Abstract

Earth Scientists have used machine learning for at least three decades and the applications span is large, from remote sensing to analysis of well log data, among many others. Although machine learning is becoming more popular in different fields of Earth Sciences, some concepts of convolutional neural networks may be vaguely understood by non-practitioners. In this presentation, I show some of the key concepts on the foundations of convolutional neural networks, some techniques that can help us understand them, and strategies that can be used to train these types of models. The objective of the presentation is not to focus on mathematical and implementation details, but to help build the intuition necessary to use and analyze the outputs of convolutional neural network models. The case studies include microfossil classification and core lithofacies classification, both using colored photographs. The final case study shows how convolutional neural networks can be used for sea ice segmentation using synthetic aperture radar.
