Particle Markov chains over an injected sweep operation. World execution is the sweep's responsibility; normalization, retention and accept/reject live here, shared by savepoint and canonical-world drivers.

normalized clj/s

(normalized measure)

Normalize a settled sweep for pooling. Impossible particles remain zero.

pgibbs clj/s

(pgibbs sweep
        iterations
        {:keys [seed pick-key initial-pick first-iteration pick-offset]
         :or {pick-key :org.replikativ.foerster.particle-mcmc/pick
              initial-pick :initial
              first-iteration 0
              pick-offset 0}})

Run conditional particle sweeps, pooling their normalized output. sweep receives [key retained seed]; the initial retained argument is nil. Seed role options preserve existing entry-point streams during consolidation.

pimh clj/s

(pimh sweep
      iterations
      {:keys [seed accept-key first-iteration]
       :or {accept-key :org.replikativ.foerster.particle-mcmc/accept
            first-iteration 0}})

Run an independent particle MH chain. sweep receives [key retained seed] and returns an awaitable weighted sweep; retained is nil. The sweep must supply a valid evidence estimate. It owns and settles its execution worlds.

retained-choices clj/s

(retained-choices trace)

Retained choices from a settled Sample trace, excluding deterministic and observed sites. The conditional sweep interprets these at its own frontier.
