Coresets for Time Series Clustering [PDF]

open access: yesSSRN Electronic Journal, 2021
We study the problem of constructing coresets for clustering problems with time series data. This problem has gained importance across many fields including biology, medicine, and economics due to the proliferation of sensors facilitating real-time measurement and rapid drop in storage costs. In particular, we consider the setting where the time series

Measuring Extremal Clustering in Time Series

open access: yesEngineering Proceedings, 2023
The propensity of data to cluster at extreme values is important for risk assessment. For example, heavy rain over time leads to catastrophic floods. The extremal index is a measure of Extreme Values Theory that allows measurement of the degree of high ...

Clustering discrete-valued time series [PDF]

open access: yesAdvances in Data Analysis and Classification, 2020
There is a need for the development of models that are able to account for discreteness in data, along with its time series properties and correlation. Our focus falls on INteger-valued AutoRegressive (INAR) type models. The INAR type models can be used in conjunction with existing model-based clustering techniques to cluster discrete-valued time ...

Clustering time series based on dependence structure. [PDF]

open access: yesPLoS ONE, 2018
The clustering of time series has attracted growing research interest in recent years. The most popular clustering methods assume that the time series are only linearly dependent but this assumption usually fails in practice. To overcome this limitation,

Time series clustering of COVID-19 pandemic-related data

open access: yesData Science and Management, 2023
The COVID-19 pandemic continues to impact daily life worldwide. It would be helpful and valuable if we could obtain valid information from the COVID-19 pandemic sequential data itself for characterizing the pandemic.

Satellite Image Time Series Clustering via Time Adaptive Optimal Transport

open access: yesRemote Sensing, 2021
Satellite Image Time Series (SITS) have become more accessible in recent years and SITS analysis has attracted increasing research interest. Given that labeled SITS training samples are time and effort consuming to acquire, clustering or unsupervised ...

Efficient Time Series Clustering by Minimizing Dynamic Time Warping Utilization

open access: yesIEEE Access, 2021
Dynamic Time Warping (DTW) is a widely used distance measurement in time series clustering. DTW distance is invariant to time series phase perturbations but has a quadratic complexity.

Dynamic Matrix Clustering Method for Time Series Events

open access: yesJisuanji kexue yu tansuo, 2021
Time series events clustering is the basis of studying the classification of events and mining analysis. Most of the existing clustering methods directly aim at continuous events with time attribute and complex structure, but the transformation of ...
