Online banking activities are constantly growing and will become even more common as open banking platforms evolve. One side effect of this trend is the growth in fraudulent attempts. To address this problem, in the first part of the talk, we will propose an attention based architecture for classifying online banking transactions as either fraudulent or genuine. Our method allows transparency to the decision of the classifier by pointing out the most dominant transactions in the sequence and the most dominant features in each transaction. Experiments conducted on real online banking data originated from third party vendors who specialized in online banking fraud detection. They demonstrate the effectiveness of our method in both classification accuracy and interpretability of the results. In the second part of the talk, we will discuss a transfer learning algorithm that we developed to minimize the silent period of new banks and to improve the detection accuracy of banks with a small amount of labeled data.
