LSTM能胜过波动计量经济模型吗?

Can LSTM outperform volatility-econometric models?

German Rodikov, Nino Antulov-Fantulin

摘要:

金融资产波动率预测是理解金融风险和二次价格变动的基本问题之一。然而,尽管最近提出了许多新颖的深度学习模型,但它们仍然“很难”超越强计量经济学波动率模型。为什么会这样呢?由于噪声、市场微观结构、异方差性、新闻的外生和非对称效应以及不同时间尺度的存在,波动率预测任务具有非平凡的复杂性。在本文中,我们分析了用于波动率预测任务的长短期记忆(LSTM)递归神经网络,并将其与强波动率计量经济模型进行了比较。

英文摘要:

Volatility prediction for financial assets is one of the essential questions for understanding financial risks and quadratic price variation. However, although many novel deep learning models were recently proposed, they still have a "hard time" surpassing strong econometric volatility models. Why is this the case? The volatility prediction task is of non-trivial complexity due to noise, market microstructure, heteroscedasticity, exogenous and asymmetric effect of news, and the presence of different time scales, among others. In this paper, we analyze the class of long short-term memory (LSTM) recurrent neural networks for the task of volatility prediction and compare it with strong volatility-econometric models.
