有许多根据时间扭曲(time warp)和编辑距离(edit distance)的弹性度量方法提出。 因此第一个目标是为了统计这些方法是否真的显著比DTW好。作者在introduction直接给出答案。No 有上述的问题,leading us to the question, 我们是否需要只要用DTW就可以了,不需要更复杂的度量方法?

In Chapter 3, a new test of hypotheses for classifying stationary time series based on bias-adjusted estimators of fitted autoregressive model is proposed. In the literature, many of the existing classification methods may achieve poor performance when dealing with relatively short time series, and ...
Most methods for time series classification that attain state-of-the-art accuracy have high computational complexity, requiring significant training time even for smaller datasets, and are intractable for larger datasets. 6 Paper Code A Transformer-based Framework for Multivariate Time Series Representati...
