Search Dimension in Unlabeled Projection Pursuit: A Scaling Law for Subspace Restriction
Rares Dimitrie Grozavescu, Mark Girolami
Projection pursuit searches for a direction along which the data look least Gaussian. When the observation space contains a large Gaussian complement, the empirical objective can b…

Towards Efficient and Stable Ocean State Forecasting: A Continuous-Time Koopman Approach
Rares Grozavescu, Pengyu Zhang, Mark Girolami +1
We investigate the Continuous-Time Koopman Autoencoder (CT-KAE) as a lightweight surrogate model for long-horizon ocean state forecasting in a two-layer quasi-geostrophic (QG) syst…

Invertible continuous latent dynamic for long-term data assimilation in complex physical systems
Rares Grozavescu, Pengyu Zhang, Etienne Meunier +1
Forward forecasting and data assimilation are the two important aspects in physical simulation: one propagates the state forward, the other recovers unknown states from sparse obse…
