. In my opinion it's impossible, because if (for instance) output has a order 2x1, (1 - output) also would have this order. Then we will have a multiplication of 2x1 and 2x1... and then we have the array error. Something similar happens with deltaWeight. I would like to know if you can make a video to show how to handle the training and testing of a perceptron with more than one output. My bigger doubt is: how is affected the matrix of weights when a error appears in (for instance) the output 1? The error can affect every element of the matrix or only the weights related with that output? Best regards and congratulations again!
