Interleaved Noise Injection Improves Clean, Corrupted, and OOD Performance
Matt L. Wiemann, Peter Melchior, Andrew K. Saydjari
Noise injection is a well-known technique in stochastic optimization. We report its surprising effectiveness with an interleaved (on-off-on-off...) rather than the usual monotonic…
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…
