An Visualization of hierarchical time series data with Heiankyo View

Visualization of multi-dimensional data of bioactive chemicals using a hierarchical data visualization technique "Heiankyo view"

In the age of combinatorial chemistry and high throughput screening, large-scale data of bioactive chemicals oriented to drug development are being accumulated. Due to the difficulties inherent in understanding such large quantities of data, information visualization techniques are increasingly attractive. Authors apply “HeiankyoView”, which is the technique for the representation of large-scal...

A Visualization Technique for Hierarchical Time Series Task Data

This paper presents an information visualization technique that represents both time series information and hierarchical structure onto a two-dimensional display space. It represents time series data as bar charts along the horizontal axis of a screen, and hierarchical structure as nested rectangular borders enclosing the bar charts. It packs the nested rectangular borders representing hierarch...

Hierarchical Time-Series Clustering for Data Streams⋆

This paper presents a time-series whole clustering system that incrementally constructs a hierarchy of clusters. The Online DivisiveAgglomerative Clustering (ODAC) system is an incremental implementation of divisive analysis clustering, using the correlation between timeseries as similarity measure. The system tests existing clusters by descending order of diameters, looking for a possible bina...

Improved Hierarchical Clustering Using Time Series Data

Mining Time series data has a remarkable development of interest in today’s world. This paper presents and evaluates an incremental clustering structure for time series data stream. The new algorithm is called Improved Hierarchical Clustering Algorithm (IHCA) is developed and applied with ECG data set. This system continuously constructs a tree structure of hierarchy that progress with data set...
