Time-Series, Domain-Theory . 0000017668 00000 n For example, suppose that you get a correlation of value C12 between time-series 1 and 2. Examples of time series are heights of ocean tides, counts of sunspots, and the daily closing value of the Dow Jones Industrial Average. The following diagram shows an example of a time series data mining model that was created with the default settings, to create a mixed model. 0000017896 00000 n EEG (electroencephalogram) recordings. In fact, the goal of the analysis is to discover the correct model even if it is not correct. Time series data is data in a series of particular time intervals or periods. Descriptive data mining tasks usually finds data describing patterns and comes up with new, significant information from the available data set. Thus it is a sequence of discrete-time data. . Most time series data mining algorithms use similarity search as a core subroutine, and thus the time taken for similarity search is the bottleneck for virtually all time series data mining . Data mining also enables healthcare insurers to recognize fraud and abuse.

Different prediction and classification data mining tasks actually extract the required information from the available data sets. Time series data has a natural temporal ordering this differs from typical data mining/machinelearning applications where each data point is an independent example of the concept to be learned,and the ordering of data points within a data set does not matter. The data mining tasks can be classified generally into two types based on what a specific task tries to achieve. All these tasks are either predictive data mining tasks or descriptive data mining tasks.
