Virtual receiver functions via conditional diffusion transformers for robust crustal imaging
Tiente R. Koireng, Priyanshu Gupta, Pawan Bharadwaj
Receiver functions (RFs) are widely used to image crustal and upper-mantle structure, and their variation with backazimuth and epicentral distance contains key information about la…
Cold-Diffusion Driven Downward Continuation of Gravity Data
Adarsh Jain, Pawan Bharadwaj, Chandra Sekhar Seelamantula
Gravity data can be better interpreted after enhancing high-frequency information via downward continuation. Downward continuation is an ill-posed deconvolution problem. It has bee…
Enhanced receiver function imaging of crustal structures using symmetric autoencoders
T. Rengneichuong Koireng, Pawan Bharadwaj
The receiver-function (RF) technique aims to recover receiver-side crustal and mantle structures by deconvolving either the radial or transverse component with the vertical compone…
Coherent Spectral Feature Extraction Using Symmetric Autoencoders
Archisman Bhattacharjee, Pawan Bharadwaj
Hyperspectral data acquired through remote sensing are invaluable for environmental and resource studies. While rich in spectral information, various complexities such as environme…
On extracting coherent seismic wavefield using variational symmetric autoencoders
Pawan Bharadwaj
We discuss the variational formulation of the Symmetric Autoencoder (SymAE) and its role in achieving disentanglement within the latent space to extract coherent information from a…
