Pattern recognition in financial surveillance with the ARMA-GARCH time series model using support vector machine

作者:

Highlights:

• An auto-correlated financial process is monitored.

• A new method based on SVM is proposed to detect upward and downward shifts.

• A new feature is proposed for the better distinction of step and trend shift patterns.

• A comprehensive simulation study is performed to evaluate the performance.

• The proposed approach is applied to classify patterns in two real cases.
