  1. 41. Outlier-Robust Dynamic Portfolio Optimization based on Bear-Bull-Regimes

    University essay from Lunds universitet/Matematisk statistik

    Author : Emil Eliasson; Linus Hamlin; [2018]
    Keywords : Mathematics and Statistics;

    Abstract : The work in this thesis is meant to improve an existing algorithm described in Nystrup (2017). As the original model uses a normal distribution to approximate the daily logarithmic returns, the authors of this thesis aim to improve the approximation by using Student’s t-distribution which may be a better approximation of financial data.

  3. 42. Bayesian Parametrisation ofIn Silico Tumour Models

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Jonas Radvilas Umaras; [2018]
    Keywords : ;

    Abstract : Technological progress in recent decades has allowed researchers to utilise accurate but computationally demanding models. One example of this development is the adoption of the multi-scale modelling technique for simulating various tissues. These models can then be utilised to test the efficacy of new drugs, e.g. READ MORE

  4. 43. An estimator of winter loss of honey bees in Sweden

    University essay from Lunds universitet/Matematisk statistik

    Author : Elenor Hagö; [2018]
    Keywords : Mathematics and Statistics;

    Abstract : The aim of this thesis is to suggest a statistical model to estimate the loss rates of honey bees during winter in Sweden. The estimator is to be based on annual summary statistics, collected by the Swedish beekeeping organisation. READ MORE

  5. 44. On Bayesian optimization and its application to hyperparameter tuning

    University essay from Linnéuniversitetet/Institutionen för matematik (MA)

    Author : Antonio Matosevic; [2018]
    Keywords : Optimization; Bayesian statistics; Hyperparameter tuning; Machine learning;

    Abstract : This thesis introduces the concept of Bayesian optimization, primarly used in optimizing costly black-box functions. Besides theoretical treatment of the topic, the focus of the thesis is on two numerical experiments. READ MORE

  6. 45. Analysis of forklift data – A process for decimating data and analyzing fork positioning functions

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Gustav Sternelöv; [2017]
    Keywords : Statistics; CAN data; autoregressive; AR; decimation; signal processing; bayesian hierarchical model;

    Abstract : Investigated in this thesis are the possibilities and effects of reducing CAN data collected from forklifts. The purpose of reducing the data was to create the possibility of exporting and managing data for multiple forklifts and a relatively long period of time. READ MORE
