Special Issue Information

Dear Colleagues,

The application of statistical science to empirical finance has changed a great deal in the past ten years in response to technological advances and, in particular, to the development of machine learning methods. Financial markets are awash with big and complicated data, and researchers are trying to make sense out of it. Whereas traditionally scientists fit a few statistical models by hand, now they use sophisticated computational tools to search through a large number of models, looking for meaningful patterns and accurate predictions. Standard statistical methods for modelling financial data have been extended by machine learning models in many ways. Empirical finance models based on machine learning techniques now allow for more predictors than observations, incorporate non-linear relationships, accommodate interactions between predictors and, the presence of strong correlations. One of the main advantages of these novel models is the gain in predictive performance compared to standard statistical models and the ease of manipulation due to the availability of toolboxes and off-the-self routines that make their implementation straightforward even in large dimensions. The aim of this Special Issue is to obtain a deeper insight into these methods and their potential for applications in all fields of empirical finance.

This paper presents an overview of the procedures that are involved in prediction with machine learning models with special emphasis on deep learning. We study suitable objective functions for prediction in high-dimensional settings and discuss the role of regularization methods in order to alleviate the problem of overfitting. We also review other features of machine learning methods, such as the selection of hyperparameters, the role of the architecture of a deep neural network for model prediction, or the importance of using different optimization routines for model selection. The review also considers the issue of model uncertainty and presents state-of-the-art methods for constructing prediction intervals using ensemble methods, such as bootstrap and Monte Carlo dropout. These methods are illustrated in an out-of-sample empirical forecasting exercise that compares the performance of machine learning methods against conventional time series models for different financial indices. These results are confirmed in an asset allocation context. Full article
