The purpose of this paper is to explore machine learning techniques forecast the oil price. In era big data, we investigate whether new automated tools can improve over traditional approaches in terms accuracy. Oil price point and density forecasts are built from 23 methods, including regression trees (random forest, quantile xgboost), regularization procedures (elastic net, lasso, ridge), stan...
Recent empirical studies reveal evidence of the co-existence of heterogeneous data characteristics distinguishable by time scale in the movement crude oil prices. In this paper we propose a new multivariate Empirical Mode Decomposition (EMD)-based model to take advantage of these heterogeneous characteristics of the price movement and model them in the crude oil markets. Empirical studies in be...

One of the most used methods to forecast price volatility is the generalized autoregressive conditional heteroskedasticity (GARCH) model. Nonetheless, the errors in prediction using this approach are often quite high. Hence, continued research is conducted to improve forecasting models employing a variety of techniques. In this paper, we extend the field of expert systems, forecasting, and mode...
