Proximity Forest 2.0: A new effective and scalable similarity-based classifier for time series

1 code implementation12 Apr 2023 Matthieu Herrmann, Chang Wei Tan, Mahsa Salehi, Geoffrey I. Webb

Time series classification (TSC) is a challenging task due to the diversity of types of feature that may be relevant for different classification tasks, including trends, variance, frequency, magnitude, and various patterns.

Dynamic Time Warping Time Series +1

Early Abandoning and Pruning for Elastic Distances including Dynamic Time Warping

2 code implementations10 Feb 2021 Matthieu Herrmann, Geoffrey I. Webb

This threshold, provided by the similarity search process, also allows to early abandon the computation of a distance itself.

Early Abandoning PrunedDTW and its application to similarity search

1 code implementation11 Oct 2020 Matthieu Herrmann, Geoffrey I. Webb

We show that EAPrunedDTW significantly improves the computation time of similarity search in the UCR Suite, and renders lower bounds dispensable.
