  1. 21. Self-adaptive random walk with pesudo-gradients for genetic evolution of an artificial neural network

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Author : Robin Emanuelsson; [2020]
    Keywords : Physics and Astronomy;

    Abstract : To optimize the weights in an artificial neural network most methods rely gradients, which are not always obtainable or desirable. Evolutionary algorithms are instead based on Darwinian evolution where no derivative is needed. READ MORE

  3. 22. Exploring the application of neural networks in predictions of nuclear binding energies

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Martin Waites; [2020]
    Keywords : neural networks; drip-line; nuclear physics; binding energy; exotic nuclei; Hartree-Fock-Bogolyubov; Physics and Astronomy;

    Abstract : In this project the locations of the proton and neutron drip-lines are predicted using neural networks and theoretical data obtained by applying the HFBTHO program. For each of the neural networks a comparison is made between neural network predictions and experimental data in the region experimental data exists. READ MORE

  4. 23. Deep Learning Approach to Material Properties

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Love Pettersson; [2020]
    Keywords : Artificial Neural Networks; ANN; Deep learning; Density functional theory; DFT; Perovskites; Machine learining; Science General;

    Abstract : In this thesis, we consider a deep learning approach to predict material properties. Primarily we study artificial neural networks (ANN), which predict the energy distance to the convex hull (measure of stability) of perovskites. Further, we explore if the networks can be generalised to predict band gaps and unit cell volume. READ MORE

  5. 24. Data Biopolitics for Peace? ‘Peace’ as a Technique of Power for Social Control

    University essay from Malmö universitet/Fakulteten för kultur och samhälle (KS)

    Author : Veronika Wilhelmová; [2020]
    Keywords : ;

    Abstract : In light of Sweden’s increased reliance on surveillance for ensuring security within its own borders, as well as the promotion of big data use for the purposes of predictive analyses in support of peacebuilding, these developments warrant critical assessment. This thesis engages in an explanatory critique of the discursive (re-)definitions of peace in 16 officially released online documents of the Government Offices of Sweden against the backdrop of the increasing use of data technology.

  6. 25. Extracting contact surfaces from point-cloud data for autonomous placing of rigid objects

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

    Author : Carolina Bianchi; [2020]
    Keywords : ;

    Abstract : Nowadays, thousands of humanworkers engage daily in non-creative and physically demanding tasks such as order-picking-and-placing. This task consists of collecting different goods from warehouse shelves and placing them in a container to fulfill an order. READ MORE
