Abstract

In this bachelor's thesis we give a survey of methods to learn meaningful graphs from time series. Graph representations of data sets give us many possibilities to enhance the processing, analysis, and visualization of data. Specifically, they allow the use of new approaches to clustering data. Related to this, we have studied spectral clustering algorithms using different Laplacian matrices.

As a practical application, these techniques are used to find clusters in the stock market with a focus on comparing the clusters structure with the industry classification of companies. Finally, we have also tried to visualize the increase of systemic risk associated with economical crisis.
