Detailed Description

template<typename... Placed>
class Emrys::Factors< Placed >

The factors of a product, each placed by tag path with on() or onEach(), in no space yet: a Product once placed in one (decisions.md [product-factors]).

Paths name blocks by type, so the factors fit every instance of a space type, whatever its counts. Product{space, factors} places them in one instance, resolving each path's coordinates and each onEach()'s count there. It is not a distribution, since without sizes it has no density. Additive measurement noise may be given as one (see additiveNoise()), and an update places it in each measurement's space.

auto const landmarks = Factors{onEach<Landmarks>(GaussianParams<Landmark>{zero, P})};
auto const prior = Product{space, landmarks};  // I (x) P over space's count of landmarks

Template Parameters

the factors, as on() and onEach() return them, in order
