Question:
Consider two particle filtering implementations:
Implementation 1: Initialize particles by sampling from initial state distribution and assigning uniform weights.
1. Propagate particles, retaining weights
2. Resample according to weights
3. Weight according to observations
Implementation 2: Initialize particles by sampling from initial state distribution.
1. Propagate unweighted particles
2. Weight according to observations
3. Resample according to weights
(i) [true or false] Implementation 2 will typically provide a better approximation of the estimated distribution than implementation 1.
(ii) [true or false] If the transition model is deterministic then both implementations provide equally good estimates of the distribution
(iii) [true or false] If the observation model is deterministic then both implementations provide equally good estimates of the distribution.
