Window Size Selection in Unsupervised Time Series Analytics: A Review and Benchmark

2 code implementations Advanced Analytics and Learning on Temporal Data 2023 Arik Ermshaus, Patrick Schäfer, Ulf Leser

We provide, for the first time, a systematic survey and experimental study of 6 TS window size selection (WSS) algorithms on three diverse TSDM tasks, namely anomaly detection, segmentation and motif discovery, using state-of-the art TSDM algorithms and benchmarks.

ClaSP -- Parameter-free Time Series Segmentation

2 code implementations28 Jul 2022 Arik Ermshaus, Patrick Schäfer, Ulf Leser

Such processes often consist of multiple states, e. g. operating modes of a machine, such that state changes in the observed processes result in changes in the distribution of shape of the measured values.

ClaSP - Time Series Segmentation

2 code implementations International Conference on Information & Knowledge Management 2021 Patrick Schäfer, Arik Ermshaus, Ulf Leser

In our experimental evaluation using a benchmark of 98 datasets, we show that ClaSP outperforms the state-of-the-art in terms of accuracy and is also faster than the second best method.
