When is Early Classification of Time Series Meaningful?
In this work, we make a surprising claim. In spite of the fact that there are dozens of papers on early classification of time series, none of them could ever work in a real-world setting.

Current Time Series Anomaly Detection Benchmarks are Flawed and are Creating the Illusion of Progress
In this work, we make a surprising claim. The majority of the individual exemplars in datasets created by Yahoo, Numenta, NASA, etc., suffer from one or more of four flaws.
FastDTW is approximate and Generally Slower than the Algorithm it Approximates
In this work, we make a surprising claim. In any realistic data mining application, the approximate FastDTW is orders of magnitude slower than the exact DTW.
