pub struct GibbsSampler {
pub burn_in: usize,
pub num_samples: usize,
pub thinning: usize,
}Expand description
Gibbs sampling for approximate inference.
Uses Markov Chain Monte Carlo to sample from the joint distribution.
Fields§
§burn_in: usizeNumber of burn-in samples to discard
num_samples: usizeNumber of samples to collect
thinning: usizeThinning interval (keep every N-th sample)

impl GibbsSampler
Sourcepub fn new(burn_in: usize, num_samples: usize, thinning: usize) -> Self
pub fn new(burn_in: usize, num_samples: usize, thinning: usize) -> Self
Create with custom parameters.
