An explicit operator explains end-to-end computation in the modern neural networks used for sequence and language modeling
Anif N. Shikder, Ramit Dey, Sayantan Auddy +6
We establish a mathematical correspondence between state space models, a state-of-the-art architecture for capturing long-range dependencies in data, and an exactly solvable nonlin…
GRINN: A Physics-Informed Neural Network for solving hydrodynamic systems in the presence of self-gravity
Sayantan Auddy, Ramit Dey, Neal J. Turner +1
Modeling self-gravitating gas flows is essential to answering many fundamental questions in astrophysics. This spans many topics including planet-forming disks, star-forming clouds…
Spectrogram correlated stacking: A novel time-frequency domain analysis of the Stochastic Gravitational Wave Background
Ramit Dey, Luís Felipe Longo Micchi, Suvodip Mukherjee +1
The astrophysical stochastic gravitational wave background (SGWB) originates from numerous faint sub-threshold gravitational wave (GW) signals arising from the coalescing binary co…
Predicting Stellar Mass Accretion: An Optimized Echo State Network Approach in Time Series Modeling
Gianfranco Bino, Shantanu Basu, Ramit Dey +3
Modeling the dynamics of the formation and evolution of protostellar disks as well as the history of stellar mass accretion typically involve the numerical solution of complex syst…
Using Bayesian Deep Learning to infer Planet Mass from Gaps in Protoplanetary Disks
Sayantan Auddy, Ramit Dey, Min-Kai Lin +2
Planet induced sub-structures, like annular gaps, observed in dust emission from protoplanetary disks provide a unique probe to characterize unseen young planets. While deep learni…
Scalar perturbations around rotating regular black holes and wormholes: quasi-normal modes, ergoregion instability and superradiance
Edgardo Franzin, Stefano Liberati, Jacopo Mazza +2
We study scalar test-field perturbations on top of a Kerr--black-bounce background, i.e. a family of rotating regular black holes and/or rotating traversable wormholes that can mim…
