英文摘要：
We propose the application of a high-speed maximum likelihood clustering algorithm to detect temporal financial market states, using correlation matrices estimated from intraday market microstructure features. We first determine the ex-ante intraday temporal cluster configurations to identify market states, and then study the identified temporal state features to extract state signature vectors which enable online state detection. The state signature vectors serve as low-dimensional state descriptors which can be used in learning algorithms for optimal planning in the high-frequency trading domain. We present a feasible scheme for real-time intraday state detection from streaming market data feeds. This study identifies an interesting hierarchy of system behaviour which motivates the need for time-scale-specific state space reduction for participating agents.

中文摘要：
我们提出了一种利用日内市场微观结构特征估计相关矩阵的高速最大似然聚类算法来检测暂时性金融市场状态。我们首先确定事前的日内时间集群配置来识别市场状态，然后研究已识别的时间状态特征来提取状态特征向量，从而实现在线状态检测。状态特征向量作为低维状态描述符，可用于高频交易领域的最优规划学习算法。我们提出了一种从流媒体市场数据源中实时检测日内状态的可行方案。这项研究确定了一个有趣的系统行为层次结构，它促使参与代理需要时间尺度特定的状态空间缩减。
