Explaining Explainable AI in FinTech World
In recent years, the usage of machine learning techniques has grown substantially, both in industry and research. New types of models based on deep neural networks (DNNs) are now becoming ubiquitous in the industry. These models are extremely powerful and have substantially improved the state of the art in many domains. This improvement, however, is achieved at a cost. Compared to classical machine learning algorithms (e.g., Logistic Regression, SVM), these models are more complex, and typically use many orders of magnitudes more parameters.
