Enum Support 

pub enum Support {
    Real,
    Positive,
    Unit,
}

The support of a continuous model latent, used to pick a matching variational family.

Mean-field VI is only correct if each variational factor lives on the same support as the model latent it approximates: a Normal guide placed on a strictly-positive or unit-interval latent proposes out-of-support values whose model log-density is -inf, collapsing the ELBO. Support lets callers declare the intended support so guide construction can select the right family (see MeanFieldGuide::add_latent).

Variants

Real

(-∞, +∞): approximated by a VariationalParam::Normal factor.

Positive

(0, +∞): approximated by a VariationalParam::LogNormal factor.

Unit

(0, 1): approximated by a VariationalParam::Beta factor.
