to_lightsvm_format(dataset, out[, ...]) | Export dataset into LightSVM format :Parameters: dataset : Dataset out : Anything understanding .write(string), such as File targets_attr : string, optional Name of the samples attribute to be output domain : {None, ‘regression’, ‘binary’, ‘multiclass’}, optional What domain dataset belongs to. |
