Which is the test file for submission?

Hi,
I followed the instructions in Docs to set it up. I see there are two event files.
  1. events-validation.hdf5
  2. events.hdf5
I see both these files have events data with the differential cross-section column having a value. Which file contains the data that needs to be predicted for submission?
I'm using the functions in introduction.ipynb to inspect. This is my code.
print("Train files")
file_train_path = Path("../.aqora/data/data/events.hdf5")
abs_file_train_path = file_train_path.resolve()

print("Inspect file")
inspect_hdf5(abs_file_train_path)

print("Inspect events")
inspect_events_hdf5(abs_file_train_path)

print("Inspect random number")
inspect_random_numbers(abs_file_train_path)

print("\n")

print("Test files")
file_test_path = Path("../.aqora/data/data/events-validation.hdf5")
abs_file_test_path = file_test_path.resolve()

print("Inspect file")
inspect_hdf5(abs_file_test_path)

print("Inspect events")
inspect_events_hdf5(abs_file_test_path)

print("Inspect random number")
inspect_random_numbers(abs_file_test_path)
Thank you.

Hi @jag, the events.hdf5 file is the training data set. The events-validation.hdf5 is data that should not be used for training. It can be used to check how well the trained model predicts unknown points.

Hi @eno, the events-validation.hdf5 file is the one that needs to be predicted and submitted as a solution?

Yes. With the cross sections predicted by your model, which should only be trained using events.hdf5.

@eno One small question, in the task description, it is stated
  • randomNumbers, the parametrised phase space points (differing in dimensionality with n).
But, I checked that all the rows of randomNumbers have 5 columns. Am I missing something?

Initially the idea was to provide data for different final-state particle multiplicities. In that case, each file would have a different n (but it would be constant in each data file). So the statement about the differing dimensionality is a bit misleading, given that you are in the final form of the project only provided a single file for a single multiplicity. Sorry about that.
