  1. 11. Regularization Methods and High Dimensional Data: A Comparative Study Based on Frequentist and Bayesian Methods

    University essay from Lunds universitet/Statistiska institutionen

    Author : Markus Gerholm; Johan Sörstadius; [2024]
    Keywords : Linear regression; high dimensional data; regularization; Bayesian methods; Mathematics and Statistics;

    Abstract : As the amount of high dimensional data becomes increasingly accessible and common, the need for reliable methods to combat problems such as overfitting and multicollinearity increases. Models need to be able to manage large data sets where predictor variables often outnumber the amount of observations. READ MORE

  2. 12. Classifying femur fractures using federated learning

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Hong Zhang; [2024]
    Keywords : Atypical femur fracture; Federated Learning; Neural Network; Classification;

    Abstract : The rarity and subtle radiographic features of atypical femoral fractures (AFF) make it difficult to distinguish radiologically from normal femoral fractures (NFF). Compared with NFF, AFF has subtle radiological features and is associated with the long-term use of bisphosphonates for the treatment of osteoporosis. READ MORE

  3. 13. Evaluating and optimizing Transformer models for predicting chemical reactions

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Siva Manohar Koki; Supriya Kancharla; [2023-10-23]
    Keywords : Chemformer; transformer; evaluation; explainable AI; fine-tuning; machine learning;

    Abstract : In this thesis, we assess the effectiveness of a transformer model specifically trained to predict chemical reactions. The model, named Chemformer, is a sequence-tosequence model that uses the transformer’s encoder and decoder stacks. READ MORE

  4. 14. The Power of Credit Scoring: Evaluating Machine Learning and Traditional Models in Swedish Retail Banking

    University essay from Göteborgs universitet/Graduate School

    Author : Emma von der Burg; Saga Strömberg; [2023-06-29]
    Keywords : ;

    Abstract : In this paper, we investigate and compare different credit scoring models, with special attention paid to machine learning approaches outperforming traditional models. We explore a recently proposed method called the PLTR model, which is a combination of machine learning and traditional logistic regression. READ MORE

  5. 15. Value at Risk Estimation using GARCH Family Models: A Comparison of Different Specifications and Distributions.

    University essay from Göteborgs universitet/Institutionen för nationalekonomi med statistik

    Author : Khaled Jrideh; [2023-05-26]
    Keywords : ;

    Abstract : The objective of this study is to compare the performance of different GARCH models, under various conditional distribution assumptions, to predict one-day-ahead Value-at-Risk (VaR) for three stocks: Swedbank, Handelsbanken, and SEB over the Covid-19 period. The performance is evaluated using Kupiec, Christoffersen tests and the Quadratic Loss. READ MORE
