摘要:

我们研究了多目标深度强化学习在股票和加密货币单一资产交易中的潜力:特别是,我们考虑了一种多目标算法,该算法概括了奖励函数和折扣因子(即,这些分量不是先验指定的,而是结合在学习过程中)。首先,使用几种重要的资产(加密货币对BTCUSD,ETHUSDT,XRPUSDT和股票指数AAPL,SPY,NIFTY50),我们验证了所提出的多目标算法的奖励泛化特性,并提供了初步的统计证据,表明与相应的单目标策略相比,预测稳定性有所提高。其次,我们证明了当奖励机制是稀疏的(即,当非零反馈随时间不频繁时)。最后,我们讨论了关于折扣因子的推广性质。我们的代码全部以开源格式提供。

英文摘要:

We investigate the potential of Multi-Objective, Deep Reinforcement Learning for stock and cryptocurrency single-asset trading: in particular, we consider a Multi-Objective algorithm which generalizes the reward functions and discount factor (i.e., these components are not specified a priori, but incorporated in the learning process). Firstly, using several important assets (cryptocurrency pairs BTCUSD, ETHUSDT, XRPUSDT, and stock indexes AAPL, SPY, NIFTY50), we verify the reward generalization property of the proposed Multi-Objective algorithm, and provide preliminary statistical evidence showing increased predictive stability over the corresponding Single-Objective strategy. Secondly, we show that the Multi-Objective algorithm has a clear edge over the corresponding Single-Objective strategy when the reward mechanism is sparse (i.e., when non-null feedback is infrequent over time). Finally, we discuss the generalization properties with respect to the discount factor. The entirety of our code is provided in open source format.
