Work on disease data

۵۱۲/۵۰۰۰

Hello
My friends used to work on text data before
Now I have a dataset containing 18 features and 106 samples. About the disease. With two classes
There are 79 samples of healthy specimens that do not have a disease. And 25 patients are sick.
And 2 samples are unknown.
I wanted to know if I should do normalization and pre-processing?
Should I do over sampeling, under sampeling?
Is this possible in the rapidminer?
Do you know the typical process for me?
Thankful
As always, I'm grateful to help you
Everyone's happy day

Hi,
I can have a look at your data. Send your data as PM, I will answer you ASAP.

Hello

Unable to send data

Could you guide the specifications given in the data?

I'm waiting for your help

With such a small sample of both classes, I wouldn't do either upsampling or downsampling. You could try Weight by Stratification instead and use a simple machine learning model such as Naive Bayes or Decision Trees to start. But your ability to discriminate between classes may be very limited due to your small sample size. You should review the in-program tutorials for the referenced operators if you need help setting up the process, or you could post your xml of your own process if you are running into a specific problem and need more help.

Hello @student_compute

These are basic suggestions and more appropriate suggestions are given based on data. As we don't have data, you can try this.

Normalization: check if the data values have different ranges, for example (one feature has values between 1 and 10 and other feature has a value between 1000 and 10000) then you can normalize otherwise there is no necessity to do that.

Preprocessing: separate missing label samples from the data. Later you can use them to just predict values based on trained model. Use feature selection techniques if possible to see whether all 18 features are important or not.
Over or undersampling: First try without sampling and check how the models are working, if you feel that it is necessary to sample, i recommend smote for upsampling. As your data set is small, I guess downsampling is not a good Idea.

Build models using cross validation and add feature selection techniques inside this operator.

Finally, yes all these things are possible in rapidminer.

Hope this helps

Hello
Thank you very much for all the friends in the posts

I changed my data. I actually picked up another data and collected 100 data.
But I still have 18 features. 23 unsuccessful data and 75 data with successful class and 2 data with unknown class
These data are about four ball sportsmen.
Can you help me with this type of data now?
Should I increase or decrease my data over sampling or under sampling? How does this work in RapidMiner?
Is my process correct?
I sent this sample. I created.

I will be grateful. Complete your friends
(I would say that I found myself in the forum, but I did not find a solution to my problem ..)
How should I choose a visa? And how to make a model with a neural network?

Thankful

Hello
Friends

Hello @student_compute

Your sample process looks fine. If you want to incorporate feature selection and upsampling, here is the process for you. You need to try different things (different algorithms, different parameter settings) and check if the performance improves. As your data set is small, I don't recommend downsampling. Again, as we don't have access to data our suggestions are based on approximation.

Hi varunm1
Thank you so much for your guidance
How to use CNN or ANN to predict future data?
I tried everything. I did not achieve this
Can you help me this time?
Thank you very very veeeeery much

Hello,

You need to install deep learning extension in rapidminer and go through the tutorials and apply in a similar fashion. There are many factors that impact algorithm performances and you need to go through the basic principle behind these algorithms to understand their functionality and methods to improve their performance.

Hello
thank you
I installed the neural network
And I used it below

</operator>
</process>

But I do not know if my model is right or not?
And how to use ANN or CNN. I did not find an operator with these names ..!
Will it be more accurate with increasing the amount of learning rate and momentum of the neural network and therefore my model?
(One question: Does the number of hidden layers, inputs and outputs make its own operator, or can it be created by me as well?)
And (Is it possible to use zernik moment in RapidMiner?)
Please and ask for help and guidance.
Thankful
