Describe:


Adding the time dimension to the real world databases produces TimeSeries databases (TSDB), introduces new and more difficult aspects of data mining and knowledge discovery. This book covers the most recent methodology for mining time series databases. Methods for extracting the thienophil data presented in the book include effective classification, indexing, and loud and dynamic time series classification techniques. An abbreviated intime series graph method for anomaly detection has been described, and the book studies the implications of a possible new and useful representation of the time series series. The problem of detecting changes in data mining forms that occur from time databases is discussed in addition

Introduction


Traditional data mining methods are designed to handle "static" Databases, i.e. databases where records are arranged (or other database) Things) have nothing to do with patterns of interest. 
Although the assumption that the order may not be significant may be accurate enough in some applications, There are definitely many other cases where serial information is like The time stamp associated with each record can be greatly enhanced Knowledge about mined data.
 One example is a series of stock values:
The specific closing price recorded yesterday has a completely different meaning to the same value a year ago. Since most databases are today Include time data in the form of "creation date" and "modification date" and Other time-related areas, the only problem is how to use this value The information is to our advantage. In other words, the question that we are now
You are facing:


 How to extract time series data?



The purpose of this volume is to present some recent developments in pre-processing, mining, and interpretation of temporal data previously stored Modern information systems. Add the time dimension to the database It produces Time Series Database (TSDB) and introduces new aspects Challenges for data mining and knowledge discovery tasks. This is new Challenges include: finding the most efficient representation of the time series Data, measure the similarity of time series, and detect change points in time Chain, time series classification and  aggregation. 

Some of these problems They were dealt with in the past by time series analysis experts. However, Statistical methods for time series analysis focus on the value chain Represents a single digital variable (for example, a specific share price). 
At Real-time database, time stamped record may contain multiple numbers And the nominal qualities, which may not depend solely on the time dimension But also to each other. To make the task of extracting data more sophisticated, objects in a time series may represent some complex graph Structures rather than vectors of distinct values.
