  1. 21. Investigating the Spectral Bias in Neural Networks

    University essay from KTH/Matematik (Avd.)

    Author : Filip Thor; [2021]
    Keywords : spectral bias; frequency principle; neural networks; machine learning; applied mathematics; spectral bias; neurala nätverk; maskininlärning; tillämpad matematik;

    Abstract : Neural networks have been shown to have astounding performance on a variety of different machine learning tasks and data sets, both for synthetic and real-world data.However, in spite of their widespread usage and implementation, the convergence and the training dynamics of neural networks are neither trivial, nor completely understood.

  3. 22. Analysing the quality of PlaneRCNN plane parameters using a structure from motion system

    University essay from Lunds universitet/Matematik LTH

    Author : Fredrik Österberg; [2021]
    Keywords : structure from motion; PlaneRCNN; neural network; sfm; computer vision; RANSAC; planes; room reconstruction; Mathematics and Statistics; Technology and Engineering;

    Abstract : This report aims to compare the plane parameters given by the PlaneRCNN network with those created by using a Structure from Motion (SfM) solution on the same data. Several datasets are used, and the results from PlaneRCNN are evaluated by using the camera matrices from the SfM solution and applying these along with scaling and coordinate transformations.

    Abstract : Observing the earth from above is a great way of understanding our world better. From space, many complex patterns and relationships on the ground can be identified through high-quality satellite data. READ MORE

  5. 24. Future Electricity Consumption and Wind Power Production in Sweden - Effects of Climate Change

    University essay from Lunds universitet/Matematisk statistik

    Author : Ingrid Torstensson; [2021]
    Keywords : Electricity system; Bias Correction; Quantile Mapping; Climate Model; Emission scenarios; Mathematics and Statistics;

    Abstract : To maintain stability in the Swedish electricity grid, Svenska kraftnät must be able to predict future electricity production and consumption. Earlier this have been done by using historical data. READ MORE

  6. 25. Identification of Phenotypes in Cardiac Arrest Patient Cohorts

    University essay from Lunds universitet/Matematisk statistik

    Author : Rebecca Lütz; [2021]
    Keywords : Mathematics and Statistics;

    Abstract : In this thesis, it is analysed if cardiac arrest patients can be grouped into similar clusters based on different underlying conditions and clinical variables and if there is a difference between clusters in either mortality or neurological outcome as measured by the Cerebral Performance Categories (CPC) scale. The two data sets both contain a targeted temperature management variable which indicates whether or not patients are cooled down upon arrival as well as a variety of continuous and categorical variables.
