Adversarial Autoencoders in Operator Learning

Autor: Enyeart, Dustin, Lin, Guang

DeepONets and Koopman autoencoders are two prevalent neural operator architectures. These architectures are autoencoders. An adversarial addition to an autoencoder have improved performance of autoencoders in various areas of machine learning. In thi

Loss Terms and Operator Forms of Koopman Autoencoders

Autor: Enyeart, Dustin, Lin, Guang

Koopman autoencoders are a prevalent architecture in operator learning. But, the loss functions and the form of the operator vary significantly in the literature. This paper presents a fair and systemic study of these options. Furthermore, it introdu

Evidence has emerged for a stochastic signal correlated among 67 pulsars within the 15-year pulsar-timing data set compiled by the NANOGrav collaboration. Similar signals have been found in data from the European, Indian, Parkes, and Chinese PTAs. Th

A Time-Dependent Spectral Analysis of $\gamma$ Cassiopeiae

Autor: Gunderson, Sean J., Huenemoerder, David P., Torrejón, José M., Swarm, Dustin K., Nichols, Joy S., Pradhan, Pragati, Ignace, Richard, Guenther, Hans Moritz, Pollock, A. M. T., Schulz, Norbert S.

We investigated the temporal and spectral features of $\gamma$ Cassiopeiae's X-ray emission within the context of the white dwarf accretion hypothesis. We find that the variabilities present in the X-ray data show two different signals, one primarily

We propose to measure the beam normal single spin asymmetry in elastic scattering of transversely polarized electron from target nuclei with 12 $\leq Z \leq$ 90 at Q$^2$ = 0.0092 GeV$^2$ to study its nuclear dependence. While the theoretical calculat
