However, the research about a comparison of different machine learning methods is rare; particularly, a comparison of the NN, Extreme Gradient Boosting (XGBoost3), and Light Gradient Boosting Machine (LightGBM4) lacks. A study about the latter two machine learning algorithms in petroleum engineering...
We compare different machine learning algorithms as surrogate models and exchange the grid topology and size. In a set of experiments, we show that algorithms based on linear regression and artificial neural networks yield the best results independent of the grid topology. Furthermore, adding ...
Supervised machine learning means we have examples (rows) with input and output variables (columns). We cannot write code to predict outputs given inputs because it is too hard, so we use machine learning algorithms to learn how to predict outputs from inputs given historical examples. This is...
Review of machine learning algorithms Many ML algorithms have been rapidly developed and applied over the past three decades, resulting in confusion about which model should be selected. Each algorithm has its own advantages and disadvantages and is developed for particular learning methods and applicati...
Types of Learning Given that the focus of the field of machine learning is “learning,” there are many types that you may encounter as a practitioner. Some types of learning describe whole subfields of study comprised of many different types of algorithms such as “supervised learning.” Others...
Machine Learning Models: We have tried boosted algorithms (XGBoost, LightGBM, Catboost) and fully connected neural network (FCNN) in this project. There are some technical differences in the application of different algorithms that needs to noticed: ...
causing a form of memory loss over the course of a sequence. In the previous example, the wordsis ithave a greater influence than the more meaningful worddate. Newer algorithms such as long short-term memory networksaddress this issueby using recurrent cells designed to preserve information over...
To avoid uncertainties, several studies have suggested using different machine learning algorithms and validating the predicted results in the lab (Englert et al., 2019; Saltzman and Yung, 2018; Yang et al., 2020).
