Path storage in the particle filter
This article considers the problem of storing the paths generated by a particle filter and more generally by a sequential Monte Carlo algorithm. It provides a theoretical result bounding the expected memory cost by T + CN log N where T is the time horizon, N is the number of particles and C is a con...

Summary: | This article considers the problem of storing the paths generated by a particle filter and more generally by a sequential Monte Carlo algorithm. It provides a theoretical result bounding the expected memory cost by
T
+
CN
log
N
where
T
is the time horizon,
N
is the number of particles and
C
is a constant, as well as an efficient algorithm to realise this. The theoretical result and the algorithm are illustrated with numerical experiments. |
