Expand description

One step comparison of vanilla gradient descent vs natural gradient descent.

Fields§

§logits_before: Vec<f32>

Logits before the step (reference distribution p₀).

§logits_vanilla: Vec<f32>

Vanilla update: θ ← θ − lr · g.

§logits_natural: Vec<f32>

Natural update: θ ← θ − lr · F⁻¹ g.

§euclid_vanilla: f32

Euclidean distance traveled in logit space (vanilla).

§euclid_natural: f32

Euclidean distance traveled in logit space (natural).

§kl_vanilla: f32

KL(p₀ ‖ p_vanilla) — information divergence of vanilla step.

§kl_natural: f32

KL(p₀ ‖ p_natural) — information divergence of natural step.

§fisher_rao_vanilla: f32

Fisher-Rao geodesic distance (vanilla).

§fisher_rao_natural: f32

Fisher-Rao geodesic distance (natural).
