Stored time series data sequences have been applied to various services up to now. An importance of the processing technology of the streaming time series data streams will be rising because of the miniaturization and the price cutting of sensors in the future. In this work, we challenged the problem of monitoring time series data streams to detect similarity in high-speed and exact accuracy. We propose dividing method for multi-dimensional space and dimensionality reduction method from which it is guaranteed that the distance becomes more or equal after dimensionality reduction than before. We verified that our methods are efficient in speed than previous method by evaluating in trajectory data streams in certain condition. |
