    Sammanfattning : Phylogeny, the study of evolutionary relationships among species and other taxa, plays a crucial role in understanding the history of life. Bayesian analysis using Markov chain Monte Carlo (MCMC) is a widely used approach for inferring phylogenetic trees, but it suffers from slow convergence in higher dimensions and is slow to converge.

  3. 2. A Method to Improve the Security of Information Diffusion in Complex Networks— Node Trust Value Management Mechanism

    Magister-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Rahul Lal Radhakrishnan; [2020]
    Nyckelord :;

    Sammanfattning : In a sensing field-based placement of nodes the communication happens from the data acquisition points to the control center which is the receiver of data acquisition. In this project an algorithm based on data sense points trust value updating is used which will find out the value of the trust level dynamically once the trust level is found out it will pick the forwarded data sense points based on highest value of trust.

  4. 3. Multipel regressionsanalys av variabler som paverkar BNP

    Kandidat-uppsats, KTH/Matematik (Inst.)

    Författare :Carl Cronsioe; Marcus Ribbenstedt; [2014]
    Nyckelord :;

    Sammanfattning : In this report a model was constructed in order to determine how a number of covariates influence the gross domestic product, GDP. The covariates were chosen depending on their expected influence on GDP, for example education and life expectancy. The data used in this report are collected from the World Bank. LÄS MER

  5. 4. A Digital Theory of Knowledge

    Kandidat-uppsats, Lunds universitet/Teoretisk filosofi

    Författare :Kristian Rönn; [2012]
    Nyckelord :Solomonoff; Kolmogorov; complexity; Turing; digital philosophy; ontology; epistemology; reliabilism; Bayes.; Philosophy and Religion;

    Sammanfattning : The goal with this paper is to formally define knowledge from the assumption that our universe is computable. Based on this assumption, we will formulate a minimalist ontology that will be the theoretical basis for our formal definition of knowledge. LÄS MER
