R help - Mar 2022 - Looking for package for data generation for classification and regression

Dear All,

I am in need of generating artificial data for machine learning
classification and regression analysis. What I am looking for is
something similar to Python sklearn.datasets.make_classification and
sklearn.datasets.make_regression:

https://scikit-learn.org/stable/modules/generated/sklearn.datasets.make_classification.html

https://scikit-learn.org/stable/modules/generated/sklearn.datasets.make_regression.html

I have searched CRAN for something similar, but found nothing. Could
someone please help me with this?

Thanks in advance,

Paul

Hi Paul. Have you considered just going onto Kaggle and GitHub and 
searching for some of the many freely available real datasets that are 
posted there? I'm seeing a lot of productivity there days with research 
focused on data generation, and not just on creating algorithms and 
predictive models. Which is a good thing for us ;)

One of the current research papers I'm working on now is based on mining 
a dataset I discovered on Kaggle a few months back and trying to create 
a novel solution for that. Proper credit will of course be provided in 
the citation references for the data provider.


Thanks,
Tom

Not sure if this helps, but at least for classification and clustering, there is
the MixSim package on CRAN which provides classification datasets according to
an overall overlap measure.


Hope this helps!
