Expand description

Hyper-parameters for EsMetaTrainer.

Fields§

§population: usize

Number of weight perturbations evaluated per iteration. Rounded up to the next even number, because perturbations are drawn in mirrored pairs.

§iterations: usize

Number of ES iterations.

§sigma: f64

Perturbation standard deviation σ. Too small and the finite-difference signal drowns in rollout noise; too large and the estimate stops being the gradient of anything local.

§meta_learning_rate: f64

Adam step size applied to the estimated meta-gradient.

§horizon: usize

Inner-loop rollout length: how many optimizer steps each evaluation runs.

§seed: u64

Seed for the perturbation draws, so a training run is reproducible.
