Adding network features

Enriching data with network features and other kinds of variables improves a model's ability to detect fraud.

The network net is based on the transactional dataset transfers from different accounts. The data account_info contains details on these accounts which are the nodes of the network. You can add network features to account_info like degree, closeness and betweenness.
