Thanks @mofeilu !
I will try to add an example, but in the mean time the main relevant code would look something like this:
# model inputs
species = inputs.SpeciesNode(db_name="Z")
positions = inputs.PositionsNode(db_name="R")
# Model computations
network = networks.Hipnn("HIPNN", (species, positions), module_kwargs=network_params)
henergy = targets.HEnergyNode("HEnergy", network,db_name="E")
hcharge = targets.HChargeNode("HCharge",network,db_name="Q")
dipole = physics.Dipole("QDipole",hcharge,db_name="D")
Then the hcharge and dipole can be used in the loss function and etc. The db_name quantity specifies how the quantity is called in the database.
I am interested in using hippynn to do charge modeling, is there any working examples of training hip-nn to charges or dipole moments as in the paper "Discovering a Transferable Charge Assignment Model Using Machine Learning"?
In the example folder, I could see energy training case but no explicit charge training ones.
Thanks,
