Sample Machine Learning datasets on DataHub #33
Comments
You can for example use any data set from OpenML and extract the relevant info to create the data package. Example in R: library("OpenML")
eyedat <- getOMLDataSet(data.name = "eeg-eye-state")
str(eyedat) The same can be done in python, java, ... (whatever you prefer, see OpenML website). |
@HeidiSeibold great. Do you have any recommendations on a top-5 "getting started" datasets you'd recommend for us to data package? |
There is a collection called OpenML 100 with interesting (classification) data sets. It was collected as a quick way to do benchmarking with OpenML. Maybe the first 5 of those 😉 |
@HeidiSeibold thanks - if you have any tips on which ones you'd especially recommend let us know. @Mikanebu please take a look through these datasets and see how they work and if there any that you think would be good From my own quick browse i found:

@rufuspollock ok, I will take a look |

@HeidiSeibold we've started data packaging some machine learning datasets here http://datahub.io/machine-learning Any feedback or suggestions for next steps would be very welcome 😄 |
Cool, thanks 🎉 . So there is at least one data set that is both in your collection as well as on OpenML: I guess a first step now would be to check:
Is the R package for data packages stable yet? That would make it very easy because then we could just convert between the file formats in R, I think. |
FIXED! We added new datasets from open-ml at datahub.io/machine-learning and wrote a blog post about ARFF format specifically https://datahub.io/blog/attribute-relation-file-format-arff |
Awesome, thanks @Branko-Dj! Do you have code for the transformation from ARFF to data package that we could share? |
@HeidiSeibold Currently we would do it by transforming arff file to csv by using pre-existing scripts (https://github.com/haloboy777/arfftocsv for example) and then create data package for the csv file. |
Many potential users come from a machine learning context and may be interested in sample machine learning datasets so let's get some up on the DataHub.
