# ASL Keypoint Dataset - 84 Classes

This dataset contains preprocessed MediaPipe Holistic keypoint sequences for isolated sign language classification.

## Dataset Version

This version keeps only classes with at least 50 training samples. In your current filtered version, this produced 84 classes.

## Files

- `train_features_50plus.npy`
- `train_labels_50plus.npy`
- `val_features_50plus.npy`
- `val_labels_50plus.npy`
- `id_to_label_50plus.json`
- `label_to_id_50plus.json`
- `old_to_new_label_ids_50plus.json`
- `new_to_old_label_ids_50plus.json`
- `class_counts_after_filtering_50plus.csv`
- `filter_metadata_50plus.json`

## Important Note

The label IDs have been remapped after filtering. During inference, use `id_to_label_50plus.json` to convert model output IDs back to sign labels.
