A new approach for optimal offline time-series segmentation with error bound guarantee
作者:
Highlights:
• An optimal offline time-series segmentation with error bound guarantee is proposed (OSFS method).
• The OSFS method is based on finding the shortest path in a directed graph.
• In order to reduce the computational time, the feasible space method (FS), proposed by Liu, is used.
• A new performance measure to evaluate the performance of heuristic and metaheuristic methods has also been proposed.
• These results demonstrate that the L-infinity norm produces better results than the L∞-norm.
