  1. 11. Evaluation of Probabilistic Programming Frameworks

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Carl Munkby; [2022]
    Keywords : Computational statistics; Bayesian statistics; Probabilistic programming; Probabilistic modelling; Stan; TensorFlow Probability; Pyro; NumPyro; Markov Chain Monte Carlo; Hamiltonian Monte Carlo; NUTS;

    Abstract : In recent years significant progress has been made in the area of Probabilistic Programming, contributing to a considerably easier workflow for quantitative research in many fields. However, as new Probabilistic Programming Frameworks (PPFs) are continuously being created and developed, there is a need for finding ways of evaluating and benchmarking these frameworks. READ MORE

  3. 12. KL/TV Reshuffling : Statistical Distance Based Offspring Selection in SMC Methods

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Oskar Kviman; [2022]
    Keywords : ;

    Abstract : Over the years sequential Monte Carlo (SMC), and, equivalently, particle filter (PF) theory has enjoyed much attention from researchers. However, the intensity of developing innovative resampling methods, also known as offspring selection methods, has long been declining, with most of the popular schemes aging back two decades.

  4. 13. Effects of power-law correlated disorder on a 3D XY model

    University essay from KTH/Fysik

    Author : Philip Broms; [2022]
    Keywords : Condensed matter physics; Ising model; XY model; Markov Chain Monte Carlo; Phase transition; Disorder; Theoretical physics; Wolff algorithm; Kondenserade materians teori; Isingmodell; XY-modell; Markovkedje-Monte Carlo-metoder; Teoretisk fysik; Oordning; Fasövergångar; Wolffalgoritmen;

    Abstract : This thesis investigates the effects of power-law correlated disorder on a three-dimensional XY model and the Weinrib-Halperin disorder relevance criterion’s pre-dictive ability. Ising models are used as a map to realise disorder couplings. READ MORE

  5. 14. Quantum Error Correction Using Graph Neural Networks

    University essay from Göteborgs universitet / Institutionen för fysik

    Author : Valdemar Bergentall; [2021-06-17]
    Keywords : Quantum error correction; surface code; graph neural networks;

    Abstract : A graph neural network (GNN) is constructed and trained with a purpose of using it as a quantum error correction decoder for depolarized noise on the surface code. Since associating syndromes on the surface code with graphs instead of grid-like data seemed promising, a previous decoder based on the Markov Chain Monte Carlo method was used to generate data to create graphs.

  6. 15. Markov Chain Monte Carlo (MCMC) and Bayesian Inference for Gravitational Waves

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Christine Andersson; [2021]
    Keywords : Gravitational Waves; LISA; LISA mission; Bayesian Inference; Markov Chain Monte Carlo; MCMC; Bayes’ Theorem; stochastic sampling; Metropolis Hastings; histograms; Physics and Astronomy;

    Abstract : The Laser Interferometer Space Antenna (LISA) is a space borne gravitational wave detec- tor set to launch in 2034, with the objective of detecting and studying the Gravitational Waves (GWs) of our universe. So far, ground-based detectors such as the Laser Interferometer Gravitational-Wave Observatory (LIGO) have been successful in detecting GWs, but the limitations of ground based detectors is what makes LISA so special.
