Using Permutations for Hierarchical Clustering of Time Series

open access: yesEntropy, 2019
Two distances based on permutations are considered to measure the similarity of two time series according to their strength of dependency. The distance measures are used together with different linkages to get hierarchical clustering methods of time ...

Topic Network Analysis Based on Co-Occurrence Time Series Clustering

open access: yesMathematics, 2022
Traditional topic research divides similar topics into the same cluster according to clustering or classification from the perspective of users, which ignores the deep relationship within and between topics. In this paper, topic analysis is achieved from

Time Series Clustering Method Based on Contrastive Learning [PDF]

open access: yesJisuanji kexue
It is difficult to intuitively define the similarity between time series by deep clustering methods which rely heavily on complex feature extraction networks and clustering algorithms.Contrastive learning can define the interval similarity of time series
