Viewer and Loading
The standard repository layout enables the Hugging Face Dataset Viewer after processing. Load with the datasets library using hoangbang/hey-computer-speech-commands.
from datasets import load_dataset
dataset = load_dataset("hoangbang/hey-computer-speech-commands")
Preparation
- Tabular data is stored as Parquet.
- Image classification uses class directories and ImageFolder metadata.
- Object detection uses pixel-space COCO xywh metadata converted from YOLO annotations.
- Audio uses WAV folders and split metadata compatible with AudioFolder.
- ground_truth.csv, host_only, filename maps, source archives, and local OS files are excluded.
- The literal
__unlabeled__in the testlabelfield is a no-label sentinel, not an annotation.
