DOS model.

Parameters:

descriptor: Descriptor
fitting_net: Fitting net
type_embedding: Type embedding net
type_map: Mapping atom type to the name (str) of the type. For example type_map[1] gives the name of the type 1.
data_stat_nbatch: Number of frames used for data statistic
data_stat_protect: Protect parameter for atomic energy regression
