  1. 1. Classification of EEG Data Using Convolutional Neural Networks and the Scaled Reassigned Spectrogram

    University essay from Lunds universitet/Matematisk statistik

    Author : Karin Pagels; [2021]
    Keywords : Mathematics and Statistics;

    Abstract : Electroencephalography (EEG) is a medical technique for measuring brain activity through several channels connected to the scalp. Interpreting EEG data is a difficult problem because of the large amount of noise contained in the data. READ MORE

  2. 2. Hierarchical Clustering To Improve Portfolio Tail Risk Characteristics

    University essay from Lunds universitet/Matematisk statistik

    Author : Adam Eidenvall; [2021]
    Keywords : Hierarchical Clustering; Asset Allocation; Portfolio Construction; Graph Theory; Machine Learning; Risk Parity; Regime Shift; Bootstrapping; Walk Forward; Mathematics and Statistics;

    Abstract : Many agree that estimating portfolio risks has better estimation possibilities, than estimations on returns. Therefore investors attempts to construct better, more efficient riskmanaged portfolios by diversifying portfolios through factors rather than traditional asset classes. READ MORE

  3. 3. Optimizing Weighting Factors for Multiple Window Spectrum Estimates

    University essay from Lunds universitet/Matematisk statistik

    Author : Marlon Almström; [2021]
    Keywords : Mathematics and Statistics;

    Abstract : Spectral estimation can be done using different techniques, where averaging the periodogram using multiple windows is one of the techniques. When using multiple windows, the spectral estimate is commonly obtained by having the windows for the subspectra equally weighted. READ MORE

  4. 4. Prediction of quote acceptance in a B2B environment using Random Forests and Gradient Boosting Machines

    University essay from Lunds universitet/Matematisk statistik

    Author : Jesper Gunnarsson; Jacob Tyrberg; [2021]
    Keywords : B2B; pricing; Random Forest; Gradient Boosting; calibration; feature engineering; Mathematics and Statistics;

    Abstract : For a business to be as successful as possible it needs a sound pricing strategy. A B2B environment allows the business more freedom to tailor each quote to maximize the performance.In order to do this, proper understanding of how probable a quote is to succeed is crucial. READ MORE

  5. 5. Multipath Modelling for 60 GHz Short Range Radar

    University essay from Lunds universitet/Matematisk statistik

    Author : Andre Nüsslein; [2021]
    Keywords : Radar; Surveillance; Multipath; Mathematics and Statistics;

    Abstract : If radar surveillance systems are installed near a wall, their radiation is reflected not only from moving objects but also from the wall. In this way, non­existing so­called ghost targets can lead to false detections. This thesis exploits such ghost detections to infer the position and extension of a wall next to a radar sensor.
