A New Pattern Representation Method for Time-Series Data
نویسندگان
چکیده
The rapid growth of Internet Things (IoT) and sensing technologies has led to an increasing interest in time-series data analysis. In many domains, detecting patterns IoT interpreting these are challenging issues. There several methods analysis that deal with issues such as volume velocity streams. However, analysing the content streams extracting insights from dynamic is still a task. this paper, we propose pattern representation method which represents frames vectors by first applying Piecewise Aggregate Approximation (PAA) then Lagrangian Multipliers. This allows representing continuous series can be used processed various higher-level methods. We introduce new change point detection uses constructed its evaluate compare our Blocks Eigenvalues Algorithm (BEATS) Symbolic approXimation (SAX) cluster datasets. have evaluated algorithm using UCR datasets also healthcare dataset. evaluation results show significant improvements proposed method.

15 صفحه اولA new adaptive exponential smoothing method for non-stationary time series with level shifts
Simple exponential smoothing (SES) methods are the most commonly used methods in forecasting and time series analysis. However, they are generally insensitive to non-stationary structural events such as level shifts, ramp shifts, and spikes or impulses. Similar to that of outliers in stationary time series, these non-stationary events will lead to increased level of errors in the forecasting pr...

A Method for Protecting Access Pattern in Outsourced Data
Protecting the information access pattern, which means preventing the disclosure of data and structural details of databases, is very important in working with data, especially in the cases of outsourced databases and databases with Internet access. The protection of the information access pattern indicates that mere data confidentiality is not sufficient and the privacy of queries and accesses...
متن کاملA New Method for Time-Delay Compensation in Control Systems
In this paper a new method is introduced and investigated for removing the destabilizing effects of time-delay parameter in control loops. The concept of the method is taken from the knowledge concerning the dynamic behaviour of irrational transfer functions (Ir-TF), which is discussed and investigated elswhere in frequency response domain and is explained briefly here. Ir-TFs, which are we...
