1. Data augmentation for deep
learning source separation of
HipHop songs
Universitat Pompeu Fabra, Barcelona, Music Technology Group
Hector Martel, Marius Miron
8. Datasets
Multi-track datasets with isolated instruments
DSD100 dataset
8
HipHop dataset
18 songs in the same production style (13/5)100 songs with different production styles (50/50)
Few, very similar songs
9. How do we avoid overfitting
- Regularization (l2 norm on weights)
- Dropouts
- Training data augmentation
13. Experiments
DSD100 HHDS
DSD - trained with DSD
DSD HH - trained with DSD and then HH
HH - trained with HHDS
DSD HH 2 - trained with DSD and then HH
HH COMBI - trained with HHDS
All augmentations
HH IA- trained with HHDS
Instrument augmentation

Circular shift augmentation
14. Evaluation metrics
SDR - Signal to Distortion Ratio
SIR - Signal to Interference Ratio
SAR - Signal to Artefacts Ratio
ISR - Image to Spatial distortion Ratio
