- W3126968968 abstract "Machine learning has been a popular option implied volatility pricing approach. It brings a good generalization in pricing by avoiding building different models for different options. However, it suffers from a relatively low prediction accuracy besides a model selection issue. In this study, we propose a novel hierarchical learning approach to enhance machine learning implied volatility pricing. It is designed for the ‘learning-hard’ problem and boosts different machine learning models’ performance for different option data on behalf of moneyness besides identifying the optimal learning models. In particular, the proposed hierarchical learning can be an excellent way to enhance implied volatility pricing for the option datasets with more noise. In addition, we find out-of-the-money options fit machine learning prediction better than the other options. This pioneering study provides a robust way to enhance implied volatility pricing via machine learning and will inspire similar studies in the future." @default.
