Evaluation of k-means time series clustering based on z-normalization and NP-Free

no code implementations28 Jan 2024 Ming-Chang Lee, Jia-Chun Lin, Volker Stolz

By systematically investigating the performance of k-means time series clustering with these two normalization techniques, this paper addresses the current gap in k-means time series clustering evaluation and contributes valuable insights to the development of time series clustering.

NP-Free: A Real-Time Normalization-free and Parameter-tuning-free Representation Approach for Open-ended Time Series

no code implementations12 Apr 2023 Ming-Chang Lee, Jia-Chun Lin, Volker Stolz

Without needing to use any normalization method or tune any parameter, NP-Free can generate a representation for a raw time series on the fly by converting each data point of the time series into a root-mean-square error (RMSE) value based on Long Short-Term Memory (LSTM) and a Look-Back and Predict-Forward strategy.
