Deep Learning and Large Scale Models for Bank Transactions

Abstract: The success of Artificial Intelligence (AI) in different research and application areas has increased the interest in adopting Deep Learning techniques also in the financial field. Particularly interesting is the case of financial transactional data, which represent one of the most valuable sources of information for banks and other financial institutes. However, the heterogeneity of the data, composed of both numerical and categorical attributes, makes the use of standard Deep Learning methods difficult. In this paper, we present UniTTAB, a Transformer network for transactional time series, which can uniformly represent heterogeneous time-dependent data, and which is trained on a very large scale of real transactional data. As far as we know, the dataset we used for training is the largest real bank transactions dataset used for Deep Learning methods in this field, being all the other common datasets either much smaller or synthetically generated. The use of this very large real training dataset, makes our UniTTAB the first foundation model for transactional data.
