In training a deep learning system to perform audio transcription, two practical problems may arise.

A Generative Model for Natural Sounds Based on Latent Force Modelling

no code implementations2 Feb 2018 William J. Wilkinson, Joshua D. Reiss, Dan Stowell

Recent advances in analysis of subband amplitude envelopes of natural sounds have resulted in convincing synthesis, showing subband amplitudes to be a crucial component of perception.

Efficient Learning of Harmonic Priors for Pitch Detection in Polyphonic Music

1 code implementation19 May 2017 Pablo A. Alvarado, Dan Stowell

Automatic music transcription (AMT) aims to infer a latent symbolic representation of a piece of music (piano-roll), given a corresponding observed audio recording.

Denoising without access to clean data using a partitioned autoencoder

no code implementations20 Sep 2015 Dan Stowell, Richard E. Turner

Training a denoising autoencoder neural network requires access to truly clean data, a requirement which is often impractical.


Acoustic Scene Classification

Automatic large-scale classification of bird sounds is strongly improved by unsupervised feature learning

no code implementations26 May 2014 Dan Stowell, Mark D. Plumbley

Feature learning can be performed at large scale and "unsupervised", meaning it requires no manual data labelling, yet it can improve performance on "supervised" tasks such as classification.
