A novel approach to classification of ECG arrhythmia types with latent ODEs
Angelina Yan, Matt L. Sampson, Peter Melchior
12-lead ECGs with high sampling frequency are the clinical gold standard for arrhythmia detection, but their short-term, spot-check nature often misses intermittent events. Wearabl…
Optimization as a Dynamical System: Generative Schedules from Latent ODEs
Matt L. Sampson, Peter Melchior
We present a new meta-learning method to determine the optimal learning rate schedule for gradient descent. It leverages training runs from a hyperparameter search to learn a laten…
Disentangling transients and their host galaxies with Scarlet2: A framework to forward model multi-epoch imaging
Charlotte Ward, Peter Melchior, Matt L. Sampson +6
Many science cases for wide-field time-domain surveys rely on accurate identification and characterization of the galaxies hosting transient and variable objects. In the era of the…
Path-minimizing Latent ODEs for improved extrapolation and inference
Matt L. Sampson, Peter Melchior
Latent ODE models provide flexible descriptions of dynamic systems, but they can struggle with extrapolation and predicting complicated non-linear dynamics. The latent ODE approach…
