# PULSE-sample — Representative Single-Recording Subset

This is a small representative subset of the **PULSE** dataset, hosted as a separate
Hugging Face repository so that NeurIPS 2026 reviewers can inspect data quality and
schema without downloading the full 85 GB release.

> **Full dataset:** [`velvet-pine-22/PULSE`](https://huggingface.co/datasets/velvet-pine-22/PULSE)

## What this sample contains (~284 MB total)

A single complete recording — **`v1/s1`** (volunteer 1, scenario S1 "Office desk
organization", ~101 s) — with **all five non-visual sensor modalities** plus the
synchronized scene-camera video, action-segment annotations, and the global metadata
files needed to interpret everything.

## How to use this sample

```python
import pandas as pd

# Load all five modalities for the single recording
ROOT = "data/v1/s1"
emg      = pd.read_csv(f"{ROOT}/aligned_emg_100hz.csv")
eyetrack = pd.read_csv(f"{ROOT}/aligned_eyetrack_100hz.csv")
imu      = pd.read_csv(f"{ROOT}/aligned_imu_100hz.csv")
mocap    = pd.read_csv(f"{ROOT}/aligned_mocap_100hz.csv")
pressure = pd.read_csv(f"{ROOT}/aligned_pressure_100hz.csv")
print(f"Aligned shapes (T, D): {[x.shape for x in [emg, eyetrack, imu, mocap, pressure]]}")

# Load the dense segment annotations
import json
with open("annotations/v1/s1.json") as f: ann = json.load(f)
print(f"{len(ann['segments'])} action segments")
```

All time series are sub-frame aligned (<10 ms) on a shared 100 Hz timebase. The first
sample of every modality file corresponds to t = 0 of the trimmed scene-cam video;
total length matches `metadata/recordings.csv` row `v1s1` (`duration_sec`,
`n_samples_100hz`).

## How this sample was created

Selected by the dataset authors as a representative recording: scenario S1 "office
desk organization" was chosen because it contains a typical mix of grasp / move /
place / adjust primitives without unusually short or long sub-tasks; v1 was chosen
because it has all five modalities present and full-length scene-cam video.

The full 337-row `metadata/recordings.csv` is included so reviewers can see exactly
where this recording sits in the train/test split scheme and which other recordings
exist; the global Croissant metadata is on the main repo.
