  1. 1. Market Surveillance Using Empirical Quantile Model and Machine Learning

    University essay from KTH/Matematik (Avd.)

    Author : Daniel Landberg; [2022]
    Keywords : Market surveillance; Outlier detection; Empirical quantiles; Empirical distribution; Isolation forest; Principal Component Analysis; PCA; Finance; Marknadsövervakning; Extremvärdes upptäckt; Empiriska kvantiler; Empirisk distribution; Isolationsskog; Huvudkomponent analys; Finans;

    Abstract : In recent years, financial trading has become more available. This has led to more market participants and more trades taking place each day. The increased activity also implies an increasing number of abusive trades. To detect the abusive trades, market surveillance systems are developed and used. READ MORE

  3. 2. Monte Carlo Integration: A Comparison to Numerical Quadrature

    University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

    Author : Mirjam Karlsson-Müller; [2021]
    Keywords : Monte Carlo Methods; Approximation of Integrals; Numerical Quadrature; Curse of Dimensionality; Integrals; Monte Carlo; Mathematics and Statistics;

    Abstract : Integrals are present everywhere in science, and their computation an emphasis in education. When methods of exact computation fail, a great variety of methods of approximation can step in. This project is interested in the Monte Carlo integration methods, an approach, where the integral is approximated based on the Law of Large Numbers. READ MORE

  4. 3. Learning representations of features of fish for performing regression tasks

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

    Author : Kristmundur Jónsson; [2021]
    Keywords : Representation learning; Deep Learning; regression; auto encoder; Variational auto encoder; Representationsinlärning; Djupinlärning; Regression; autoencoder; Variational autoencoder;

    Abstract : In the ever-changing landscape of the fishing industry, demands for automating specific processes are increasing substantially. Predicting future events eliminates much of the existing communication latency between fishing vessels and their customers and makes real-time analysis of onboard catch possible for the fishing industry.

  5. 4. Solving the Hamilton-Jacobi-Bellman Equation for Route Planning Problems Using Tensor Decomposition

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

    Author : Albin Mosskull; Kaj Munhoz Arfvidsson; [2020]
    Keywords : Autonomous vehicles; HJB equation; Tensordecomposition; Tensor Train decomposition;

    Abstract : Optimizing routes for multiple autonomous vehiclesin complex traffic situations can lead to improved efficiency intraffic. Attempting to solve these optimization problems centrally,i.e. READ MORE

  6. 5. Domain Expertise–Agnostic Feature Selection for the Analysis of Breast Cancer Data

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

    Author : Susanna Pozzoli; [2019]
    Keywords : breast cancer; clustering; clustering performance evaluation; feature selection; proteomics; unsupervised learning;

    Abstract : At present, high-dimensional data sets are becoming more and more frequent. The problem of feature selection has already become widespread, owing to the curse of dimensionality. Unfortunately, feature selection is largely based on ground truth and domain expertise. READ MORE
