Abstract: The rapid growth of artificial intelligence (AI) technology and its applications in recent years have revolutionized the process of data analytics in many scientific fields, including geosciences. Geosciences has traditionally been a descriptive science and fundamentally relies upon visual recognition and identification of different geological features, from satellite images to subsurface seismic, to study Earth’s history. Geological image data provides the immense potential to apply advanced AI methods, such as deep convolutional neural network to improve and optimize different geological and geophysical characterization workflows. Despite the increasing efforts and interest toward implementing AI in various geosciences tasks, its actual potential remains untapped, and further exploration is required. In geosciences, the prospect of AI application is primarily hindered by the following: (i) limited availability of high-quality labeled datasets and (ii) inherited imbalance dataset distribution. These limitations are compounded by overexploitation of the transfer learning method to mitigate such issues, discarding the explainability of the AI black-box problems. Here, we aim to utilize and repurpose generative adversarial networks to overcome such challenges by providing (i) a way to significantly increase the number of high-quality labelled dataset and (ii) a novel workflow for self-supervised and weakly-supervised image classification and segmentation in geosciences.
