Recent Techniques of Clustering of Time Series Data: A Survey Time-Series clustering is one of the important concepts of data mining that is used to gain insight into the mechanism that generate the time-series and predicting the future values of the given time-series. Time-series data are fr...

Survey Methodology 1 Introduction In data mining, several analysis tasks are used to extract useful and hidden information from raw data. One of the most important tasks is anomaly detection which is crucial to many real applications. Identifying anomalous instances in a dataset can lead to discover...
They are computationally demanding if all 2n − 1 − 1 possible divisions of a cluster of n examples into two sub-clusters are considered in each step. However, for data consisting solely of binary attributes, relatively simple and computationally effective monothetic divisive methods are ...
of bedrock fault scarps (Figs.4and5)14. The data confirm the slip-rates and strain-rates averaged over 15 ± 3 ka in Fig.1, but reveal periods of rapid slip on some faults, with up to 15 m of slip in as little as 3500 years, that are contemporaneous with periods of low...
Driving cycle varies with data collection technique. Chase car technique and onboard measurement technique are the most commonly used methods of data collection. In chase car method, the target vehicle is followed externally to collect speed time data, whereas in on-board measurement technique an ...
