英文摘要：
  In this paper we develop a novel neural network model for predicting implied volatility surface. Prior financial domain knowledge is taken into account. A new activation function that incorporates volatility smile is proposed, which is used for the hidden nodes that process the underlying asset price. In addition, financial conditions, such as the absence of arbitrage, the boundaries and the asymptotic slope, are embedded into the loss function. This is one of the very first studies which discuss a methodological framework that incorporates prior financial domain knowledge into neural network architecture design and model training. The proposed model outperforms the benchmarked models with the option data on the S&P 500 index over 20 years. More importantly, the domain knowledge is satisfied empirically, showing the model is consistent with the existing financial theories and conditions related to implied volatility surface.

中文摘要：
本文提出了一种新的神经网络模型来预测隐含波动率面。考虑到先前的金融领域知识。提出了一种新的包含波动率微笑的激活函数，用于处理标的资产价格的隐藏节点。此外，财务状况，如无套利、边界和渐近斜率，都嵌入到损失函数中。这是最早讨论将先前金融领域知识纳入神经网络架构设计和模型训练的方法框架的研究之一。在标普500指数20年的期权数据中，拟议模型的表现优于基准模型。更重要的是，领域知识在经验上得到了满足，表明该模型与现有的金融理论和与隐含波动率面相关的条件是一致的。
