Detecting and explaining changes in various assets' relationships in financial markets

  title={Detecting and explaining changes in various assets' relationships in financial markets},
  author={Makoto Naraoka and Teruaki Hayashi and Yukio Ohsawa and Takaaki Yoshino and Toshiaki Sugie and Kota Takano},
We study the method for detecting relationship changes in financial markets and providing human-interpretable network visualization to support the decision-making of fund managers dealing with multi-assets. First, we construct co-occurrence networks with each asset as a node and a pair with a strong relationship in price change as an edge at each time step. Second, we calculate Graph-Based Entropy to represent the variety of price changes based on the network. Third, we apply the Differential… Expand

Experiments show that graph-based entropy outperforms baseline methods that can be used for change detection, in explaining substantial changes and their signs in consumers’ preference of items in supermarket stores. Expand
Dynamic programming algorithm optimization for spoken word recognition
This paper reports on an optimum dynamic progxamming (DP) based time-normalization algorithm for spoken word recognition, in which the warping function slope is restricted so as to improve discrimination between words in different categories. Expand
Time-Varying Differential Network Analysis for Revealing Network Rewiring over Cancer Progression
A new Gaussian graphical model-based method to jointly estimate multiple time-varying differential networks for identifying network rewiring over cancer development and rediscover well known genes associated with the development and progression of breast cancer is proposed. Expand

Unsupervised real-time anomaly detection for streaming data
A novel anomaly detection algorithm is proposed that is based on an online sequence memory algorithm called Hierarchical Temporal Memory (HTM) and presented using the Numenta Anomaly Benchmark (NAB), a benchmark containing real-world data streams with labeled anomalies. Expand
A survey of methods for time series change point detection
This survey article enumerates, categorizes, and compares many of the methods that have been proposed to detect change points in time series, and presents some grand challenges for the community to consider. Expand
