Credit Scoring, Artificial Intelligence and Quantum Machine Learning






This rigorous course is designed to impart skills necessary for creating and calibrating credit scoring models, including calculating default probabilities (PD) and validating these models. Participants will explore a range of machine learning approaches from traditional methods to quantum and probabilistic techniques, and learn how to leverage artificial intelligence for automating these processes.


Participants will gain proficiency in both conventional and cutting-edge models for credit scoring during the stages of credit admission and monitoring. This includes handling vast datasets to construct comprehensive credit and behavior scoring systems.


The course also delves into advanced data analytics, covering topics like sampling, exploratory analysis, feature engineering, segmentation, and outlier detection.


A variety of machine learning techniques will be discussed—ranging from supervised and unsupervised learning to reinforcement learning—specifically applied to developing tools for credit scoring. Well-established methods like logistic regression and other innovative machine learning techniques such as decision trees, naive Bayes, K-nearest neighbors, LASSO logistic regression, random forests, neural networks, Bayesian networks, Support Vector Machines, and gradient boosting trees will be explored.


The application of deep learning in building robust credit scoring models suitable for banking applications will be covered extensively. This includes the use of various neural network architectures such as feedforward, convolutional, recurrent, and adversarial generative networks, alongside Fermac Risk’s proprietary methodology for managing and interpreting deep learning models to prevent the pitfalls of black box scenarios.


Instruction on tuning hyperparameters, which are crucial for controlling the learning process and optimizing model performance, will be provided along with techniques like grid search, random search, and Bayesian optimization.


The course provides over 20 distinct credit scoring models using different methodologies across multiple programming environments like R, Python, Jupyterlab, Tensorflow, and SAS. This spans models for various credit aspects including origination, behavior, recovery, income, and churn.


Advanced techniques for calibrating risk parameters for the IRB and IFRS 9 PD are included, covering methods from adjustment to central tendency to deep learning models for PD lifetime calibration under IFRS 9.


The curriculum introduces automated machine learning (AutoML), enhancing the ability of risk analysts to develop, scale, and validate high-quality machine learning models efficiently.


Participants will also explore probabilistic machine learning techniques, like Bayesian neural networks, to construct credit scoring models, alongside best practices for model validation, particularly focusing on AI-driven financial tools as per European regulatory standards.


Finally, the course highlights the emerging field of Quantum Machine Learning, discussing its potential to revolutionize financial services through enhanced computational speeds and capabilities using quantum algorithms.


This comprehensive program aims to equip participants with the skills to utilize advanced computing technologies, including quantum and tensor networks, for machine learning calculations, preparing them for significant advancements in the financial sector.



The Course is aimed at professionals from financial institutions interested in developing powerful credit scoring models and calibrating their output, as well as model managers in credit risk and data science departments.


For a better understanding of the topics, the participant must know statistics and mathematics. You can benefit from quantum computing technologies without needing to have knowledge of quantum physics.
