Neural-based Compression Scheme for Solar Image Data

Ali Zafari, Atefeh Khoshkhahtinat, Jeremy A. Grajeda +6

Studying the solar system and especially the Sun relies on the data gathered daily from space missions. These missions are data-intensive and compressing this data to make them eff…

Multi-spectral Entropy Constrained Neural Compression of Solar Imagery

Ali Zafari, Atefeh Khoshkhahtinat, Piyush M. Mehta +4

Missions studying the dynamic behaviour of the Sun are defined to capture multi-spectral images of the sun and transmit them to the ground station in a daily basis. To make transmi…

Frequency Disentangled Features in Neural Image Compression

Ali Zafari, Atefeh Khoshkhahtinat, Piyush Mehta +3

The design of a neural image compression network is governed by how well the entropy model matches the true distribution of the latent code. Apart from the model capacity, this abi…

Probabilistic Solar Proxy Forecasting with Neural Network Ensembles

Joshua D. Daniell, Piyush M. Mehta

Space weather indices are used commonly to drive forecasts of thermosphere density, which directly affects objects in low-Earth orbit (LEO) through atmospheric drag. One of the mos…
