  1. 1. Artificial Transactional Data Generation for Benchmarking Algorithms

    University essay from Umeå universitet/Institutionen för fysik

    Author : Veronica Lundgren; [2023]
    Keywords : Data Analytics; Synthetic Data; Statistical Distribution; Embedding; Transactional Data;

    Abstract : Modern retailers have been collecting more and more data over the past decades. The increased sizes of collected data have led to higher demand for data analytics expertise tools, which the Umeå-founded company Infobaleen provides. A recurring challenge when developing such tools is the data itself. READ MORE

  3. 2. An empirical study of the impact of data dimensionality on the performance of change point detection algorithms

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

    Author : Léo Noharet; [2023]
    Keywords : Time series segmentation; Change point detection; Multivariate time series; Data dimensionality; Tidsserie-segmentering; Förändringspunkts detektering; Mulitvariabla tidsserier; Data dimentionalitet;

    Abstract : When a system is monitored over time, changes can be discovered in the time series of monitored variables. Change Point Detection (CPD) aims at finding the time point where a change occurs in the monitored system. READ MORE

  4. 3. Remote Sensing of Cryospheric Surfaces : Small Scale Surface Roughness Signatures in Satellite Altimetry Data

    University essay from Umeå universitet/Institutionen för fysik

    Author : Petter Ideström; [2023]
    Keywords : Remote sensing; Altimetry; Arctic; Cryosphere; ICESat-2; Cryosat-2; Svalbard;

    Abstract : The Arctic cryosphere is experiencing a higher rate of warming compared to the rest of the world due to Arctic amplification. As glacier elevation change provide reliable evidence of climate change it is routinely measured by satellite altimeters. READ MORE

  5. 4. Multi-factor approximation : An analysis and comparison ofMichael Pykhtin's paper “Multifactor adjustment”

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Michael Zanetti; Philip Güzel; [2023]
    Keywords : Credit risk; Value at Risk; Expected Shortfall; Monte Carlo simulation; Advanced Internal Rantings-Based models; Kreditrisk; Value at Risk; Expected Shortfall; Monte Carlo simulation; Advanced Internal Rantings-Based-modeller;

    Abstract : The need to account for potential losses in rare events is of utmost importance for corporations operating in the financial sector. Common measurements for potential losses are Value at Risk and Expected Shortfall. These are measures of which the computation typically requires immense Monte Carlo simulations. READ MORE
