Latent Diffusion Model for Conditional Reservoir Facies Generation

no code implementations3 Nov 2023 Daesoo Lee, Oscar Ovanger, Jo Eidsvik, Erlend Aune, Jacob Skauvold, Ragnar Hauge

Creating accurate and geologically realistic reservoir facies based on limited measurements is crucial for field development and reservoir management, especially in the oil and gas sector.

Masked Generative Modeling with Enhanced Sampling Scheme

1 code implementation14 Sep 2023 Daesoo Lee, Erlend Aune, Sara Malacarne

ESS explicitly ensures both sample diversity and fidelity, and consists of three stages: Naive Iterative Decoding, Critical Reverse Sampling, and Critical Resampling.

VNIbCReg: VICReg with Neighboring-Invariance and better-Covariance Evaluated on Non-stationary Seismic Signal Time Series

1 code implementation6 Apr 2022 Daesoo Lee, Erlend Aune, Nadège Langet, Jo Eidsvik

This study shows that a combination of a VICReg-style method and TNC is very effective for SSL on non-stationary time series, where a non-stationary seismic signal time series is used as an evaluation dataset.

Computer Vision Self-supervised Learning Methods on Time Series

1 code implementation2 Sep 2021 Daesoo Lee, Erlend Aune

Our method improves on a \textit{covariance} term proposed in VICReg, and in addition we augment the head of the architecture by an iterative normalization layer that accelerates the convergence of the model.

Augmented Memory Networks for Streaming-Based Active One-Shot Learning

no code implementations4 Sep 2019 Andreas Kvistad, Massimiliano Ruocco, Eliezer de Souza da Silva, Erlend Aune

In stream-based AL, observations are continuously made available to the learner that have to decide whether to request a label or to make a prediction.
