Benchmarking algorithms with OpenML and R-package mlr
The open data platform OpenML offers a lot of dataset to evaluate algorithms. It offers datasets that can be used for classification and regression. It is accessible via the web page or via several programming languages like Java, Python and R.
I am performing a benchmark study with datasets from OpenML and classification and regression algorithms from the mlr package, which provide standardized interface to many of the algorithms implemented in R and easy evaluation with resampling strategies like cross-validation.
The comparison can be found on this github repository: benchmark-mlr-openml.
I will soon post a summary about the results.
Another comparison just between random forest and logistic regression is done by Raphael: BenchmarkOpenMl.
