Continuous Monitoring of Blood Pressure with Evidential Regression

no code implementations6 Feb 2021 Hyeongju Kim, Woo Hyun Kang, Hyeonseung Lee, Nam Soo Kim

Photoplethysmogram (PPG) signal-based blood pressure (BP) estimation is a promising candidate for modern BP measurements, as PPG signals can be easily obtained from wearable devices in a non-invasive manner, allowing quick BP measurement.


Unsupervised Representation Learning for Speaker Recognition via Contrastive Equilibrium Learning

1 code implementation22 Oct 2020 Sung Hwan Mun, Woo Hyun Kang, Min Hyun Han, Nam Soo Kim

In this paper, we propose a simple but powerful unsupervised learning method for speaker recognition, namely Contrastive Equilibrium Learning (CEL), which increases the uncertainty on nuisance factors latent in the embeddings by employing the uniformity loss.
