# 3.4. Descriptor "se_e3"

The notation of se_e3 is short for the Deep Potential Smooth Edition (DeepPot-SE) constructed from all information (both angular and radial) of atomic configurations. The embedding takes angles between two neighboring atoms as input (denoted by e3).

A complete training input script of this example can be found in the directory

\$deepmd_source_dir/examples/water/se_e3/input.json


The training input script is very similar to that of se_e2_a. The only difference lies in the descriptor <model/descriptor> section

	"descriptor": {
"type":		"se_e3",
"sel":		[40, 80],
"rcut_smth":	0.50,
"rcut":		6.00,
"neuron":		[2, 4, 8],
"resnet_dt":	false,
"seed":		1,
"_comment":		" that's all"
},


The type of the descriptor is set by the key type.
