I have an array of 200 elements. I want to divide this array into 25 parts and find the RMS values of these parts and print 0 if it is less than 20, 1 if it is greater. Example signal1[200] Output data[8]={0,1,0,0,1,0,1,1) I find code for RMS calculation #include <stdio.h> #include <math.h> double rms(double* v, […]

I want to use geom_text_repel to have my labels lie as close to the edge of a pie graph as possible unless the percent is under a certain value, in which case the label should be nudged further away and connected with a line. I adapted a solution from Move labels in ggplot2 pie graph […]

No Comments on Logic of recognize digits using neural network

the task is to recognize the digits (0-9) represented by the 5×6 bitmap by means of a neural network and use the backpropagation algorithm for this. I understand it like this, I have a 5×6 bitmape, i.e. the input layer neurons are 30, in the hidden layer e.g. 17 and in the output layer 10 […]

Tags 0, 0) yes?. I introduce an example to learn, 0]. Then I do the same for the hidden network. If I now enter a bitmape representing the number zero, 1, and for example, and on its basis I can see where the greatest value is, both from the interval (-1, for 1 input neuron I have weights [1, for example, I count the output of the entire network, I expect the result (1, I have a 5x6 bitmape, I introduce an example which, i.e. the input layer neurons are 30, in the hidden layer e.g. 17 and in the output layer 10 (each one corresponds to the number 0-9). How is the logic of the entire network suppo, it shows me to which digit the entered value the example is the most similar. I want you to tell me if I understand correctly all the logic, it updates the weights in the hidden layer (no input layer, shows the number 7 (it differs from this example 7 on which the network was learned) and I have the output vector, the error in the hidden layer (no input layer, the task is to recognize the digits (0-9) represented by the 5x6 bitmap by means of a neural network and use the backpropagation algorithm fo, then I count the neuron error in the output layer and then with the backpropagation algorithm, then I finish the lesson on this example and introduce a new one? When I "learn" the network, yes?) And what next do I introduce the next example and repeat these steps until I use all the data to learn the network and the error will n, yes?). After all
