Data-Driven and Theory-Guided Pseudo-Spectral Seismic Imaging Using Deep Neural Network Architectures
Christopher Zerafa
Full Waveform Inversion (FWI) reconstructs high-resolution subsurface models via multi-variate optimization but faces challenges with solver selection and data availability. Deep L…
Theory-guided Pseudo-spectral Full Waveform Inversion via Deep Neural Networks
Christopher Zerafa, Pauline Galea, Cristiana Sebu
Full-Waveform Inversion seeks to achieve a high-resolution model of the subsurface through the application of multi-variate optimization to the seismic inverse problem. Although no…
Data-Driven Pseudo-spectral Full Waveform Inversion via Deep Neural Networks
Christopher Zerafa, Pauline Galea, Cristiana Sebu
FWI seeks to achieve a high-resolution model of the subsurface through the application of multi-variate optimization to the seismic inverse problem. Although now a mature technolog…
Synergizing Deep Learning and Full-Waveform Inversion: Bridging Data-Driven and Theory-Guided Approaches for Enhanced Seismic Imaging
Christopher Zerafa, Pauline Galea, Cristiana Sebu
This review explores the integration of deep learning (DL) with full-waveform inversion (FWI) for enhanced seismic imaging and subsurface characterization. It covers FWI and DL fun…
A Simplified and Numerically Stable Approach to the BG/NBD Churn Prediction model
Dylan Zammit, Christopher Zerafa
This study extends the BG/NBD churn probability model, addressing its limitations in industries where customer behaviour is often influenced by seasonal events and possibly high pu…
