An announcement, which might be of some interest:

In the period 2022-2024, myself and a number of other postdocs on the "CoSInES" and "Bayes4Health" EPSRC grants were involved in organising a number of internal tutorial workshops, on topics relevant to researchers in computational statistics.

New material on the O(T log T) coupling algorithms:
• Example where we use unbiased gradients for maximum likelihood estimation
• Generalised coupling algorithm which can handle potentials/weights that depend on current and previous state (coupling of conditional marginal particle filters)

We revised our paper on conditional backward sampling particle filter mixing times arxiv.org/abs/2312.17572. We prove (under strong mixing) that their mixing time is O(log T), where T is time horizon, with fixed number of particles. The proof is based on implementable couplings.

The conditional backward sampling particle filter (CBPF) is a powerful Markov chain Monte Carlo sampler for general state space hidden Markov model (HMM) smoothing. It was proposed as an improvement o...

Interesting - we had a similar problem in the diffuse initialisation paper doi.org/10.1007/s112... but you have probably something else in mind.

We revised our paper about particle filter forgetting: arxiv.org/abs/2309.08517. Substantial new content:
• Propagation-of-chaos bounds (TV distance between law of q particles out of N and i.i.d. draw from the ideal filter) which vanish if q = o(N)
• Method for handling out-of-sequence measurements

Scatter plot showing total variation distances in an example, with respect to subset size q and number of particle N, and lines which indicate different asymptotics.

Choosing (X_n,Y_n) such that n^α (Xₙ−x) = Z = n^β (Yₙ−y) for all n suggests that there is little you can get from this assumption?
