# koch_test

This repository contains a TsFile conversion of the original Hugging Face
dataset [`MoofireX/koch_test`](https://huggingface.co/datasets/MoofireX/koch_test).

## Source Dataset

The source repository contains one Parquet split and LeRobot metadata files:

```text
data/train-00000-of-00001.parquet
meta_data/episode_data_index.safetensors
meta_data/info.json
meta_data/stats.safetensors
```

The converted repository keeps the same top-level structure:

```text
data/train.tsfile
meta_data/episode_data_index.safetensors
meta_data/info.json
meta_data/stats.safetensors
```

## Source Schema

The source Parquet split has 2,755 rows and 7 columns:

| Column | Source type | Conversion |
|---|---|---|
| `observation.state` | fixed-size list float[6] | flattened to `state_0` ... `state_5` |
| `action` | fixed-size list float[6] | flattened to `action_0` ... `action_5` |
| `episode_index` | int64 | FIELD |
| `frame_index` | int64 | FIELD |
| `timestamp` | float | renamed to `episode_timestamp_s` FIELD |
| `next.done` | bool | renamed to `next_done` FIELD |
| `index` | int64 | renamed to `sample_index` FIELD |

## Conversion Notes

- Source format converted to TsFile: lowercase `data/train-00000-of-00001.parquet`.
- Converted format: TsFile table model.
- Output file: `data/train.tsfile`.
- Table name: `koch_test`.
- TAG column: `episode_id`, synthesized from `episode_index`.
- Time column: synthesized from `frame_index * 100 ms`.
- The original `timestamp` value is preserved as `episode_timestamp_s`.
- `observation.state` and `action` are not dropped semantically; each 6-element
  vector is expanded to scalar fields because TsFile import requires scalar
  columns.
- Row count is preserved: 2,755 source rows -> 2,755 TsFile rows.

## Metadata

The source `meta_data/info.json` reports:

```json
{
  "codebase_version": "v1.6",
  "fps": 30,
  "video": true,
  "encoding": {
    "vcodec": "libsvtav1",
    "pix_fmt": "yuv420p",
    "g": 2,
    "crf": 30
  }
}
```

The `meta_data/` files are mirrored unchanged from the source repository for
traceability. The TsFile conversion only uses the Parquet split.
