  1. 11. A Study of the Loss Landscape and Metastability in Graph Convolutional Neural Networks

    University essay from KTH/Matematisk statistik

    Author : Sofia Larsson; [2020]
    Keywords : Graph neural networks; Graph convolutional neural networks; Loss landscape; Gradient descent; Stochastic gradient descent; Stochastic gradient Langevin dynamics; Grafneurala nätverk; grafiska faltningsnätverk; lösningslandskap; gradientmetoder; stokastiska gradientmetoder; stokastisk gradient Langevin dynamik;

    Abstract : Many novel graph neural network models have reported an impressive performance on benchmark dataset, but the theory behind these networks is still being developed. In this thesis, we study the trajectory of Gradient descent (GD) and Stochastic gradient descent (SGD) in the loss landscape of Graph neural networks by replicating Xing et al. READ MORE

  3. 12. Probabilistic Assessment of Pile Drivability in Swedish Soils

    University essay from KTH/Jord- och bergmekanik

    Author : MAEDEH ALINEJAD KORDMAHALLEH; [2020]
    Keywords : Pile refusal; Monte Carlo method; probabilistic model; boulder.;

    Abstract : Site investigations are often performed prior to the design of pile foundations with the aim to collect data regarding soil properties including boulder content. The obtained data is typically limited due to non-homogeneous characteristic of the soil. READ MORE

  4. 13. Capture of interstellar objects in the Solar system

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Jonathan Petersson; [2020]
    Keywords : interstellar objects; Physics and Astronomy;

    Abstract : Research on InterStellar Objects (ISOs) has been done for several decades, however, the first observed ISO in the Solar system was only recently discovered in 2017. It was named 1I/'Oumuamua and was only passing though the Solar system, but this may not be the case for all objects of its kind. READ MORE

  5. 14. The fate of pebbles and planetesimals entering protoplanetary envelopes

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Emil Zadera; [2019]
    Keywords : Planet formation; planet; protoplanet; protoplanetary envelope; protoplanetary atmosphere; protoplanetary growth; planetary growth model; accretion rate; vapour blob; vapourblob; vapour planet; transport of water; water on planet; pebbles; planetesimals; pebble accretion; planetesimal accretion; meteors; ablation; fragmentation; sublimation; protoplanetary disk; MMSN; accretion window; accretion channel; accretion; destruction; disruption; terminal velocity; gas; gasflow; shearingbox; exoplanet; Physics and Astronomy;

    Abstract : Planetary embryos grow by the accretion of solid dust-material, ranging from cm- to m-sized pebbles up to km-sized planetesimals. However, the underlying size-distribution of the accreted material is poorly understood. READ MORE

  6. 15. The Impact of Sound on Player Experience - A literature study on how players experience the encounter with sound in horror-games

    University essay from Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Author : Sebastian Wöhrman; Nael Ningalei; [2018]
    Keywords : Artificial Intelligence; Player experience; State of emotion; Sound impact; Horror-game sound; Heart rate;

    Abstract : Player decision modeling can provide useful guidance to understand player performance in games. This information is used to increase consideration of player characteristics from the user’s perspective and develop more user-centered video games. READ MORE
