SparseWake/sparsewake
SparseWake SparseWake is a synthetic benchmark for sparse temporal hydrodynamic sensing. ICLR 2027 release The expanded release adds controlled multi-source mixtures and common-prior nearest-source tasks, with complete core data banks, reference checkpoints, a small review supplement, and reproduction code with a frozen wake-library input. Download release iclr2027-v1.0rc2 The version page lists the three archives, exact sizes, checksums, extraction instructions… See the full description on the dataset page: https://huggingface.co/datasets/SparseWake/sparsewake.

1# Data Fields2 3HDF5 arrays are loaded sample-first by `src/sparsewake/data.py`.4 5| Field | Loaded shape | Description |6|---|---:|---|7| `X_raw` | `[N, 6, 3]` | Wake-plus-potential per-sensor induced velocity features. |8| `X_wake_raw` | `[N, 6, 3]` | Wake-only component where available. |9| `X_potential_raw` | `[N, 6, 3]` | Potential-only component where available. |10| `X_external_raw` | `[N, 6, 3]` | External neighbor signal in self-signal datasets. |11| `X_self_raw` | `[N, 6, 3]` | Self-generated signal in self-signal datasets. |12| `X_total_raw` | `[N, 6, 3]` | External-plus-self signal in self-signal datasets. |13| `y` | `[N, 6]` | `delta_x`, `delta_y`, `theta_rel`, `sin_phi`, `cos_phi`, `phi`. |14| `groups` | `[N]` | Wake phase index. |15| `pose_id` | `[N]` | Pose index for pose-holdout when present; otherwise derived from phase blocks. |16| `region_id` | `[N]` | Region code: 1 close wake, 2 near side, 3 mid wake. |17| `sensor_world_positions` | `[N, 6, 2]` | Sensor coordinates for each sample. |18 19Raw velocity feature channels are body-frame `u`, body-frame `v`, and speed magnitude.20 21
