Clustering Time Series Using Dynamic Time Warping Distance in Provinces in Indonesia Based on Rice Prices

open access: yesTIERS Information Technology Journal, 2023
Rice is a food commodity that is a basic need for Indonesian people. Since the end of 2022, average rice prices in Indonesia have been increasing, breaking the record for the highest price from August to October 2023.

Graph-based two-level clustering for electric vehicle usage patterns

open access: yesEnergy and AI
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

Improved robustness in time series analysis of gene expression data by polynomial model based clustering [PDF]

open access: yes, 2006
Microarray experiments produce large data sets that often contain noise and considerable missing data. Typical clustering methods such as hierarchical clustering or partitional algorithms can often be adversely affected by such data.

A Fast Weighted Fuzzy C-Medoids Clustering for Time Series Data Based on P-Splines

open access: yesSensors, 2022
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

Guided conjugate Bayesian clustering for uncovering rhythmically expressed genes [PDF]

open access: yes, 2006
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

Advances in clustering and visualization of time series using GTM through time

open access: yes, 2008
Most of the existing research on multivariate time series concerns supervised forecasting problems. In comparison, little research has been devoted to their exploration through unsupervised clustering and visualization. In this paper, the capabilities of

Partial mixture model for tight clustering of gene expression time-course [PDF]

open access: yes, 2008
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.
