5.6. pypfilt.params¶
The pypfilt.params
module provides default values for the particle
filter parameters:
-
pypfilt.params.
default_params
(model, time_scale, max_days, px_count, prng_seed)¶ The default particle filter parameters.
Memory usage can reach extreme levels with a large number of particles, and so it may be necessary to keep only a sliding window of the entire particle history matrix in memory.
Parameters: - model – The system model.
- time_scale – The simulation time scale.
- max_days – The number of contiguous days that must be kept in memory (e.g., the largest observation period).
- px_count – The number of particles.
- prng_seed – The seed for the pseudo-random number generators.
