# Data Mining using Morlet Wavelets for Financial Time Series

### Reginald Bolman, Thomas Boucher

#### Abstract

Wavelets are a family of signal processing techniques which have a growing popularity in the artificial intelligence community. In particular, Morlet wavelets have been applied to neural network time series trend prediction, forecasting the effects of monetary policy, etc. In this paper, we discuss the application of Morlet wavelets to discover the morphology of a time series cyclical components and the unsupervised data mining of financial time series in order to discover hidden motifs within the data. To perform the analysis of a given time series and form a comparison between the morphologies this paper proposes the implementation of the “Bolman Time Series Power Comparison” algorithm which will extract the pertinent time series motifs from the underlying dataset.
