Clustering of streaming time series is meaningless [PDF]
Time series data is perhaps the most frequently encountered type of data examined by the data mining community. Clustering is perhaps the most frequently used data mining algorithm, being useful in it's own right as an exploratory technique, and also as a subroutine in more complex data mining algorithms such as rule discovery, indexing, summarization,

A Fast Weighted Fuzzy C-Medoids Clustering for Time Series Data Based on P-Splines
The rapid growth of digital information has produced massive amounts of time series data on rich features and most time series data are noisy and contain some outlier samples, which leads to a decline in the clustering effect. To efficiently discover the

Special Issue on ‘Time series clustering’ [PDF]
There exists a great variety of clustering methods for multidimensional data points or dissimilarity data, they are standard tools in many statistical packages or data mining systems. More complex data types require special approaches, either by a reduction to classical cases by suitable preprocessing steps, by specifying appropriate dissimilarity ...

Graph-based two-level clustering for electric vehicle usage patterns
Electric vehicles (EVs) continue to gain popularity over internal combustion vehicles, but driving and charging an EV is a fundamentally different experience. EV usage patterns include features such as charging speed, battery state of charge, and battery

In-Database Time Series Clustering
Time series data are often clustered repeatedly across various time ranges to mine frequent subsequence patterns from different periods, which could further support downstream applications. Existing state-of-the-art (SOTA) time series clustering method, such as K-Shape, can proficiently cluster time series data referring to their shapes.

Partial mixture model for tight clustering of gene expression time-course [PDF]
Background: Tight clustering arose recently from a desire to obtain tighter and potentially more informative clusters in gene expression studies. Scattered genes with relatively loose correlations should be excluded from the clusters.

Time Series Clustering Based on Singularity [PDF]
With relevant theories on time series clustering, the thesis makes research into similarity clustering process of time series from the perspective of singularity and proposes the time series clustering based on singularity applying K-means and DBScan ...

Multivariate Time Series Density Clustering Algorithm Using Shapelet Space [PDF]
Multivariate time series clustering has become an important research topic in the task of time series analysis. Compared with univariate time series, the research of multivariate time series is more complex and difficult.

Guided conjugate Bayesian clustering for uncovering rhythmically expressed genes [PDF]
Background: An increasing number of microarray experiments produce time series of expression levels for many genes. Some recent clustering algorithms respect the time ordering of the data and are, importantly, extremely fast. The focus of this paper is
