THE MS2DISCOVERY INTERDISCIPLINARY RESEARCH INSTITUTE Trimodal Deep Learning for Micro and SME Credit Scoring Waterloo | Canada Cristián Bravo | Western University In recent times there has been a rapid development of Deep Learning techniques capable of extracting information from unstructured sources of data such as images, sound and text. In our presentation, we explore the application of the latest Deep Learning techniques to assess the feasibility of automating some of the Micro and SME lending process. We apply the most recent developments from the field of Deep Learning including the current state of the art in Natural Language Processing (NLP), the Google BERT model, for the prediction of loan default over 40,000 Micro and SME loans. Our initial results suggest that the text loan assessment are surprisingly predictive; however, when combined with traditional credit scoring variables, no additional performance improvement is gained in terms of AUC of Accuracy. Despite no

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
