UniformProbeDerivativesKind

class t3toolbox.backend.uniform_fitting.UniformProbeDerivativesKind

Bases: _UniformKind, t3toolbox.backend.fitting.ProbeDerivativesKind

The uniform twin of ProbeDerivativesKind.

The forward / residual are the packed jets (d,)+(order+1,)+W+C+(N,) – order at axis 1, after the mode index d – so omega sits at mode_axis=0, order_axis=1. The ragged kind’s order-leading placement would broadcast omega over d here.

Methods

precompute(frame_data, s)	The reusable frame sweep at frame for sample (computed once per local model).
forward(v_sc, s, frame_data, sweep)	The bare Jacobian J v (no gauge).
transpose(r, s, frame_data, sweep)	The bare transpose J^T r, summed over the sample stack W; raw (dU, dG).
point_forward(x_sc, s)	The point operation S(x) -- what the residual is measured against.
take(sample, data, idx)	Gather a flat W subset of (sample, data) -- the default minibatch draw's layout hook.
