Dataset Card for VocSim - Mouse Identity Classification

Dataset Description

This dataset is used in the VocSim benchmark paper for evaluating the ability of neural audio embeddings to identify individual mice based on their ultrasonic vocalization (USV) syllables. It contains pre-segmented USV syllables from multiple individual mice, derived from recordings created by Van Segbroeck et al. (2017).

The primary task associated with this dataset is supervised classification: training a model to predict the correct mouse identity (speaker field) given an audio input (a single syllable) or its derived features.

Included Files:

Hugging Face Dataset object containing audio file paths (individual syllables) and metadata (mouse identity).

Dataset Structure

Data Instances

A typical example in the dataset looks like this:

{
  'audio': {'path': '/path/to/datasets/mouse_identity/BM003/BM003_syllable_1.wav', 'array': array([...], dtype=float32), 'sampling_rate': 250000},
  'subset': 'mouse_identity',
  'index': 50,
  'speaker': 'BM003', # The crucial individual mouse ID (target label)
  'label': 'BM003_syllable_1', # Syllable-specific identifier
  'original_name': 'BM003/BM003_syllable_1.wav' # Example original relative path
}
