How to set the number of samples in the training set and test set during training

[ChengQIAN93]

Dear all,

I am confused with training set and test set

1. Is the ratio of test set to training set required? Is there a recommendation? train set : test set = 1:1 or other value ？

2. For example, using dpdata to generate set.000 and set.001, is set.001 used in dp train or dp test?

Thank you and looking for your reply.

Hi Cheng!

The last set is used as testing set, while the rest sets are used as training sets.
You can find for information about preparing the data here:

Regarding the ratio between training and testing data, that depends on the size of your dataset
But using around 20% of the data as testing data is a good start.
