Time Series Data Processing And Application System's Developing

Data mining is a rapid developing subject both at home and abroad in the 1990s; it concerns a lot of fields, such as artificial intelligence, statistics, machine learning, database, etc...Data processing is an important step in data mining (knowledge discovery), it can improved the quality of the data mining through processing the data which include noise, incomplete, even inconsistent factor in industrial enterprise's database system, and improved the performance of the pattern knowledge which was got by data mining.This paper research and analyze time series data processing based on industrial time series data which is produced by Tianjing ethylene pryolysis furnace. Firstly, we discussed the characteristic of process industrial data and the research contents of time series. Then, we processed the vacancy, noisy data and realized the data compressing using following methods: filling vacancy data by max values, even values and inserting values, removing the noisy by bin, data compressing and piecewise linear representation data processing. We focus on researched and realized the...
