PaPaGei: Open Foundation Models for Optical Physiological Signals

ICLR 2025poster

Photoplethysmography (PPG) is the leading non-invasive technique for monitoring biosignals and cardiovascular health, with widespread adoption in both clinical settings and consumer wearable devices. While machine learning models trained on PPG signals have shown promise, they tend to be task-specif…

SoundCollage: Automated Discovery of New Classes in Audio Datasets

ICASSP 2025accepted

Developing new machine learning applications often requires the collection of new datasets. However, existing datasets may already contain relevant information to train models for new purposes. We propose SoundCollage: a framework to discover new classes within audio datasets by incorporating (1) an…

COVID-19 Sounds: A Large-Scale Audio Dataset for Digital Respiratory Screening

NeurIPS 2021poster

Audio signals are widely recognised as powerful indicators of overall health status, and there has been increasing interest in leveraging sound for affordable COVID-19 screening through machine learning. However, there has also been scepticism regarding the initial efforts, due to perhaps the lack o…

Exploring Automatic COVID-19 Diagnosis via Voice and Symptoms from Crowdsourced Data

ICASSP 2021accepted

The development of fast and accurate screening tools, which could facilitate testing and prevent more costly clinical tests, is key to the current pandemic of COVID-19. In this context, some initial work shows promise in detecting diagnostic signals of COVID-19 from audio sounds. In this paper, we p…
