Arguments

x

An Expression or numeric constant.

y

An Expression or numeric constant.

object

A KLDiv object.

values

A list of numeric values for the arguments

idx

An index into the atom.

Methods (by generic)

• to_numeric(KLDiv): The KL-divergence evaluted elementwise on the input value.

• sign_from_args(KLDiv): The atom is positive.

• is_atom_convex(KLDiv): The atom is convex.

• is_atom_concave(KLDiv): The atom is not concave.

• is_incr(KLDiv): The atom is not monotonic in any argument.

• is_decr(KLDiv): The atom is not monotonic in any argument.

• .grad(KLDiv): Gives the (sub/super)gradient of the atom w.r.t. each variable

• .domain(KLDiv): Returns constraints describng the domain of the node

Slots

x

An Expression or numeric constant.

y

An Expression or numeric constant.
