英文摘要：
In this paper, we propose a modified Levy jump diffusion model with market sentiment memory for stock prices, where the market sentiment comes from data mining implementation using Tweets on Twitter. We take the market sentiment process, which has memory, as the signal of Levy jumps in the stock price. An online learning and optimization algorithm with the Unscented Kalman filter (UKF) is then proposed to learn the memory and to predict possible price jumps. Experiments show that the algorithm provides a relatively good performance in identifying asset return trends.

中文摘要：
在本文中，我们提出了一个改进的Levy跳跃扩散模型，该模型具有股票价格的市场情绪记忆，其中市场情绪来自使用推特上的推特实现的数据挖掘。我们将具有记忆的市场情绪过程作为利维跳升股价的信号。然后，提出了一种基于无迹卡尔曼滤波器（UKF）的在线学习和优化算法来学习记忆并预测可能的价格跳跃。实验表明，该算法在识别资产收益趋势方面具有较好的性能。
