This study presents a new method for knowledge discovery in time series databases (TSDB). It uses signal processing and fuzzy logic to predict future time series behavior, demonstrated on stock and weather data.

Area of Science:

  • Data Mining
  • Time Series Analysis
  • Knowledge Discovery

Background:

  • Time series databases (TSDB) present unique challenges for data mining.
  • Extracting meaningful insights from temporal data requires specialized methodologies.
  • Existing methods may not fully capture the complexities of time-dependent datasets.

Purpose of the Study:

  • To introduce a general methodology for knowledge discovery specifically designed for TSDB.
  • To develop a framework for predicting future time series behavior.
  • To address the difficulties associated with data mining in temporal databases.

Main Methods:

  • Data cleaning, filtering, and attribute identification for time series.
  • Utilizing signal processing techniques for data analysis.
