Abstract:
The rapid development of artificial intelligence methods contributes to their
wide applications for forecasting various financial risks in recent years. This
study introduces a novel explainable case-based reasoning (CBR) approach without
a requirement of rich expertise in financial risk. Compared with other black-box
algorithms, the explainable CBR system allows a natural economic interpretation
of results. Indeed, the empirical results emphasize the interpretability of the
CBR system in predicting financial risk, which is essential for both financial
companies and their customers. In addition, results show that the proposed
automatic design CBR system has a good prediction performance compared to other
artificial intelligence methods, overcoming the main drawback of a standard CBR
system of highly depending on prior domain knowledge about the corresponding
field.
