  1. 21. Artificial Neural Networks and Inductive Biases for Multi-Instance Multi-Modal Tabular Data : A Case Study for Default Probability Estimation in Small-to-Medium Enterprise Lending

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Gustav Röhss; [2022]
    Keywords : ;

    Abstract : The success of artificial neural networks in homogeneous data domains such as images, textual data, and audio and other signals has had considerable impact on Machine Learning and science in general. The domain of heterogeneous tabular data, while arguably much more common, remains much less explored with regards to artificial neural networks and deep learning. READ MORE

  3. 22. Combining Continuous and Event-based Hydrological Modeling in Kävlinge River Basin with HEC-HMS

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Wenli Hu; [2022]
    Keywords : HEC-HMS; SCS-CN; Climate Change; GIS; Flood; Technology and Engineering;

    Abstract : Prediction of flood and evaluation of the impact of climate change in a catchment needs to be correctly estimated, which can be accomplished by hydrological modelling in HEC-HMS. In this paper, the objectives were to gain an understanding of the rainfall-runoff process and estimate the flood frequency curve in the Kävlinge River Basin. READ MORE

  4. 23. Towards Deep Learning Accelerated Sparse Bayesian Frequency Estimation

    University essay from Lunds universitet/Matematisk statistik

    Author : Mika Persson; [2022]
    Keywords : Bayesian Statistics; Deep Learning; Frequency Estimation; Generative Adversarial Networks; Artificial Neural Networks; Statistical Modelling; Mathematics and Statistics;

    Abstract : The Discrete Fourier Transform is the simplest way to obtain the spectrum of a discrete complex signal. This thesis concerns the case when the signal is known to contain a small (unknown) number of frequencies, not limited to the discrete Fourier frequencies, embedded in complex Gaussian noise.

  5. 24. Improving term structure measurements by incorporating steps in a multiple yield curve framework

    University essay from Linköpings universitet/Produktionsekonomi

    Author : Gustav Villwock; Clara Rydholm; [2022]
    Keywords : Finance; Interest rates; Term structure measurement; Monte Carlo; Financial mathematics; Yield curve; Policy rates; Multiple yield curve framework; Stochastic programming; Risk factor modeling; Hedging; Performance attribution; Principle component analysis; GARCH; Maximum likelihood estimation; Copula;

    Abstract : By issuing interest rate derivative contracts, market makers such as large banks are exposed to undesired risk. There are several methods for banks to hedge themselves against this type of risk; one such method is the stochastic programming model developed by Blomvall and Hagenbjörk (2022). READ MORE

  6. 25. Applying Nonlinear Mixed-Effects Modeling to Model Patient Flow in the Emergency Department : Evaluation of the Impact of Patient Characteristics on Emergency Department Logistics

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Umberto Rosamilia; [2022]
    Keywords : Emergency Department; Nonlinear Mixed-Effects Modeling; Healthcare Logistics; Patient Flow Modeling; Patient Pathways; Markov Process; Akutmottagning; Icke-Linjär Blandad Effektmodellering; Vårdlogistik; Patientflödesmodellering; Patientflöde; Markovprocess;

    Abstract : Emergency departments are fundamental for providing high-quality care, and their operations directly impact the logistics of the hospitals in their entirety. Poor emergency department performance leads to delays, prolonged hospitalization, and improper allocation of resources, reducing the quality of the provided care and increasing costs. READ MORE
