1. 21. Self-Play Reinforcement Learning for Finding Intrusion Prevention Strategies

   Master-uppsats, KTH/Matematisk statistik

   Författare :Jakob Stymne; [2022]
   Nyckelord :Network security; automation; reinforcement learning; Markov Security Games; Neural Fictitious Self Play; Nätverkssäkerhet; automatisering; förstärkningsinlärning; Markovianska säkerhetsspel; Neural Fictitious Self Play;

   Sammanfattning : This Master thesis studies automated intrusion prevention using self-play reinforcement learning. We extend a decision-theoretic model of the intrusion prevention use case based on optimal stopping theory proposed in previous work to a game-theoretic setting. LÄS MER

   Sammanfattning : Påverkade covid-19-pandemin fotbollsallsvenskan för herrar i Sverige? Vad hände när matcherna spelades utan publik? I detta examensarbete undersöks bland annat fenomenet hemmaplansfördel med tanke på covid-19-pandemin. Syftet med arbetet är att studera och analysera hur hemmaplansfördelen, antal gjorda mål, antalet varnade och utvisade spelare i herrallsvenskan har förändrats mellan säsongerna 2018, 2019, 2020 och 2021 med tanke på covid-19-pandemin.

4. 23. Deep Learning Approach for Time- to-Event Modeling of Credit Risk

   Master-uppsats, KTH/Matematisk statistik

   Författare :Mehnaz Kazi; Natalija Stanojlovic; [2022]
   Nyckelord :Survival Analysis; Credit Risk; Credit Scoring; Time-To-Event; Default Probability; Överlevnadsanalys; Kreditrisk; Kreditprövning; Tid-till-utfall; Sannolikhet för fallissemang;

   Sammanfattning : This thesis explores how survival analysis models performs for default risk prediction of small-to-medium sized enterprises (SME) and investigates when survival analysis models are preferable to use. This is examined by comparing the performance of three deep learning models in a survival analysis setting, a traditional survival analysis model Cox Proportional Hazards, and a traditional credit risk model logistic regression.

5. 24. Evaluation of the decision-making process for credit decisions at Preem AB

   Kandidat-uppsats, KTH/Matematisk statistik

   Författare :Annie Holgersson; Theresa Döös; [2022]
   Nyckelord :credit; applied mathematics; statistics; logistic regression; kredit; tillämpad matematik; statistik; logistisk regression;

   Sammanfattning : The purpose of the following bachelor thesis report within mathematical statistics was to evaluate the decision making process at the credit department at Preem AB. The study used a logistic regression model to find a relationship between the probability of an application for credit being accepted and some quantitative and categorical factors about the applicant.

7. 25. Gradually Changing Gender Attribution of Speech Recordings Using Interpolated Filters

   Master-uppsats, Lunds universitet/Matematisk statistik

   Författare :Mira Kjellin; [2022]
   Nyckelord :Mathematics and Statistics;

   Sammanfattning : When we listen to human speech, one of the first characteristics we assess is the gender of the speaker. For individuals who suffer from gender dysphoria, this may cause them to be negatively impacted by their voice not matching their gender identity. Therefore, some persons attempt to change their voices with a speech-language therapist. LÄS MER
