Discovering shapelets with key points in time series classification

作者：

Highlights：

• A new method is proposed to detect key points in the time series.

• Extracting shapelets based on key points and pruning redundant shapelets.

• Experiments on real datasets verify effectiveness and efficiency of our proposal.
