to_numeric: The KL-divergence evaluted elementwise on the input value.
sign_from_args: The atom is positive.
is_atom_convex: The atom is convex.
is_atom_concave: The atom is not concave.
is_incr: The atom is not monotonic in any argument.
is_decr: The atom is not monotonic in any argument.
.grad: Gives the (sub/super)gradient of the atom w.r.t. each variable
.domain: Returns constraints describng the domain of the node
xAn Expression or numeric constant.
