  1. 1. An investigation of average stable ranks : On plane geometric objects and financial transaction data

    University essay from KTH/Matematik (Avd.)

    Author : Linn Odelius; [2020]
    Keywords : Topological data analysis; TDA; Mathematics; Stable rank; Topology; Data analysis; Financial transactions; Topologisk dataanalys; Topologi; TDA; Matematik; Teoretisk Matematik; Dataanalys; Finans; Stabil rang;

    Abstract : This thesis concerns the topological features of plane geometric shapes and financial transaction data. Topological properties of the data such as homology groups and their stable ranks are analysed. READ MORE

  2. 2. Instance-level Object Detection of Grocery Store items using R-CNN:s

    University essay from Lunds universitet/Matematik LTH

    Author : Erik Rydén; [2019]
    Keywords : Image analysis; simulation; r-cnn; Mathematics and Statistics;

    Abstract : Currently, the best ways to perform object detection in an image is to use a neural network trained on large sets of annotated data. However, in certain environments, the number of objects is large and gathering a sufficiently big set of annotated data is prohibitively expensive. READ MORE

  3. 3. Binary classification of HRV signals

    University essay from Lunds universitet/Matematisk statistik

    Author : Rebecca Lütz; [2019]
    Keywords : Mathematics and Statistics;

    Abstract : Heart rate variability, commonly abbreviated as HRV, displays the variance between consecutive heartbeats. This variance occurs naturally but can change due to stress and problems with the cardiac system. HRV is therefore widely used for medical research. READ MORE

  4. 4. Multilabel text classification of public procurements using deep learning intent detection

    University essay from KTH/Matematisk statistik

    Author : Adin Suta; [2019]
    Keywords : Natural language processing; text classification; deep learning; applied mathematics; recurrent neural network; word embedding; Maskininlärning; textklassificering; artificiella neruonnät; tillämpad matematik;

    Abstract : Textual data is one of the most widespread forms of data and the amount of such data available in the world increases at a rapid rate. Text can be understood as either a sequence of characters or words, where the latter approach is the most common. READ MORE

  5. 5. Exploring Object Detection and Recognition Methods for Automated Book Inventory

    University essay from Lunds universitet/Matematik LTH

    Author : Anna Svensson; [2019]
    Keywords : Object Detection; Deep Learning; Automated Book Inventory; Computer Vision; Data Augmentation; Mask R-CNN; Triplet Loss; Mathematics and Statistics;

    Abstract : As more modern technical devices with cameras are accessible to people, more photos are taken and the amount of data that is available has vastly increased. Researchers have learnt to utilise this and use images for various purposes with Deep Learning based Computer Vision. READ MORE
