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.
