英文摘要：
Nowadays, with the availability of massive amount of trade data collected, the dynamics of the financial markets pose both a challenge and an opportunity for high frequency traders. In order to take advantage of the rapid, subtle movement of assets in High Frequency Trading (HFT), an automatic algorithm to analyze and detect patterns of price change based on transaction records must be available. The multichannel, time-series representation of financial data naturally suggests tensor-based learning algorithms. In this work, we investigate the effectiveness of two multilinear methods for the mid-price prediction problem against other existing methods. The experiments in a large scale dataset which contains more than 4 millions limit orders show that by utilizing tensor representation, multilinear models outperform vector-based approaches and other competing ones.

中文摘要：
如今，随着收集到的大量贸易数据的可用性，金融市场的动态对高频交易者既是挑战也是机遇。为了利用高频交易（HFT）中资产的快速、细微移动，必须提供一种基于交易记录分析和检测价格变化模式的自动算法。金融数据的多通道时间序列表示自然建议使用基于张量的学习算法。在这项工作中，我们研究了两种多线性方法对中间价格预测问题的有效性。在一个包含400多万个极限阶的大规模数据集上的实验表明，通过使用张量表示，多线性模型的性能优于基于向量的方法和其他竞争方法。
