+# UWaveGestureLibrary (TsFile)
+
+Apache TsFile version of the `UWaveGestureLibrary` UEA classification subset of
+[`thuml/Time-Series-Library`](https://huggingface.co/datasets/thuml/Time-Series-Library).
+
+## Overview
+
+Accelerometer traces of eight hand gestures; classify the gesture.
+
+- **Train samples:** 120  •  **Test samples:** 320.
+- **Dimensions (channels):** 3  •  **Series length:** 315.
+- **Classes:** 8.
+
+Each sample is an independent multivariate series. TRAIN and TEST are stored as
+two separate TsFiles (`UWaveGestureLibrary_train.tsfile` / `UWaveGestureLibrary_test.tsfile`).
+
+## Schema (TsFile structure)
+
+- **sample_index** (TAG) — one device per sample. Query one sample with
+  `WHERE sample_index=0`.
+- **Time** (INT64) — within-sample position (0..314); a frame index, not a
+  wall-clock timestamp (the sktime `.ts` source has none).
+- **dim_0 … dim_2** (FIELD, FLOAT) — the 3 channels at each position.
+- **class_label** (FIELD, STRING) — the sample's class, repeated on every row.
+
+Converted from the sktime `.ts` format. Nothing is dropped: every dimension,
+time point, and label is preserved.
+
+## Usage
+
+Read the `.tsfile` files with the Apache TsFile Java or Python SDK.
