  1. 1. Do two heads think better than one? Risk Differences in Gender and Team vs. Single Managed Mutual Equity Funds in Sweden

    Kandidat-uppsats,

    Författare :Zelda Harbecke; Hanna Kyséla; [2023-06-29]
    Nyckelord :;

    Sammanfattning : This empirical study examines whether team or single-managed mutual equity funds in the Swedish fund market are more risk-prone conditionally on the management structure during the last five years (2018-2022). Additionally, the gender of each fund manager is analyzed in order to find answers regarding gender's risk approach in investment decisions. LÄS MER

  3. 2. Parameter Inference for Stochastic Models of Gene Expression in Eukaryotic Cells

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Ansar Siddiqui; [2023]
    Nyckelord :;

    Sammanfattning : Simulation models are often used to study a system or phenomenon. However, before a simulation model can be used, its parameter needs to be fit to mimic observed data. This is called the parameter inference problem. LÄS MER

  4. 3. Autoencoder-Based Likelihood-Free Parameter Inference of Gene Regulatory Network

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Liang Cheng; [2023]
    Nyckelord :;

    Sammanfattning : Likelihood-free parameter inference is a well-known statistical methodology that estimates the posterior distribution of model parameters even in cases where the likelihood function is intractable. The performance of this method is highly correlated with the learning of summary statistics, which capture the key features from the high dimensional data such as time series. LÄS MER

  5. 4. Att uppfattas som legitim i klimatomställningen : Medias roll för en aktörs legitimitet

    Kandidat-uppsats, Linköpings universitet/Tema Miljöförändring

  7. 5. Using Social Media and Personality Predictions to Anticipate Startup Success

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Daniel Stenson; [2023]
    Nyckelord :Machine Learning; Startup Success Predictions; Founder Personalities; Natural Language Processing; Social Media Analysis; Big 5 Personality Framework; Feed-forward Neural Network; XGBoost.; Mathematics and Statistics;

    Sammanfattning : This thesis explores the potential of integrating predicted founder personalities, based on the Big 5 Personality Framework, into Machine Learning (ML) models to enhance the accuracy of early-stage startup success predictions. Leveraging Natural Language Processing (NLP) techniques, we extracted personality insights from founders' tweets, focusing on US startups funded between 2013 and 2015. LÄS MER
