Data Fields
HDF5 arrays are loaded sample-first by src/sparsewake/data.py.
| Field | Loaded shape | Description |
|---|---|---|
X_raw |
[N, 6, 3] |
Wake-plus-potential per-sensor induced velocity features. |
X_wake_raw |
[N, 6, 3] |
Wake-only component where available. |
X_potential_raw |
[N, 6, 3] |
Potential-only component where available. |
X_external_raw |
[N, 6, 3] |
External neighbor signal in self-signal datasets. |
X_self_raw |
[N, 6, 3] |
Self-generated signal in self-signal datasets. |
X_total_raw |
[N, 6, 3] |
External-plus-self signal in self-signal datasets. |
y |
[N, 6] |
delta_x, delta_y, theta_rel, sin_phi, cos_phi, phi. |
groups |
[N] |
Wake phase index. |
pose_id |
[N] |
Pose index for pose-holdout when present; otherwise derived from phase blocks. |
region_id |
[N] |
Region code: 1 close wake, 2 near side, 3 mid wake. |
sensor_world_positions |
[N, 6, 2] |
Sensor coordinates for each sample. |
Raw velocity feature channels are body-frame u, body-frame v, and speed magnitude.
