  1. 1. XZDDF Bootstrapping in Fully Homomorphic Encryption

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Simon Ljungbeck; [2024]
    Keywords : Fully Homomorphic Encryption; Homomorphic Encryption; Bootstrapping; Blind Rotation; XZDDF; Technology and Engineering;

    Abstract : Despite the vast research on the topic in recent years, fully homomorphic encryption schemes remain time-inefficient. The main bottleneck is the so-called bootstrapping, whose purpose is to reduce noise that has accumulated after having performed homomorphic operations on a ciphertext. READ MORE

  3. 2. Bootstrapping methods for assessing causality in survival analysis: A case study on major adverse cardiovascular events

    University essay from Lunds universitet/Matematisk statistik

    Author : Paulina Benthem Ciano; [2023]
    Keywords : Causality; Graphical models; Bootstrap; Survival analysis; Additive hazards model.; Mathematics and Statistics;

    Abstract : The combination of graphical models with Aalen's additive hazards model, resulting in a model known as dynamical path analysis, permits assessing the effects of different variables on times until an event and decomposing these total effects into direct and indirect effects. This thesis proposes novel bootstrapping methods designed for left-truncated right-censored data, conditional on covariates within the framework of Aalen's additive hazards model, in order to obtain confidence intervals for the estimates.

  4. 3. Evaluating Bag Of Little Bootstraps On Logistic Regression With Unbalanced Data

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Henrik Bark; [2023]
    Keywords : Bootstrapping; Logistic Regression; Bag of Little Bootstraps; BLB; Penalized Maximum Likelihood Estimation; PMLE;

    Abstract : The Bag of Little Bootstraps (BLB) was introduced to make the bootstrap method more computationally efficient when used on massive data samples. Since its introduction, a broad spectrum of research on the application of the BLB has been made. READ MORE

  5. 4. Investigating the Estimation of the infection rate and the fraction of infections leading to death in epidemiological simulation

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Jakob Gölén; [2023]
    Keywords : Epidemics; Compartmental Models; Parameter Inference; Synthetic Bootstrap; Infection Rate;

    Abstract : The main goal of this project is to investigate the behaviors of parameters used when modeling an epidemic. A stochastic SIHDRe model is used to simulate how an epidemic evolves over time. READ MORE

  6. 5. The funding process in female-led capital-intensive start-ups

    University essay from Uppsala universitet/Företagsekonomiska institutionen

    Author : Ximena Samuelsson-Allendes; Kyaw Khaing Hein; [2023]
    Keywords : capital-intensive; entrepreneurship; female founder; financing; gender bias; gender gap; investor; key factors; start-up; kapitalintensiv; entreprenörskap; kvinnlig grundare; finansering; köns bias; könsskillnader; investerare; nyckelfaktorer; start up;

    Abstract : The purpose of this study is to present how female entrepreneurs in Sweden raise capital for their start-ups and if there are common key factors presented among those who succeed. The entrepreneurs interviewed have all successfully raised capital. The research shows that female founders only have access to 1% or less of the capital in Sweden. READ MORE
