| # MSL (TsFile) |
|
|
| Apache TsFile version of the `MSL` anomaly-detection subset of |
| [`thuml/Time-Series-Library`](https://huggingface.co/datasets/thuml/Time-Series-Library). |
|
|
| ## Overview |
|
|
| Mars Science Laboratory rover telemetry (55 channels) for anomaly detection. |
|
|
| - **Train:** 58,317 rows. |
| - **Test:** 73,729 rows. |
| - **Channels:** 55. |
|
|
| The train and test segments are stored as two separate TsFiles |
| (`MSL_train.tsfile` / `MSL_test.tsfile`), preserving the original split. Labels |
| are stored as separate CSV sidecar files in `labels/`. |
|
|
| ## Schema (TsFile structure) |
|
|
| - **Time** (INT64, milliseconds) - row index * 1000 ms. The `.npy` source has no |
| timestamp, so this is a monotone 1 Hz proxy axis. |
| - **FIELD** (55 channels, FLOAT) - the sensor/metric channels. |
| - **Labels** (CSV sidecar) - `labels/MSL_train_label.csv` and |
| `labels/MSL_test_label.csv` contain `Time,label`. The train label file is all |
| 0; the test label file carries the per-timestep anomaly labels. |
|
|
| No channels or rows are dropped. Labels are not stored inside the TsFile feature |
| tables. |
|
|
| ## Usage |
|
|
| Read the `.tsfile` files with the Apache TsFile Java or Python SDK. Join labels |
| from the sidecar CSV files by `Time` within the matching split. |
