added support for reading CSV files #271

Open

csoltenborn wants to merge 3 commits into starlibs:dev from csoltenborn:csv_import

csoltenborn commented Nov 29, 2021

This PR adds support for importing CSV files into a dataset by implementing CSVDatasetAdapter.deserializeDataset().

column types are selected based on the data: IntBasedCategoryAttribute must be chosen by passing the according column names, NumericAttribute is selected if the column only contains numeric elements, and else StringAttribute is chosen
empty cells as well as lines with the wrong number of entries are ignored

Note that I'm not sure whether my implementations of IDataSetDescriptor as well as ReconstructionInstruction make sense - please check.
