    pub d_v_bnlmhp: F<B, 6>,

}

Per-input gradients produced by combined_backward for the Single-SSD. Adds d_gamma_bnlh and d_scale_bnlh over the double-ssd form crate::mamba3::double_ssd::ssd::serial_recalculated::combined_backward::CombinedGrads.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

d_v_bnlmhp: F<B, 6>

Gradient of the raw input v.

d_da_bnlh: F<B, 4>

Gradient of Δ·A (da).

d_b_bnlmhr: F<B, 6>

Gradient of the input projection B.

d_c_bnlmhr: F<B, 6>

Gradient of the output projection C.

d_gamma_bnlh: F<B, 4>

Gradient of the same-step trapezoid weight γ.

d_scale_bnlh: F<B, 4>

Gradient of the key scale scale = γ + (1−λ₊₁)·Δ₊₁.

d_initial_state_bhpr: F<B, 4>

Gradient of the initial SSM state.
