Foundation Models for Credit Risk Prediction: A Game Changer?
Bart Baesens, Andreas Goethals, Stefan Lessmann +10
Predictive models play a pivotal role in credit risk management, guiding critical decisions through accurate estimation of default probabilities and losses. Extensive research has…
Staging by the Book: Automatic Sleep Stage Classification Using Scoring Rules
Emil Hardarson, Konstantin Popov, Sigridur Sigurdardottir +3
Automated sleep staging is commonly approached as a supervised machine learning problem, with deep learning methods dominating recent research. While machine learning models achiev…
Data-Local Autonomous LLM-Guided Neural Architecture Search for Multiclass Multimodal Time-Series Classification
Emil Hardarson, Luka Biedebach, Ãmar Bessi Ãmarsson +3
Applying machine learning to sensitive time-series data is often bottlenecked by the iteration loop: Performance depends strongly on preprocessing and architecture, yet training of…
Chaos into Order: Neural Framework for Expected Value Estimation of Stochastic Partial Differential Equations
Ãsak Pétursson, MarÃa Ãskarsdóttir
Stochastic partial differential equations (SPDEs) describe the evolution of random processes over space and time, but their solutions are often analytically intractable and computa…
Generalized Distribution Prediction for Asset Returns
Ãsak Pétursson, MarÃa Ãskarsdóttir
We present a novel approach for predicting the distribution of asset returns using a quantile-based method with Long Short-Term Memory (LSTM) networks. Our model is designed in two…
